LIU Ya-bao1, JI Sheng-zhang2, ZHANG Bo-sheng1, JIA Fu-yan1
Objective: Through using multi sequence high resolution 3.0T MRI, classifying the carotid plaque, measuring plaque burden and analyzing its composition, to investigate the correlation of carotid artery plaque typing, carotid artery plaque burden and acute cerebral infarction. Methods: We enrolled sixty-five patients who had acute cerebral infarction to have MRI examination for head and bilateral carotid arteries within seven days through using Philips Intera Achieva 3.0T MRI(the skull sequences include T1WI, T2WI, FLAIR and DWI. Carotid arteries sequences include T1WI, T2WI, 3D time of fight and MP RAGE). Then we measured the volume of acute cerebral infarction in DWI. According to the MRI classification criteria of the artery plaque established by Cai Jianming etc, we used the software of CASCADE to classify the plaque and analyze its composition, measure the lumen area of carotid artery and total vascular area, calculate the WA and NWI, measure the lipid core volume in carotid plaque. Results: ①The incidence of carotid artery Ⅳ~Ⅴ and Ⅵ type plaque and the lipid core in plaque, the average tube wall area, the NWI of ischemic side carotid artery wall, all items of them were higher than that of non ischemic side. The difference was statistically significant(P<0.05). ②The NWI of carotid artery in ischemic side and the lipid core volume with the volume of acute cerebral infarction on the same side have strong positive correlations(P<0.05). Conclusion: The carotid atherosclerotic plaque is closely related to the occurrence of acute cerebral infarction. Through the 3.0T MR, the images displayed perfectly the composition of carotid plaque, carotid artery plaque typing, the quantitative measurement of carotid artery wall burden and the volume of the interior plaque component. Consequently, providing assistance to predict the occurrence of cerebral ischemia and monitor the development of the illness.

Objective: To investigate the CT findings of thoracic solitary fibrous tumors(SFT). Methods: CT images of 25 patients with thoracic SFT confirmed by surgery and pathology were retrospectively analyzed. Results: All cases had single lesion. Twenty-three lesions originated from the pleura, 2 lesions from the lung. The mean diameter of the 25 lesions is 10.9 cm on CT images. All lesions presented as round or oval with well-defined margins, in which 10 cases(10/25) were lobulated, 4 cases(4/25) had calcification. On plain CT, heterogeneous density was showed in 6 cases(6/9), and homogenous isodensity was showed in 3 cases(3/9). On contrast enhanced CT, unevenly moderate or intensive enhancement presented as “geographic pattern” was demonstrated in 15 cases(15/21). Disorganized vessels with obvious enhancement were showed in 14 masses during arterial phase. Multiple nodular enhancement was seen in 8 masses, pathy and cystic non-enhancement areas were seen in 13 cases. There are significant differences in some CT findings between different size of SFT(P＜0.05). Conclusion: Thoracic SFT usually presents as single, huge mass with well-defined margins and contains various components. Multiple nodular enhancement and inner vessels in disorder are the characteristics of thoracic SFT on contrast-enhanced CT images.

GAO Si-zhe1, MA Yue1, HOU Yang1, ZHANG Xiao-juan2
Objective: To investigate the clinical value of IMR technique in 256 slice prospective coronary CTA with low dose and low Iodine load. Methods: One hundred patients who would perform coronary CTA were enrolled and the patients were divided into two groups randomly. All the patients were performed prospective CTA. Patients in group A were performed CTA by using normal tube voltage(120 kV), dose right index(DRI)=15 was considered to be currents and iDose4 reconstruction. Patients in group B were performed CTA by using low tube voltage(100 kV), DRI=11 was considered to be currents and IMR reconstruction. The injection protocols of group A and group B were 0.8 mL/kg and 0.6 mL/kg, respectively. The injection time was 12 seconds. Quantitative measurements of CT value, image noise, signal-to-noise(SNR) and contrast-to-noise(CNR) were measured in each group. t-test was used for comparisons of objective evaluation, indices(noise, SNR, CNR), radiation dose(CTDIvol, DLP, ED) and Iodine load between the two groups. Mann-Whitney U test was used for comparisons of subjective evaluation of IQ between the two groups. A level of P＜0.05 was considered statistically significant. Results: There were significant differences in SD between group A(34.3±4.3) HU and group B(23.4±2.8) HU(t=14.977, P=0.000). There were significant differences in SNR between group A(11.9±1.9) and group B(16.3±2.2)(t=-10.713, P=0.000). There were significant differences in CNR between group A(15.1±2.3) and group B(21.1±2.7)(t=-12.083, P=0.000). Group B showed the better objective data. Compared with group A, there were significant differences in subjective noise and acceptability of images(U=951.000, 934.000, P=0.008, 0.005). There were no significant differences in image contrast and image sharpness(U=1 233.000, 1 233.500, P=0.884, 0.888). The effective dose(ED) of group B (0.94±0.23) mSv was 39% lower than that of group A (1.53±0.32) mSv. The Iodine load of group B (15.1±2.4) g was 25% lower than that of group A (20.1±2.5) g. Conclusion: Compared with iDose4, using 256 MDCT, iterative model reconstruction technique can provide 39% ED and 25% Iodine load reduction, while the images could still satisfy the requirement of diagnosis.

ZHAO Fei1, LIU Yi1, DONG Jian2
Objective: To investigate the clinical value of indirect CT venography(CTV) in varicose veins(VV) of lower limbs. Methods: This retrospective study has been approved by the hospital institutional review board. Thirty-seven patients（F/M, 21/16, age range 29~65 years) diagnosed as VV were recruited in this study, and they were performed with indirect CTV in lower limbs. Two radiologists reviewed all the images, including axial, MPR and 3D volume rendering(VR). Quantitative indexes were compared, including signal intensity(SI) of great saphenous vein(GSV) and VV, the signal-to-noise ratio(SNR) and contrast-to-noise ratio(CNR). While subjective indexes were performed with a 3-point scale. Perforator veins larger than 2 mm were marked, and statistical analysis was performed. Results: All GSV were demonstrated in 37 patients, including 23 unilateral and 14 bilateral VV. Quantitative indexes demonstrate no statistical significance between the proximal point in GSV and VV, including SI, SNR and CNR(119±17.2 vs. 123.4±21.4), (9.31±2.68 vs. 9.52±3.22), (3.98±1.99 vs. 4.06±2.17), respectively. For subjective image quality, 27(73.0%) were excellent, 9(24.3%) fair and 1(2.7%) poor. Fourteen perforator veins were detected, and the mean diameter of perforator veins marked by CTV was (2.97±0.92) mm, which were ligated during the surgery thereafter. Conclusion: Indirect CTV demonstrates feasibility in diagnosis of VV in lower extremities, especially for perforating veins, which is important for preoperative assessment.

MA Sui-hong, LIU Jian-hua, YANG Yu-wen, WEI Hong-qin, XIAO Shu-yi, HU Zhi-wen
Objective: This paper aims at using color Doppler flow imaging(CDFI) and pulse wave(PW) spectrum analysis technology to observe the blood flow of canals pyloricus and the blood flow rate and so on in congenital hypertrophic pyloric stenosis(CHPS), objective to investigate the clinical significance and value of Doppler ultrasonography in the diagnosis and assessment of CHPS. Method: The study enrolled 65 cases of CHPS infants and 50 infants without CHPS served as control group. CDFI was done to reveal the distribution feature of blood flow in each layer of the pyloric mucosal canals and the blood flow grade of muscular layer and mucosal layer. PW was done to measure the blood flow rate and frequency analysis. In addition, the muscle layer of CHPS group was divided into 3 groups according to the thickness, and the relationship between the thickness of the muscle layer and the parameters mentioned above was compared. Results: The distribution feature of blood flow in each layer of pyloric canal mucosa was observed clearly by CDFI examination in the CHPS group. The mean grade of flow in the muscular layer was 2.83±0.38. The blood flow maximal velocity(Vmax) of muscular layer was (16.96±0.91) cm/s, and the resistance index(RI) was 0.68±0.33. The thickness of muscle layer in 65 CHPS was positively related to age, weight, diameter of pyloric canal, Vmax and RI, there was no correlation with pyloric tube length. There was no significant difference between the first groups and the second groups in blood flow classification, Vmax and RI, and the blood flow was more abundant. The blood flow of the third groups was lower, and the rate of Vmax and RI increased. Conclusion: CDFI combined with color Doppler artifacts technique is proved to be effective to observe the distribution feature and blood flow grade in each layer of pyloric canal in CHPS patients. Vmax and RI are used to estimate the severity of pyloric stenosis. This method provides the evidence for judging the degree of pyloric stenosis clinically, and furnishes the basis of therapy along with its clinical significance and good application value.

LIU Yan, BO Gen-ji
Objective: To investigate the value of diagnosis for clinically significant prostate cancer(sPCa) by combining bi-parametric magnetic resonance imaging(B-MRI) with prostate specific antigen density(PSAD) on the basis of the prostate imaging reporting and data system verison 2.0(PI-RADS V2). Methods: Eighty of prostate cancer, 47 patients of benign prostate hyperplasia(BPH) and 4 of prostatitis that were confirmed by biopsy pathology in our hospital were scanned with 3.0T B-MRI(T2WI and DWI). Two diagnostic physicians respectively assessed examination by using the PI-RADS V2 score, double-blinded to the indication for the MR imaging. All of the results were recorded. To collect the value of prostate specific antigen(PSA), prostate volume and to calculate the value of PSAD. Using the pathological results as the golden standard, the data of different group were analyzed using method of statistics. Results: The average values of PSAD and PI-RADS V2 score were 1.19±0.88, 3.90±1.00 in PCa group and 0.38±0.40, 2.30±0.55 in non-PCa group respectively. The difference of two groups were statistically significant(PSAD, t=10.10, P<0.05; PI-RADS, t=5.91, P<0.05). The area under ROC curve for PSAD and PI-RADS V2 were 0.794, 0.894. The diagnostic sensitivity was 98.68%, the specificity was 30%, the positive predictive value(PPV) was 68.18%, the negative predictive value(NPV) was 94.12% for sPCa with the cutoff point 0.15 of the PSAD. The diagnostic sensitivity was 90.67%, the specificity was 69.23%, the PPV was 81.00%, the NPV was 83.72% for sPCa with the cutoff point 0.15 of the PI-RADS V2. When PI-RADS V2 score and PSAD combined, a PI-RADS V2 score of 3 and PSAD≥0.15, or PI-RADS V2 score≥4 and PSAD≥0.15, the detection of sPCa were 72%, 92%. When a PI-RADS V2 score<3 and PSAD≥0.15, or PI-RADS V2 score≥4 and PSAD<0.15, the detection of sPCa were 20%, 25%. In contrast, when a PI-RADS V2 score≤3 and PSAD<0.15, there was no sPCa detected. Conclusion: It is very useful to predict biopsy outcome and provides even more accuracy in detecting clinically sPCa when combining B-MRI PI-RADS V2 with PSAD. Patients with a PI-RADS V2 score of ≤3 and PSA density of <0.15 may avoid unnecessary biopsies.
