		Objective: To investigate MRI features of masses in third ventricle. Materials and Methods: The MRI findings of 48 patients with third ventricular masses were reviewed retrospectively. Forty-six cases were proved by pathology and 2 cases with metastasis which the primary tumors were proved. Results: There were 22 cases third ventricle masses and 26 cases lesions distorting or invading the third ventricle. Based on the angle between tumors and third ventricular wall and whether had clear margin with peritumor tissue could distinguish intraventricular masses and lesions distorting or invading the third ventricle. Most tumors in the third ventricle had age characteristics. The arachnoid cyst, ependymal cyst, choroid plexus papilloma, craniopharyngioma, germ cell tumors and primitive neuroectodermal tumor frequently occurred in children and teenagers. MRI manifestations of different tumors were different, some of them had characteristic manifestations. Conclusion: Magnetic resonance imaging can distinguish between intraventricular masses and lesions distorting or invading the third ventricle. Diagnostic accuracy can be improved by combining with patient’s age and MRI manifestations.

		Objective: To investigate the changes of morphological structures in trigeminal neuralgia(TN) affected trigeminal nerve by using MR to measure the morphology of the cisternal segment of the trigeminal nerve in TN patients and the control group． Methods: Forty-five TN patients and forty-five healthy volunteers were enrolled in this study and scanned by GE 3.0T high resolution MR． Three dimensional time of flight spoiled gradient recalled acquisition(3D-TOF-SPGR) and three dimensional fast imaging employing steady state acquisition(3D-FIESTA) were used to measure morphological structures in cisternal segment of bilateral trigeminal nerve. All images were done postprocessing by reformat software. The length of the cisternal segments of the trigeminal nerve, the maximum cross-sectional areas of the nerves in coronal, axial and sagittal image, the trigeminal-pontine angle, the turn angles of the nerves passing the petrosal bones, and the distance of the neurovascular compression were measured. Then compared and analyzed the measurements and drew the ROC curve by the different ratios of the morphological measurements in the sequence of SPGR and FIESTA between bilateral trigeminal nerve of TN patients and control group. Values with P<0.05 were considered statistically significant. Results: The length of the cisternal segments of the trigeminal nerve, the maximum cross-sectional areas of the nerves in coronal, axial and sagittal image on the symptomatic side were smaller than that on the asymptomatic side and the control group(P<0.05), but the bilateral trigeminal-pontine angle and the turn angles of the nerves passing the petrosal bones had no difference both in patients and the control group(P>0.05). The length of the cisternal segments trigeminal nerve, the maximum cross-sectional areas of the nerves in coronal, axial and sagittal image on the control group were greater than that on the asymptomatic side(P<0.05), the bilateral trigeminal-pontine angle and the turn angles of the nerves passing the petrosal bones in the control group had no difference with the asymptomatic side. In the different ratios of the morphological measurements in these sequence, the different ratios of the maximum cross-sectional areas of the nerves in the coronal of the SPGR sequence had the best diagnosis efficiency. 84.4% of the neurovascular compression point in TN patient was near the nerve root, the mean distance of the neurovascular compression point was (2.124±1.478) mm. Conclusion: Morphometric measurement of MR sequence in the cisternal segment of trigeminal nerve can display the morphology change of trigeminal nerve more intuitively, increase the objectivity of the clinical TN diagnosis and provides a new method and sight for the diagnosis of TN.

		LIN Ya-nan, CHENG Jing-liang, ZHANG Yong, YANG Lu, ZHAO Shan-shan, ZHANG Xiao-nan
		Objective: To detect the change of diffusion parameter in remote regions of the infarct core after middle cerebral artery occlusion(MACO) in rats using diffusion tensor imaging(DTI), to detect the RGMa protein expression of the brain tissue by immunohistochemistry, and to detect the diffusion and pathological changes of the cerebral infarction core area and bilateral cerebellar hemispheres, and to further understand the relevant mechanism of crossed cerebellar diaschisis(CCD). Methods: All the animals were randomly divided into experimental group(n=56) and control group(n=14). After making the successful model, the control group and the experimental group rats underwent MRI at 1 h, 3 h, 6 h, 9 h, 12 h, 24 h and 72 h, and the expression of RGMa protein was detected by immunohistochemistry in the bilateral cerebellar hemispheres of rats. Results: The results of MRI in the experimental group at each time point after MCAO in rats showed that the FA values were all decreased in the bilateral cerebellar hemisphere compared with normal control group, and the FA values were decreased to the lowest at 12 h, and the FA value of the contralateral(right) cerebellar hemisphere was significantly lower than that of the ipsilateral(left) cerebellar hemisphere. The results of immunohistochemistry showed that the expressions of RGMa protein were increased in the bilateral cerebellar hemisphere compared with the normal control group, and the expression were increased to the peak at 24 h, and the expression of the contralateral cerebellar hemisphere was significantly higher than that of the ipsilateral cerebellar hemisphere. Conclusion: The MR DTI combined with RGMa protein pathology can be used to detect the phenomenon of CCD after supratentorial cerebral infarction, and to explain the mechanism of CCD.

	245	Application of spectral CT in differential diagnosis of solitary pulmonary nodules or masses
		WANG Li-jie, MA Ji-wen, WANG Yong-li, YU Ying-ying, WEN Zhi
		Objective: To explore the value of spectral CT in differential diagnosis of lung cancer, inflammatory lesions and tuberculosis. Methods: A total of 78 patients with pulmonary nodules or masses were checked by spectral CT. All patients were divided into lung cancer group(38 cases), pulmonary tuberculosis(20 cases) and inflammatory lesions group(20 cases). The monochromatic CT value, iodine concentration(IC), and slope of spectral attenuation curves, normalized iodine concentration(NIC) and normalized water concentration were measured. The one-way ANOVA and Kruskal-Wallis H test were used to analyze parameters among 3 groups． ROC curves were taken to determine the threshold value of the differential diagnosis. Results: The monochromatic CT value, IC, NIC and slope rate of spectral curve among the three groups had statistically significant differences in both phases(all P<0.05). Pairwise comparison between lung cancer and pulmonary tuberculosis, inflammatory lesions and pulmonary tuberculosis were statistically significant(P<0.05), but there was no statistically significant difference between lung cancer and inflammatory lesions(P>0.05). When NIC(venous phase)>0.325 and NIC>0.298, the sensitivity of diagnosing inflammatory lesions and pulmonary tuberculosis, lung cancer and tuberculosis were respectively 95.0％, 97.4％, and the specificity of them were 85.0％, 75.0％ respectively． Conclusion: The quantitative analysis of multiple parameters using spectral CT imaging has great value in the differentiation of lung cancer and pulmonary tuberculosis, and pneumonia and pulmonary tuberculosis, but it can’t be used to differentiate lung cancer and pneumonia.

	250	Pathological features and imaging analysis of solitary fibrous tumors
		CUI Yan-qiu, YU Yong-mei, DOU Tong, GUO Yong
		Objective: To investigate the imaging manifestations and pathological features of solitary fibrous tumors. Methods: The imaging data of 19 cases with solitary fibrous tumor confirmed by pathology were retrospectively analyzed and compared with the corresponding pathological results. Results: ①All of the 19 cases had single lesion, 8 cases occurred in the pleura, 3 in the renal hilum, 2 in the central nervous system, and the wall of the chest, lung, pelvic cavity, neck and shoulders, the back of the lumbar and the submandibular region each had 1 case occurred; One case among them was malignant. The tumors ranged from 3~15 cm in maximum diameter. The tumors were mostly quasi-circular or oval or irregular solid soft tissue masses with clear boundary, some of them were lobulated. ②In the 16 cases of CT examination, 4 lesions showed homogeneous density, 12 lesions showed heterogeneous density, 5 cases of which had calcification; Most of the lesions showed uneven enhancement; The multiphase scanning type is “fast in and slow out”. Three patients underwent MRI. Most of the lesions showed equal or slightly low signal on T1WI, mixed signal on T2WI. The lesions were obviously enhanced on enhanced T1WI. Histologically, the tumor were formed with hyper-and hypo-cellular spindle cells, dense collagenous fibers and thin-walled blood vessels. Conclusion: SFT can occur in many parts of the body and the imaging manifestations have certain characteristics. The final diagnosis still needs pathological and immunohistochemical examination.

	260	Application of virtual unenhanced imaging of dual-source CT in small intestine lesions
		WANG Jun, LI Hui, LIU Yan, WANG Jia
		Objective: To explore the application of dual-source CT virtual scan in the small intestine. Methods: Thirty-five patients underwent small intestine radiography with dual source CT, a total of three scans, namely conventional unenhanced, arterial and venous phase. The virtual unenhanced images were obtained and compared with the real images in arterial and venous phase. The subjective score of image quality was evaluated by two doctors using double-blind method, the objective score of image quality was to select the region of interest in the images of three sequences, to record the average CT values of lesions, liver, muscle and fat of virtual unenhanced and real images in arterial and venous phase, and the noise generated by the machine, lesion-noise ratio(SNR) and contrast-noise ratio(CNR). At the same time, the total radiation dose of three phase scans and the total radiation dose of arterial and venous enhancement after the removal of the unenhanced dose were recorded. ANOVA was used to compare the average CT values of the images of two groups, SNR and CNR. Two independent samples t-test was used to analyze radiation dose. Results: In 35 patients, there were 16 males, and 19 females, aged 27~83 years old, which had no obvious abnormalities in 16 cases, chronic colitis in 3 cases, 4 cases of intestinal obstruction, 2 cases of tumor resection, intestinal polyp in 3 cases, 2 cases of lipoma, 3 cases of colon cancer, 1 case of mesenteric fibroma, ileocecal tumor in 1 case. Using SPSS 21.0 software for statistical analysis, the CT values of lesions, fat, muscle of virtrual non-contrasted(VNC) were less than the those of true non-contrasted(TNC), the difference was statistically significant, while the CT value of VNC of liver was greater than that of TNC, the difference was statistically significant. Virtual unenhanced SD was lower than the real plain, and SNR, CNR were higher than those of the real plain, the difference was not statistically significant. The subjective scores of the three images could meet the diagnostic requirements, although virtual unenhanced subjective rating was lower than that of real plain, but the difference was not statistically significant, high-quality image rate of 71.8%. The dual-energy two phases radiation dose was less than 24.8% of the conventional three phases radiation dose. Conclusions: In the examination of patients with small bowel radiography, the dual-energy CT VNC images can be used as a benchmark for the density measurement and an alternative for the traditional plain, eliminating the conventional pre-enhancement scan, greatly reducing the patient’s radiation dose.

		ZHANG Li-ou, SUN Hong-zan, LU Zai-ming
		Objective: To investigate the value of 18F-FDG PET/CT imaging in the diagnosis of retroperitoneal fibrosis. Materials and Methods: A retrospective analysis of 18 cases with retroperitoneal fibrosis from January 2013 to October 2016 confirmed by imaging examination with clinical follow-up of more than one year(10 cases) and pathology(8 cases) was performed, including 7 cases in the active phase and 11 cases in the inactive phase with evidence from serum laboratory findings(obviously hige C reactive protein and erythrocyte sedimentation rate). Results: The CT images of 18 patients showed irregular soft tissue masses in retroperitoneum, with unclear boundaries often involving the abdominal aorta, iliac artery, ureter and so on. Five of the 7 patients in the active phase were initially diagnosed, with increased FDG uptake in the masses on PET images. The rest 2 patients had already begun their steroid treatment since 2 and 2.5 months ago respectively, with no significant increase in FDG metabolism on PET images. In the 11 patients with inactive retroperitoneal masses which were initially diagnosed, the FDG metabolism varied. Conclusion: 18F-FDG PET/CT can clearly show the range of retroperitoneal fibrosis by CT, and FDG metabolism on PET is helpful to determine whether the lesion is in the active phase and to evaluate the effect of steroid treatment.

	268	The value of uterine arteries hemodynamic indexes in predicting adverse outcomes of pregnancy-induced hypertension
		WANG Ya-yun1, SU Hai-li2, TUO Sheng-jun1, YU Ming1, LIU Zhi-ling1, QIAO Yuan3, CHEN Xiao-yuan3
		Objective: To discuss the value of the clinical data and hemodynamic indexes of uterine arteries in predicting adverse outcomes in patients with pregnancy-induced hypertension(PIH). Methods: Eighty-seven PIH patients in second-third trimester complicated with fully follow-up materials were chosen for this study. The general clinical data were recorded. A series of dynamics indexes of uterine artery were detected by conventional abdominal ultrasound. All the patients were followed-up through the whole pregnant period. Eclampsia, fetal distress in uterus and early pregnancy termination were recorded as the adverse outcomes. The patients were divided into benign group and adverse group based on the outcomes. Results: Sixty-three PIH patients(72.4%) presented adverse outcomes during the followed-up period. The proportion of severe preeclampsia in adverse group increased significantly compared with the benign group(58.7% vs 20.8%, P=0.003). In adverse group, patients were more likely to have the early diastolic notch in both sides of uterine arteries compared to the patients in begin group(39.7% vs 16.7%, P=0.042). The PI, RI and S/D values of uterine artery were increased significantly in PIH patients presented adverse outcomes in late pregnancy(P<0.05). When the cut-off value of PI was 0.97, the sensitivity and specificity of predicting adverse outcomes were 50.8% and 83.8% respectively. When the cut-off value of RI was 0.51, the sensitivity and specificity of predicting adverse outcomes were 63.5% and 70.8% respectively; When the cut-off value of S/D was 2.1, the sensitivity and specificity of predicting adverse outcomes were 65.1% and 70.8% respectively. The multinomial logistic regression analysis showed that RI>0.51 was the independent predictive factor of adverse outcomes of PIH patients(OR=4.224, P=0.006). Conclusions: PIH can cause multiple hemodynamic changes. Hemodynamic changes of the uterine arteries which could be assessed by ultrasound has certain significance for the prognosis of PIH, and our study suggests that the RI could be the independent predictive factor of adverse pregnancy outcomes.

	291	Perioperative effects of radiofrequency ablation in the treatment of hepatic malignancies under the guidance of laparoscopic ultrasound and percutaneous ultrasound
		GAO Nan, MU Pei-yuan, BAI Yuan-yuan, ZHOU Ning-xin
		Objective: To investigate the perioperative effects of radiofrequency ablation in the treatment of hepatic malignancies under the guidance of laparoscopic ultrasound and percutaneous ultrasound. Materials and Methods: A total of 66 patients with 85 lesions were divided into two groups(n=33), and treated with laparoscopic ultrasound-guided and percutaneous ultrasound-guided radiofrequency ablation. To get evaluation of perioperative effects preliminarily, all patients were followed up with ultrasonography and blood tests, etc. Results: Two groups of patients were successfully completed ultrasound-guided radiofrequency ablation. The amount of bleeding, operative time, postoperative hospital stay, total hospital stays and liver injury of the percutaneous ultrasound group were less than those of the laparoscopic ultrasound group(P<0.05). Laparoscopic ultrasound identified 5 new lesions(11.63%) missed at preoperative imaging(0.5~1.5 cm), and intraoperative 45.45%(15/33) of the patients combined with other resection, while 88.37%(38/43) lesions adjacent to the vital organs. Also, the postoperative complications were less than percutaneous ultrasound group. Only a little color signal was shown in ten lesions of percutaneous ultrasound group, while color Doppler flow imaging showed no color signal in other patients of both groups. In the perioperative period, the transaminase was increased transiently, laboratory studies demonstrated that it decreased to normal range finally, and no severe complications occurred. Conclusion: By laparoscopic ultrasound and percutaneous ultrasound, the lesions can be located accurately and the ablation zone can be visualized in real-time. The application of laparoscopic ultrasound could not only get satisfied effects in perioperative period, but also broaden the application scope of radiofrequency ablation. With the development of ultrasound-guided technique, laparoscopic ultrasound will play a significant role in minimally invasive surgery.
