ZHANG Jing-wen;LIU Tie-li;MIAO Yan-wei;WU Jian-lin;WANG Hong-xia
DOI:
Objective: To evaluate the correlation between diffusion tensor imaging(DTI) and clinical scores in traumatic brain injury(TBI), and to explore the value of DTI in evaluating the severity of injury and to predict the prognosis of TBI. Methods: Fifty-nine cases of TBI patients with a total of 89 exams and 60 cases of matched healthy controls underwent conventional MRI and DTI exams. FA and ADC in the corpus callosum, internal capsule, and brainstem of controls and TBI patients in the acute phase, subacute phase, and 1~3 months post-trauma were measured. The data between controls and TBI patients, as well as between mild and moderate-severe TBI groups, were compared. The results of different time points were correlated with the GCS scores respectively. The differences of MRI data between different outcome groups were also analyzed. Results: FA of the majority of the observation sites was significantly reduced in the three post-injury phases of TBI patients. FA positively correlated with GCS scores significantly and the reduction of FA was more significant in poor-outcome group. Even 1~3 months after trauma, FA of the corpus callosum and internal capsule still exhibited significant decrease. ADC presented a biphasic trend with time following trauma, and its correlations with GCS and GOS scores were not as significantly as FA. Conclusion: The decreased FA correlates well with the severity of injury and can indicate the prognosis of TBI patients. Even 1~3 months after trauma, the injury of axons can still be revealed by DTI. The correlations of ADC with the injury severity and prognosis are not as sensitive and accurate as FA.

DOI:
Objective: To investigate the carotid arterial elasticity in patients with high-normal blood pressure and hyperlipidemia by echo tracking technique. Methods: We selected 51 patients with highnormal blood pressure and hyperlipidemia, and 62 patients with high-normal blood pressure. Another 50 healthy cases were selected as normal control. Echo tracking technique was used to evaluate the carotid elastic modulus, including the stiffness parameter(β), pressure-strain elastic modulus(Ep), arterial compliance(AC), augment index(AI) and pulse wave conducting velocity(PWVβ). The intima-media thickness(IMT) was measured on routine ultrasonography. Carotid artery of the three groups showed no abnormalities on routine ultrasonography. Results: There was no difference in carotid elasticity between left and right side. Compared with the normal control group, β increased conspicuously in high-normal blood pressure and hyperlipidemia group and the high-normal blood pressure group, while AC was significantly lower. There was no difference in β and AC between the high-normal blood pressure and hyperlipidemia group and the high-normal blood pressure group. There was significant difference in Ep and PWVβ among the three groups, while there was no difference in AI and IMT. Conclusions: The elasticity of the carotid artery in high-normal blood pressure and hyperlipidemia group decreases obviously. Echo tracking technique may find the early change of the arterial elasticity, and it is superior than routine ultrasonography and may be helpful to prevent cardiac and cerebrovascular disease.

DOI:
Objective: To explore the effect of hypoxia on carotid compliance and related cytokines in anti-seismic soldiers acute exposed to high altitude by using wave intensity(WI) technology and detection of changes of hypoxia induced factor(HIF-1α) and vascular endothelial growth factor(VEGF). Methods: One hundred anti-seismic soldiers acutely exposed to plateau within seven days at Yushu(the high altitude group) and one hundred healthy soldiers living on the plains(the control group) were enrolled, pressure-strain elastic modulus(Ep), stiffness parameter(β), arterial compliance(AC), argumentation index(AI) and pulse wave velocity(PWV-WI) were detected using WI technology, meanwhile VEGF and HIF-1α were measured. Results: Compared with the control group, HIF-1α, VEGF and PWV-WI were higher in the high altitude group(P<0.05). The Ep, β, AC, AI had no significant different between the two groups(P>0.05). Conclusions: In a hypoxia environment, increased HIF-1α and VEGF may had a regulating effect on carotid compliance. Carotid artery elasticity-pulse wave velocity is a sensitive variable reflecting acute high altitude hypoxia reaction.

DOI:
Objective: To assess the relation between intravascular clots of pulmonary artery and lung perfusion defects with dual source CT low-dose contrast perfusion imaging. Materials and Methods: Image quality of low-dose and conventional dose dual energy lung perfusion imaging(DEPI) in 15 patients without pulmonary embolism(PE) was analyzed. Twenty consecutive patients with suspected PE underwent dual source CT low-dose contrast perfusion imaging. CT pulmonary angiography(CTPA) and lung perfusion images were analyzed at the same time. Intravascular clots of pulmonary artery were analyzed, including the location, number and morphology by the axial image and three-dimensional reconstruction of CTPA. Lung perfusion defects and its location, extent were evaluated with lung PBV software on the workstation. The relationship between intravascular clots of pulmonary artery and lung perfusion defects were analyzed statistically. Results: No significant difference was found in the image quality of low-dose and conventional dose DEPI of patients without PE(P>0.05). One hundred and two perfusion defects were found in 13 patients by pulmonary perfusion imaging, including lobular, segmental and subsegmental perfusion defects. Six perfusion defects in 4 cases had no clear intravascular clots. Images of axial CTPA and three-dimensional reconstruction showed 43 intravascular clots in 11 patients. Two cases with 5 intravascular clots depicted by CTPA showed no perfusion defects. Nine cases showed both intravascular clots and perfusion defects, with 21 perfusion defects unrelated to the blood supply areas of pulmonary artery(8 segmental and 13 subsegmental), and the remaining 75 perfusion defects consistent with the blood supply areas of pulmonary artery. Conclusion: There is unexpected dissociation between the intravascular clots of pulmonary artery and lung perfusion defects. Analysing the perfusion maps and CTPA of dual source CT low-dose contrast perfusion image will improve the accuracy of diagnosis of PE.

DOI:
Objective: To assess the short-term effects of cardiac resynchronization therapy(CRT) via three-dimensional speckle tracking imaging(3D-STI). Methods: Fifteen congestive heart failure patients who underwent CRT and twenty normal volunteers were enrolled. Toshiba Artida 4D system with PST-25SX probe were used to perform 3D-STI in heart failure patients and the controls, and the heart failure patients were studied before and one week, one month, three months after CRT. The left ventricular end diastolic volume(LVEDV), left ventricular end systolic volume(LVESV), left ventricular ejection fraction(LVEF) were obtained. The left ventricular dyssynchrony data sets which include the standard deviation of time to peak area tracking in the 16 left ventricular segments(AT-SD) and the maximum difference of time to peak area tracking in the 16 left ventricular segments(AT-Dif) were also investigated. Two independent samples t test and the ANOVA for one group repeated measures were used to perform the data analysis. Results: Compared with the controls, LVEDV, LVESV, AT-SD and AT-Dif of the heart failure patients were significantly bigger, and LVEF of the heart failure patients were significantly smaller(P<0.05). One week after CRT, the left ventricular dyssynchrony data sets were decreased(P<0.0083); after that, the changes of left ventricular dyssynchrony data sets were not statistically significant(P>0.0083). LVEDV, LVESV descended with the time(P<0.0083); LVEF ascended with the time(P>0.0083). Conclusion: 3D-STI provides valuable information to assess the curative effect of CRT.

248 Clinical evaluation of nonalcoholic fatty liver disease with in-phase and out-of-phase subtraction MR imaging and T2 corrected proton 1H-MR spectroscopy
SHI Yu;GUO Qi-yong;XIA Fei;ZHANG Lan;BIAN Sheng-xin
DOI:
Objective: To compare the T1 weighted in-phase and out-of-phase magnetic resonance imaging(IP-OP) with subtraction techniques and T2 corrected proton 1H-MR spectroscopy(1H-MRS) in the assessment of liver fat content(LFC) in patients with nonalcoholic fatty liver disease. Methods: IP-OP MR imaging and 1H-MRS were performed in 42 patients using a 3T MR unit. Subtraction images were made from pairs of IP and OP images. T2 relaxation measurements were performed in five patients by using a multi echo PRESS sequence. LFC measured by IP-OP and 1H-MRS were compared with histological results using spearman analysis and Mann-Whitney U test. Results: LFC measured by 1H-MRS were corrected by T2 relaxation(T2water=33.1 ms, T2fat=64.2 ms). Sensitivity and specificity of IP-OP substraction and 1H-MRS to detect steatosis was 89.2%, 100% and 91.2%, 100%, respectively. IP-OP MR imaging and 1H-MRS measurements of LFC had strong correlation with histopathologic steatosis assessment(r=0.80, 0.92; P＜0.01). IP-OP and 1H-MRS showed differences across steatosis grades: none versus mild, mild versus moderate and moderate versus severe grade(expect that IP-OP cannot differentiate moderate from severe grade, Z≤-2.54, P＜0.01). The LFC measured by IP-OP and 1H-MRS were significantly lower than pathology(expect for non fatty liver group, Z≤-2.21, P＜0.05). Conclusion: IP-OP is a quick and effective way to detect steatosis for clinic. 1H-MRS has better diagnostic accuracy in depicting hepatic steatosis than IP-OP.

TAO Ran;CUI Jin-guo;ZHANG Jiu-quan;WANG Jian
DOI:
Objective: Quantitative measurement of R2* in cirrhotic liver with MR multi-echo T2* sequence, and analyze its relationship with concentration of serum ferritin. Materials and Methods: Thirty-two healthy individuals and 42 patients with hepatic cirrhosis after chronic type B hepatitis and alcoholic cirrhosis had MR multi-echo T2* examination. The blood sample of patients was collected to assay concentration of serum ferritin. The SPIN software was used to measure the T2* value in health participants and cirrhotic patients. R2* value, which was the reciprocal of T2* value, was used to perform Pearson correlation analysis with serum ferritin concentration. Results: R2* value of healthy individuals and liver cirrhotic patients was (67.02±12.32) Hz, and (85.30±28.48) Hz, respectively. Independent sample t test showed significant difference between the two groups. The serum ferritin concentration of liver cirrhotic patients was (165.5±104.4) ng/mL. R2* value had significant correlation with serum ferritin concentrations in 42 patients (r=0.710, P=0.000). Conclusion: R2* value was higher significantly in liver cirrhotic patients than that in healthy individuals, and had significant correlation with serum ferritin concentrations. It could be used for non-invasive quantitative measurement of the iron deposition in hepatic cirrhosis in vivo.

LIANG Ping;FANG Hua-sheng;CHENG Geng-rui;DENG Lin
DOI:
Objective: To evaluate the value of the minimum intensity projection(MinIP) and surface reconstruction(CPR) of multi-slice CT(MSCT) in biliary obstruction diseases. Materials and Methods: Forty-five patients with obstructive jaundice underwent MSCT scanning, and all the images were post processed with MinIP+CPR technique and analyzed. Results: There were 25 patients with benign lesions, including 12 cases of bile duct stones, 5 cases of common bile duct inflammation, 6 cases of gallstones and cholangitis and 2 cases of pancreatitis, 20 patients had malignant lesions, including 10 cases of cholangiocarcinoma, 3 cases of gallbladder involving the bile duct, 4 cases of pancreatic cancer involving the bile duct, 3 cases of ampullary carcinoma. The accurary for the location of benign and malignant lesions by MinIP+CPR were 92.0% and 95.0% respectively, and the qualitative coincidence rate was 88.0% and 90.0%. To some extent, images of MinIP+CPR techniques corrected those of axial and multi-planar reconstruction(MPR) techniques for telling the location, quantity and nature of the lesions, which especially improved diagnostic accuracy(P<0.05) of malignant lesions. Conclusion: MinIP+CPR techniques of MSCT can show the location and the nature of the disease more clearly, which is an essential and effective screening method for biliary obstruction, especially for malignant biliary obstruction diseases.

LUO Zhen-dong;YE Qiong-yu;CHEN Wei-guo;QIN Geng-geng;CHENG Yong;JIA Ming
DOI:
Objective: To analyze the CT characters of extra-abdominal aggressive fibromatosis, in order to achieve more information about the disease and to improve the diagnostic accuracy. Methods: The CT appearances of extra-abdominal aggressive fibromatosis in nine cases were reviewed. All the cases were confirmed by operation and pathology. Results: In the nine cases of extra-abdominal aggressive fibromatosis, seven tumors were located in soft tissue(including five in chest wall, two in neck and one in thigh) and two in bone(sacrum and maxillary respectively). On pre-contrast CT images, seven tumors in soft tissue showed equal or mild lower density than muscle, with bone destruction in three cases. On enhanced CT images, three cases showed mild to moderate enhancement, and four showed significantly enhancement. Aggressive fibromatosis of bone were expansive lytic with bony rim in one case and trabecular bone in the other case. Conclusion: Aggressive fibromatosis is a rare soft tissue tumor. It has certain characteristic performance of CT, yet final diagnosis should be based on histopathology.
