		Objective: To elucidate differences between large B cell lymphoma(LYM) and glioblastoma(GBM) using histogram analysis of T1WI, T2WI and contrast enhanced T1WI signal intensity maps based on entire tumor region, and then to evaluate the differential diagnosis value between them. Materials and Methods: Sixteen patients with LYM(9 males, 7 females; mean age 57.9±10.1 years old) and twenty patients with GBM(10 males, 10 females; mean age 57.8±11.8 years old) were enrolled in this retrospective study, and all tumors were pathologically confirmed. All patients undertook conventional MRI scan including T1WI, T2WI and contrast enhanced T1WI. Regions of interest(ROIs) containing the entire tumor were manually drawn in each slice of the T1WI, T2WI and contrast enhanced T1WI signal intensity maps. The histogram and all its parameters were obtained from the 3D ROI of T1WI, T2WI and contrast enhanced T1WI signal intensity using Omni-Kinetics software. Histogram parameters included min intensity, max intensity, mean value, standard deviation, variance, skewness, kurtosis, uniformity, entropy, the 10th, 25th, 50th, 75th and 90th percentiles. All parameters were compared between groups. The joint variable(JV) was calculated using the logistic regression analysis model. Receiver operating characteristic curve(ROC) was used to assess the differential ability of all parameters between LYM and GBM. Results: In the contrast enhanced T1WI signal histogram parameters, min intensity and uniformity of LYM were higher than GBM, but kurtosis of LYM were lower than GBM(P＜0.05). The negative skewness was present in LYM and that was positive in GBM(P＜0.05). In T1WI and T2WI signal intensity histogram parameters, standard deviation and variance of LYM were lesser than those of GBM, but uniformity was increased in LYM than GBM(P<0.05). According to ROC analysis, the skewness(cutoff value=0.007 8, area under the curve(AUC)=0.819) was considered as the best parameter for diagnosis of LYM and GBM in the contrast enhanced T1WI, with the sensitivity of 65% and specificity of 87.5%. Moreover, in the T1WI histogram parameters, the standard deviation and variance were the most optimal parameters(cutoff value=78.02, 6 087.64; AUC=0.787, 0.787) for distinguishing LYM and GBM with sensitivity of 75% and specificity of 81.2%. In the T2WI histogram parameter, the standard deviation and variance were the most optimal parameters(cutoff value=452.68, 204 937; AUC=0.7, 0.7) for distinguishing LYM and GBM with sensitivity of 55% and specificity of 81.2%. And when optimal cut point of the joint variable was 0.55 for diagnosis of LYM and GBM, the area under the AUC(0.881) was maximum with the sensitivity of 80% and specificity of 87.5%. Conclusion: Histogram analysis based on the ROI of tumor of T1WI, T2WI and contrast enhanced T1WI signal can provide more information to identify large B cell lymphoma and glioblastoma, and can improve the diagnostic ability of them combined with histogram parameters. It can provide a reliable objective basis for the identification of them.

		Objective: To explore the value of ADC whole-tumor histogram in differentiating glioblastom from solitary brain metastasis. Methods: Retrospective analysis of 30 cases of glioblastom and 28 cases of solitary brain metastasis which were pathologically confirmed was done. Region of interest(ROI) on each slice of ADC maps including tumor was drawn and the histogram was analyzed. The two steps were both conducted by the software Mazda. The histogram parameters were analyzed statistically to find out if there is significant difference between the two groups. Next, receiver operating characteristic(ROC) curve was drew to assess diagnostic efficiency. Results: As for the 9 parameters extracted from histogram, the difference of the mean, skewness, the 1th, 10th, 50th, 90th, 99th percentiles between the two groups showed statistical significance(P<0.05). Areas under the ROC curve were 0.792, 0.658, 0.674, 0.736, 0.801, 0.735, 0.699, respectively. The sensitivity and the specificity of mean value in differentiation were 70.0% and 78.6%, respectively. And those for skewness, 1th percentile, 10th percentile, 50th percentile, 90th percentile and 99th percentile were 60.7% and 60.0%, 76.7% and 64.3%, 70.0% and 67.9%, 63.3% and 78.6%, 70.0% and 75.0%, 70.0% and 60.7%, respectively. Conclusion: ADC whole-tumor histogram analysis can be used as an important supplementary method to differentiate glioblastom from solitary brain metastasis.

	852	The application value of single energy metal artifact reduction technique in the follow-up of postoperative patients with intracranial aneurysms
		RAN Yan-yong1, PAN Yu-ning2, CHEN Zhao-qian2, HUANG Qiu-li2
		DOI: DOI:10.12117/jccmi.2018.12.004
		Objective: To evaluate the effect of a single-energy metal artifact reduction(SEMAR) technique for metallic implantation materials artifacts reduction and perfusion parameters in brain imaging. Methods: Computed tomography angiography(CTA) and CT perfusion were performed on 55 patients with implanted metallic materials in the brain. All CT examinations were performed on a 320-row CT scanner. No-SEMAR images were reconstructed with iterative reconstruction alone, and SEMAR images were reconstructed with iterative reconstruction plus the SEMAR algorithm. Noise(N-measured on the image with the most pronounced artifact), contrast-to-noise ratio(CNR), artifact index(AI), maximum diameter of artifact, image quality score, and cerebral perfusion parameters were compared between the two groups. Two radiologists visually evaluated the metallic artifacts using a four-point scale and a double blind method. Results: Compared with No-SEMAR images, noise, artifact diameter, and artifact index were reduced significantly after images were reconstructed using the SEMAR algorithm(P<0.01). The subjective image quality score and contrast-to-noise ratio increased significantly(P<0.01). The perfusion parameters(blood flow, blood volume, and mean transit time) obtained between the No-SEMAR and SEMAR groups exhibited linear correlation(P<0.01). Conclusion: The SEMAR algorithm significantly reduces artifact from implanted metallic materials in the brain and can potentially increase CT image quality without influencing cerebral blood perfusion parameters.

		WANG Wei, LI Ru-xue, ZHANG Nian
		DOI: DOI:10.12117/jccmi.2018.12.005
		Objective: To understand the rule of velocity of water molecules in normal vitreous body at different ages, so as to find vitreous body abnormalities early, and to take early treatment or intervention. Methods: From July 2016 to December 2017, a total of 162 normal persons(324 eyes) were retrospectively analyzed. MRI data was divided into 9 groups according to age: A group 0~<10 years old, B group 10~<20 years old, C group 20~<30 years old, D group 30~<40 years old, E group 40~<50 years old, F group 50~<60 years old, G group 60~<70 years old, H group 70~<80 years old, I group 80~<90 years old. MR diffusion weighted imaging(Propeller-DWI) of two eyeballs and vitreous body in each age group was performed, and the apparent diffusion coefficient(ADC) value of the region of interest was measured. Results: Variance analysis showed that the ADC value of the vitreous body increased first and then decreased with age, and then tended to be stable. There was a statistically significant difference between the two groups(P=0.00). Conclusion: The movement speed of normal vitreous body water molecules rises first and then decreases with the increase of age, and then tends to be stable.

		DU Qi-gen, MI Xiang-qin, XU Hong-wei, SHANG Wei-min, ZHOU Li-ping, CHEN Wei
		DOI: DOI:10.12117/jccmi.2018.12.006
		Objective: To investigate the clinical value of cardiac motion quantification(CMQ) technique in evaluating left ventricular systolic function in patients with polycystic ovary syndrome complicated with insulin resistance(PCOS-IR). Methods: Fifty-five patients with polycystic ovary combined with insulin resistance were selected as PCOS-IR group and 55 healthy volunteers were selected as control group. The CMQ technique was used to measure the subendocardial, epicardial and global longitudinal strain(Ls), radial strain(Rs) and circumferential strain(Cs) of systolic myocardium, and the difference of cross wall was calculated. At the same time, the rotation angle and torsional angle of the left ventricular short axis were measured, and the peak value of rotation angle gradient of cross wall and the peak value of torsional angle gradient of cross wall were calculated. The difference of all the parameters between the two groups was compared. Results: ①Left ventricular systolic Ls: From the basal to apical segments, it showed an increasing trend. The peak strain of the subendocardial myocardium at the same level was greater than that under the epicardial(P<0.05). The Ls and difference of cross wall in the PCOS-IR group were lower than those in the control group(P<0.05). ②Left ventricular short axis Rs: The level of papillary muscle was the largest, the mitral valve was the second, and the apical level was the smallest. And there was no statistical significance between the two groups(P<0.05). ③Left ventricular short axis Cs: Increasing from mitral valve level to apical level, the peak strain of the subendocardial myocardium at the same level was greater than that under the epicardial(P<0.05). Left ventricular systolic Cs and difference of cross wall in the PCOS-IR group were lower than those in the control group(P<0.05). ④Myocardial rotation and torsion angle: Those of subendocardium were higher than those of epicardial myocardium at the same level in the two groups(P<0.05). The rotation angles at the apical level, the rotation angles of left ventricular short axis mitral valve epicardium, and the torsional angles of the left ventricle in the PCOS-IR group were higher than those in the control group(P<0.05). The peak value of rotation angle gradient of cross wall and the peak value of torsional angle gradient of cross wall of left ventricular apical level in the control group were higher than those in the PCOS-IR group(P<0.05). The subendocardial rotation angle and the whole rotation angle of mitral valve in the PCOS-IR group were higher than those in the control group, and the angle gradient of transmural rotation in PCOS-IR group was lower than that of control group(P<0.05). Conclusion: CMQ technique can accurately detect the changes of left ventricular systolic function in patients with PCOS-IR, and can provide a new diagnostic basis for evaluating the early changes of myocardial systolic function in patients with PCOS-IR.

		DOI: DOI:10.12117/jccmi.2018.12.007
		Objective: To explore the value of transthoracic echocardiography(TTE) on observation the catheter tip of the internal jugular vein long-termcatheter in hemodialysis patients. Methods: From January 2016 to July 2017, 52 hemodialysis patients with the internal jugular vein long-termcatheter undertook TTE and X-ray, to observe the catheter tip, including its position, and other complication such as thrombosis. Results: In the 52 cases, catheter tips of 49 cases could be observed clearly by TEE(94.2%). Cathetertip localization rate was 87.8%(43/49), ectopic rate was 12.2%(6/49); while catheter tips of 48 cases could be observed clearly by X-ray(92.3%), the cathetertip localization rate was 89.6%(43/48), and ectopic rate was 10.4%(5/48). There was no statistically significant difference(P>0.05). Kappa test showed a better consistence(P<0.05). Thrombosis was found in fourteen catheter tips by TTE, while none could be found by X-ray. All the ectopic severe cases were retreated to ideal position under the guidance of TTE, and the success rate was 100%. For the thrombosis patients, treatment of thrombolysis was guided. Conclusion: TTE can clearly display catheter tip, observe its position and the presence of thrombus. It can help to adjust ectopic catheter tip and evaluate thrombolysis effect. It’s noninvasive, convenient, safe, rapid and accurate. It shows an important clinical value.

	872	Diagnostic value of CTE in inflammatory bowel disease from misjudged case
		PENG Lai, HAN Yun-xue, GU Li-fang
		DOI: DOI:10.12117/jccmi.2018.12.009
		Objective: To explore the diagnostic value of CT enterography(CTE) in inflammatory bowel disease(IBD). Methods: The imaging data and clinical data of 1 case of Crohn’s disease(CD) misdiagnosed as ulcerative colitis(UC) were analyzed retrospectively and combined with literature review. Results: A male patient of 57 years old suffered from the 2nd peak onset of UC, with frequent pus and blood stools and the lesion is limited to the colon, a common spot for UC. The first diagnosis of “perianal abscess” conforms to the clinical features of CD, and CTE showed that the lesion involved the intestinal wall of the whole layer, with segmental distribution, a large number of hyperplasia of blood vessels around bowel during the active period, which is consistent with the typical imaging of CD. Conclusions of the twice colonoscopy were “UC-severe total colonic type” and “IBD-CD?”. The patient was eventually diagnosed as a CD with pathological extraction of non-cheese granuloma. Conclusion: There are overlap in both clinical and imaging findings between UC and CD. When the lesion is confined to the colon, the observation of image details and the collection of medical history can help to identify. UC is occurring in the mucosa and submucosa, with general continuous distribution. CTE shows no characteristic changes, and colonoscopy and biopsy are the keys to the establishment of UC diagnosis. Segmental distribution, permeable wall inflammation and “Comb sign” are common CTE findings in CD. CTE is more valuable for CD diagnosis. The diagnosis of CD is preferred when perianal lesions are the first signs. The diagnosis of inflammatory bowel disease unclassified(IBDU) can be made when it is difficult to identify the two.

		Objective: To investigate the value of bi-exponential model of intravoxel incoherent motion(IVIM) in diagnosis of different stages, pathological types and subtypes of cervical cancer. Methods: Sixty-five patients with pathological diagnosis of cervical cancer were collected. Apparent diffusion coefficient(ADC), slow apparent diffusion coefficient(ADCslow), fast apparent diffusion coefficient(ADCfast) and fraction of ADCfast(Ffast) were recorded using mono-exponential signal decay model and bi-exponential signal decay model, which were then compared statistically between different stages, pathological types and subtypes. Results: In cervical cancer group, ADCslow of infiltration group was lower than non infiltration group, with statistically significant difference(P<0.05). ADCfast and Ffast of infiltration group were higher than non infiltration group, and the difference were not statistically significant(P>0.05). ADCslow of squamous cell carcinoma was lower than adenocarcinoma cell carcinoma. ADCfast and Ffast of squamous cell carcinoma were higher than adenocarcinoma cell carcinoma, and the difference was statistically significant(P<0.05). ADCslow of cases of high differentiation was higher than cases of middle～low differentiation, with statistically significant difference(P<0.05), while ADCfast and Ffast were not statistically significant(P>0.05). Receiver operating characteristic curve analysis showed that ADCslow was the most effective in diagnosis cervical cancer of different pathological types and subtypes. Conclusion: ADCslow has a high value in diagnostic cervical cancer of different stages and subtypes.

	881	The value of GI-RADS ultrasonographic stratification combined with serum CA-125 in diagnosis of adnexal masses
		XU Ai-ling, NIE Fang, WANG Juan-juan, LV Wen-hao, ZHANG Xue-yun
		DOI: DOI:10.12117/jccmi.2018.12.011
		Objective: To analyze the value of gynecologic imaging reporting and data system(GI-RADS) ultrasonographic stratification combined with serum CA-125 in diagnosing adnexal masses. Methods: Ultrasound manifestations of 159 adnexal masses confirmed by pathology were retrospectively analyzed according to 6 ultrasonic features: wall thickness, separation, ascites, papillary bulge, solid component, and internal blood flow. Then the adnexal masses were graded with GI-RADS ultrasonographic stratification, using the serum CA-125 data to calibrate the GI-RADS ultrasonographic stratification. Results: Of the 6 ultrasound signs, the Youden index and accuracy of the internal blood flow were the highest, 63.1% and 85.5% respectively. Those of the wall thickness were the minimum, 16.8% and 72.3% respectively. Compared to GI-RADS ultrasonographic stratification, GI-RADS ultrasonographic stratification combined with serum CA-125 showed higher Youden index(79.4%, 76.4%) and lower accuracy(91.2%, 93.1%). Conclusions: Of the 6 ultrasound signs, diagnostic efficiency of internal blood flow is the highest and that of wall thickness is the lowest in diagnosing adnexal malignancies. Both GI-RADS ultrasonographic stratification and GI-RADS ultrasonographic stratification combined with serum CA-125 in diagnosis of adnexal malignancies have high diagnostic value and no significant difference in diagnostic efficiency.

	884	The clinical significance of the sequestrum sign in limb bone imaging
		ZHANG Yuan, CHEN Hai-song, FENG Wei-hua, ZHOU Rui-zhi
		DOI: DOI:10.12117/jccmi.2018.12.012
		Objective: To study the differences of the occurrence rate of “sequestrum” sign in different diseases of extremity. Methods: Patients with limb bone diseases and bone destructive lesions in our hospital from 2008 to 2016 were retrospectively analyzed. Two hundred and fifty-three patients with 13 types of diseases that proved by pathology or clinical follow-up were included in the observation. CT examination was performed in all cases, radiography in 163 cases, MRI in 144 cases, and all the three kinds of examination was performed in 66 cases. CT images were used to observe the occurrence of the “sequestrum” sign and to calculate the occurrence rate of the sign. χ2 test was used to perform statistical analysis. Results: “Sequestrum” sign appeared in 92.3%(12/13) of the disease types and in 43.1%(109/253) of all the cases. But occurrence rate of “sequestrum” sign differed in different types of the disease, osteomyelitis 52.9%(27/51), skeletal tuberculosis 70.0%(7/10), metastatic carcinoma 47.1%(48/102), fibrous dysplasia 32.1%(9/28), and giant cell tumor of bone 22.2%(6/27). The occurrence rate was the highest in bone tuberculosis(χ2=11.532, P<0.05), followed by osteomyelitis and bone metastases. Other types with less cases also showed “sequestrum” sign, including 3 cases of Langerhans cell histiocytosis(3/8), 1 case of primary lymphoma of bone(1/6), 2 cases of malignant fibrous tumors(2/5), 3 cases of aneurysmal bone cyst(3/5), 1 case of osteofibrous dysplasia(1/8), 1 case of angiosarcoma of bone(1/1), and 1 case of fibrosarcoma of bone(1/1). The sign was not found in the only one case of primitive neuroectodermal tumor(PNET)(0/1). Conclusion: “Sequestrum” sign can be seen in vast majority of limb bone disease of benign and malignant bone destructive lesions, but it is seen in skeletal tuberculosis most commonly, followed by osteomyelitis and bone metastases. We should combine this sign with other signs to make qualitative diagnosis and avoid misdiagnosis.

		QI Qing-hua, WANG Jun-kui, ZHOU Yuan-yuan, ZENG Qing-hu, WU Zhi-bin, ZhANG Rui-fang
		DOI: DOI:10.12117/jccmi.2018.12.014
		Objective: To explore the application of color superb microvascular imaging(cSMI) in evaluating the rheumatoid arthritis(RA) in the active period. Methods: Sixty-two patients with RA in the active period were collected. Ultrasound was used to examine the wrist(Wri) joints and metacarpophalangeal(MCP) joints and proximal interphalangeal(PIP) joints of each patient’s bilateral hands. The numbers of thickened synovial joints were recorded. Blood flow signal of the thickened synovial joints was checked by the cSMI and power doppler ultrasound(PDUS) separately. Color flow signal was graded by the semi-quantitative scoring systems. The correlations between the blood flow signal score of PDUS and cSMI and 28 joint disease activity scores(DAS28), blood sedimentation(ESR) and C-reactive protein(CRP) were analyzed. Results: ①Four hundred and forty joints showed synovial thickening, 82 Wri and 328 MCP+PIP. The proportion of blood flow signal detected by cSMI in thickened synovial membranes of Wri was 83.9％, while that of PDUS was 62.5％. The proportion of blood flow signal detected by cSMI in thickened synovial membranes of MCP+PIP was 81.4％, while that of PDUS was 63.7％. The differences of blood flow signal rate between both Wri and MCP+PIP were statistically significant, so was the comparison of two imaging patterns(P＜0.05). ②The differences of grading of PDUS and cSMI between Wri and MCP+PIP were statistically significant(P＜0.05). Compared with PDUS, cSMI could raise the blood flow classification level. ③PDUS and cSMI blood flow signals grading were positively correlated with CRP, ESR and DAS28(P＜0.05). Compared with PDUS, the correlation between cSMI and CRP, ESR and DAS28 increased(P＜0.05). Conclusions: cSMI can more prominently detect the thickened synovial blood flow of RA in the active period, and can also assess the disease activity better.
