GAO Jie1, ZHANG Dong-sheng1, YAN Xue-jiao1, TANG Min1, FAN Ya-juan2,
DOI: 10.12117/jccmi.2020.01.001
Objective: To explore whether auditory hallucination(AH) in schizophrenia are associated with the white matter abnormalities in tracts associated with language, auditory and memory/limbic networks in first episode and chronic schizophrenia patients. Methods: Twenty-one first-episode(FE-AH) and 12 chronic(Chronic-AH) patients who suffered from AH and 26 match healthy controls(HC group) were enrolled. Diffusion tensor imaging with tract-based spatial statistics was performed to assess the white matter changes between the patient group and the HC group. Results: Decreased fractional anisotropy and increased radial diffusivity were found in the patient groups compared with the HC group in multiple white matter tracts including the corpus callosum, superior longitudinal fasciculus, inferior fronto-occipital fasciculus, uncinate fasciculus, cingulum, external capsule and anterior limb of the internal capsule. The Chronic-AH group showed more widespread white matter impairment than the FE-AH group. Furthermore, increased axial diffusivity was also observed in some discrete regions in the Chronic-AH group. Conclusion: Auditory hallucination in schizophrenia is accompanied with white matter abnormalities in tracts associated with the language, auditory and memory/limbic networks. Chronic-AH schizophrenia patients may present more severe neurodegeneration than those first-episode patients.

DOI: 10.12117/jccmi.2020.01.002
Objective: To investigate the correlation between apparent diffusion coefficient(ADC) and prognostic factor Ki-67 expression in non-Hodgkin’s lymphoma(NHL) of head and neck and the effect of ADC value in evaluating the efficacy of NHL chemotherapy. Methods: A total of 42 patients underwent MRI examination at our hospital and confirmed by pathology as NHL of head and neck from September 2016 to July 2018. They were divided into NK-T cell lymphoma(NKTCL) group and diffuse large B cell lymphoma(DLBCL) group, Ki-67 low expression group and Ki-67 high expression group, the changing group and the no changing group. The ADC value of each group was calculated and the correlation between the ADC value and the expression of Ki-67 was analyzed. Results: The average ADC value was negatively correlated with the Ki-67 index(r=-0.779, P=0.000). The average ADC value of low expression group was significantly higher than that of high expression group(P=0.000). The ADC values of Ki-67 low expression group and high expression group were negatively correlated with Ki-67 index(P＜0.05). The ADC values of DLBCL group and NKTCL group were negatively correlated with Ki-67 index(P＜0.05). The difference of the ADC value before and after chemotherapy in the changing group was significantly different(P＜0.05). The difference of ADC value of the changing group was significantly different with the no changing group(P＜0.05). Conclusion: The ADC value is related to the expression of Ki-67 in NHL of head and neck. The lower the ADC value is, the higher the Ki-67 index is in NHL. The changes of ADC value can monitor the effect of chemotherapy. Accordingly, DWI combined with MR routine scan can non-invasively evaluate the biological behavior in NHL of head and neck.

YAN Hong, LI Xiang, CHENG Hui-fang, WANG Xue-mei, ZHANG Yi-xia, KANG Shu
DOI: 10.12117/jccmi.2020.01.006
Objective: To investigate the influence factors of the sensitivity, specificity and accuracy of S-Detect. To analyze the diagnostic value and the agreement of the combined diagnosis with a radiologist specializing in breast lesions. Methods: Grouped by the influence factors of S-Detect, chi-square test was used to calculate and compare the sensitivity, specificity and accuracy of S-Detect. Logistic regression was used to analyze the relationship between various factors and the results of pathological diagnosis that was benign or malignant. Breast ultrasound and S-Detect were operated by a radiologist specializing in breast imaging. The other radiologist analyzed the ultrasonographic images of the breast masses according to the American College of Radiology Breast Imaging Reporting and Data System(BI-RADS), and then made the combined diagnosis on the results of S-Detect. The area under the receiver operating characteristic(ROC) curve and the agreement among the S-Detect, radiologist, combined diagnosis were calculated and compared. Results: In all the 581 lesions, pathological diagnosis showed 411 benign lesions and 170 malignant lesions. The false positive rate of  S-Detect in intraductal papilloma and which was between 2 cm to 4 cm was higher(P<0.05). The specificity of S-Detect was all higher than 80.00%. The sensitivity and specificity of S-Detect were not statistically significant in the groups of the age, the location of the lesions and the depth of the lesion. Three significant risk factors(age, S-Detect, the most largest size of lesions) for pathology were analyzed with logistic regression(P<0.05). Moderate agreement was seen in final assessments made by S-Detect, radiologist and combined diagnosis(the primary combined diagnosis)(Kappa=0.45, 0.571 and 0.65, respectively) with pathological results as the gold standard. Good agreement was seen in final assessments made by combined diagnosis in consideration of age and the largest size of lesions(the recombined diagnosis)(Kappa=0.76). The area under ROC curve was 0.78, 0.78, 0.84 and 0.89, respectively. Conclusion: The specificity of S-Detect was higher. The accuracy of S-Detect in intraductal papilloma was lower and the false negative rate of S-Detect in benign tumor of  lesions between 2 cm to 4 cm was higher. S-Detect is a clinically feasible diagnostic tool that can be used to improve the diagnostic value and the agreement of the radiologist and pathological diagnosis.

Objective: To evaluate the value of quantitative parameters of contrast-enhanced ultrasonography in differential diagnosis of benign and malignant lung lesions. Methods: Fifty-one cases of lung lesions diagnosed by puncture pathology were divided into benign group and malignant group, the quantitative parameters of contrast-enhanced ultrasonography time  intensity curve(TIC) and the time difference of contrast agent to lung lesions and adjacent lung tissues were quantitatively analyzed. Results: ①In the quantitative parameters of TIC, the contrast agent arrive time(AT) in the benign group was less than that in the malignant group, and the difference was statistically significant between the two groups(P<0.05). There was no significant difference in the time to peak(TTP), the rise time(RT), the maximum intensity(IMAX) and the rising slope(RS) between the two groups(P>0.05). ②Squamous cell carcinoma group and adenocarcinoma group were divided from malignant group. There was no significant difference in quantitative parameters of TIC between the two groups(P>0.05). ③The time difference of contrast agent to lung lesions and adjacent lung tissues in the benign group was less than that in the malignant group, and the difference was statistically significant between the two groups(P<0.05). The optimal cut-off point of the time difference was 2.5 s. Conclusion: ①The quantitative parameters of TIC have definite clinical value in the differential diagnosis of benign and malignant lung lesions. ②The time difference of contrast agent to lung lesions and adjacent lung tissues has certain value in the differential diagnosis of benign and malignant lung lesions. The time difference<2.5 s indicates that the lesions tend to be benign, and the time difference>2.5 s indicates that the lesions tend to be malignant.

DOI: 10.12117/jccmi.2020.01.009
Objective: To study the virtual monoenergetic image quality and radiation dose of dual-energy mode with single-energy mode for bronchial artery in dual-source dual-energy CT. To explore the clinical significance of dual-source CT dual-energy virtual single-energy technology in bronchial artery imaging. Methods: Sixty-four patients were randomly dived into 2 groups: dual-energy group and single-energy group, 32 cases for each group. 1.2 mL/kg of iodine contrast medium  (370 mgI/mL) for patients was injected via the antecubital vein at a rate of 4 mL/s, and 40 mL normal saline was added. One group of enhanced images was obtained for each patient in the single-energy group, and multiple groups of images ranging from 40 keV to 190 keV were generated in the dual-energy group, and the group with the highest contrast signal-to-noise ratio(CNR) was automatically obtained through virtual single-energy technology. A 5-point scale was carried out to evaluate angiography image quality by two radiologists subjectively. Mean CT attenuation value and standard deviation were measured to calculate the CNR and single-to-noise ratio(SNR). Volume computed tomography dose index(CTDI) and the dose-length product(DLP) for calculating radiation dose were recorded automatically. Subjective scores and quantitative parameters were compared via Mann-Whitney U test and T test respectively. Results: There were excellent agreements between two radiologists for grading right and left bronchial arteries respectively(all Kappa value>0.8). Image quality scores were significantly higher in dual-energy group compared with single-energy group for both right(P<0.001) and left(P=0.001) angiography branches. Compared with single-energy, dual-energy group demonstrated higher CT attenuation(P<0.001, P<0.001), standard deviation(P<0.001, P<0.001), CNR(P=0.001, P=0.003) and SNR(P=0.012, P=0.035) in right and left bronchial arteries respectively. There were no significant differences in two groups for CTDI and DLP respectively(P=0.097, P=0.132). Conclusion: Dual-energy bronchial artery CT angiography with virtual monochromatic technique has significant higher image quality which can better meet the need for diagnosis and preoperative evaluation.

DOI: 10.12117/jccmi.2020.01.010
Objective: By summarizing the echocardiography characteristics of Berry syndrome, the diagnostic value and thoughts of Berry syndrome were evaluated. Methods: The echocardiographic characteristics of six children diagnosed with Berry syndrome by CT examination or surgery in our hospital were retrospectively analyzed. The diagnostic value and thoughts of echocardiography were summarized and analyzed by reviewing relevant literature. The main pulmonary artery septum, ventricular septum, pulmonary artery branches and other conditions can be detected by multi-section view of apical five cavities, parasternal great artery short axis and pulmonary artery branch, and the condition of aortic arch can be displayed by long-axis view of superior thoracic aorta arch. Results: Six cases of Berry syndrome include: distal aortopulmonary septal defect, aortic origin of right pulmonary artery, interruption of aortic arch(type A), intact ventricular septum, and patent ductus arteriosus, combining with atrial septal defect in four cases, combining with patent foramen ovale in one case, one case with external cardiac malformation(hypospadias). One case of aortic origin of right pulmonary artery was missed. Conclusion: Echocardiography can be used as the preferred diagnostic method for Berry syndrome, which may be associated with extracardiac malformations. However, missing diagnosis may occur, which requires a clear idea of ultrasonic diagnosis.

DOI: 10.12117/jccmi.2020.01.013
Objective: To investigate the recurrence prediction value of apparent diffusion coefficient(ADC) based on whole tumor volume measurement in patients with epithelial ovarian cancer(EOC). Methods: A retrospective analysis of 49 patients with pathologically proven EOC who underwent preoperative DWI imaging(b=0, 800 s/mm2) was carried out. The post-processing software was used to map the region of interest of the whole tumor on the ADC map, and the texture parameters such as skewness, kurtosis, entropy, inertia, correlation, contrast, variance were extracted and analyzed. Multivariate Logistic regression analysis was used to determine the best predictor of recurrence, and the predictive efficiency of the relevant parameters for recurrence after surgery was evaluated by receiver operating characteristic curve. Results: Tumor size and ascites were higher in recurrence group than those in non-recurrent group. The differences were statistically significant(P<0.05). The difference between the two groups in FIGO staging was statistically significant. The parameters of texture analysis, including inertia, contrast, variance and entropy in recurrence group were higher than those in non-recurrent group. Kurtosis, quantile 10, quantile 25 and correlation in recurrence group were lower than those in non-recurrent group. The differences were statistically significant(P<0.05). ROC curve analysis showed that the area under the curve of kurtosis, inertia, correlation, tumor size and FIGO stage combined to prediction recurrence was the highest, 0.929. Conclusion: The preoperative texture analysis of ADC images based on total tumor volume helps predicting recurrence of EOC.

WANG Ting, HUANG Le-le, ZHANG Si-gong, LIU Ting, WANG Yuan, WANG Yin-di
DOI: 10.12117/jccmi.2020.01.014
Objective: To investigate the value of ultrasound elastography(UE) in assessing quadriceps tendon injury of active period in rheumatoid arthritis(RA). Methods: Forty healthy volunteers(control group) and forty RA patients were selected. The quadriceps tendons were divided into proximal, middle, and distal segments. According to the achilles tendon segmentation method. Using two-dimensional ultrasound and UE to examine the quadriceps tendon of the knee joint, and the results were recorded and graded. Quadriceps tendon can be divided into grade Ⅰ, grade Ⅱ, and grade Ⅲ. Grade Ⅰ tendons were considered as normal tendons, and grade Ⅱ and grade Ⅲ tendons were considered as abnormal or damaged tendons. Consistency test for tendon ultrasound diagnostic grading were evaluated by two evaluators. SPSS 22.0 was used for statistical analysis of data. Results: The number of abnormal quadriceps tendon of each segment detected by two-dimensional ultrasound was not statistically significant between the control group and the RA active group(P=0.173, P=0.072, P=0.242). The number of abnormal quadriceps tendon of proximal segments detected by UE was not statistically significant between the two groups(P=0.093), thus, there was a statistically significant difference in the number of abnormal quadriceps tendon of middle and distal segments(P=0.002, P=0.001). The two groups had better consistency in assessing tendon grading by two-dimensional ultrasound, the control group(k=0.794, k=0.851, k=0.726), and the RA active group(k=0.707, k=0.709, k=0.703); The two groups were moderately consistent of grading of tendon of the proximal segments by UE, the control group(k=0.576), and the RA active group(k=0.574). The two groups had better consistency in the middle and distal segments of the tendon, the control group(k=0.739, k=0.717), and the RA active group(k=0.710, k=0.723). Conclusion: UE is useful in evaluating middle and distal segments quadriceps tendon injury in active RA patients; UE can provide quadriceps tendon stiffness information of RA active period, which can be used as a supplementary examination of two-dimensional ultrasound method.
