	381	Imaging features and pathological analysis of the intracranial solitary fibrous tumor
		WANG Chao, WANG Xiao-ming
		Objective: To investigate the imaging and pathological characteristics of primary intracranial solitary fibrous tumor(ISFT). Methods: Eight patients with primary ISFT received operation in our hospital from January 2005 to December 2015. All of the tumors were confirmed by pathology. Six cases received CT scan(4 with enhancement). All the cases underwent gadolinium-enhanced MR. Results: The main clinical symptom was headache(5/8). All the 8 tumors were single, and most origined from supratentorial(6/8), close to the meninges. Diameter of the tumors ranged from 3～7 cm(4.5 cm on average). And the tumors are lobulated, round or irregular in shape. CT scan showed the tumors were mainly mixed cystic and solid(4/6). Varicose veins were visible within tumors with heterogeneous enhancement. MR scan showed clear margin, with or without mild peritumoral edema in most cases(5/8). T1WI showed the signal was mainly isointense to the white matter. T2WI showed the signal of tumors was heterogeneous, with clear boundary between high and low signal(5/8). Contrast-enhanced T1WI showed marked heterogeneous enhancement, and some of the foci of low T2WI signal intensities showed enhancement(4/8). Pathological results showed the tumor cells were mainly spindle shaped, with varying arrangement, and the area with densely or loosely arranged cells appeared alternately. Blood vessels were rich in the stroma, and collagen and myxoid were visible. Immunohistochemical results showed Vimentin was diffusely positive(8/8). CD34 was positive in 7 tumors, Bcl-2 in 6 and Ki-67 ranged 5%～20%. Pathology showed 4 were benign, 2 were low-grade malignant and 2 were borderline. Conclusion: ISFT is solitary, clearly marginal, supratentorial origined, and closely related to the meninges. Most of them are mixed cystic and solid, with significantly heterogeneous enhancement. The “yin and yang” sign and enhancement of low signal area in T2WI are characteristic. The diagnosis of ISFT should not only depend on the imaging. The combination of imaging, pathology and immunohistochemistry is necessary. In addition, some benign tumors may relapse, so it should be followed up regularly.

		SHANG Jin, LIU Yang-ying-qiu, WANG Wei-wei, SONG Qing-wei, MIAO Yan-wei
		Objective: To explore the imaging features of enlarged perivascular spaces(EPVS) in basal ganglia and centrum semiovale in mild cognitive impairment(MCI) and Alzheimer disease(AD) patients, and to analyze the relationship between EPVS and cognitive impairment． Methods: In this study, 30 patients with AD(AD group, mini-mental state examination(MMSE)<24), 20 patients with MCI(MCI group, 24≤MMSE<27) and 30 normal controls(NC group, MMSE≥27) were reviewed retrospectively. EPVS in both the basal ganglia and centrum semiovale were counted in axial images according to the following standard: 1 score for EPVS less than 10, 2 scores for EPVS between 11 to 20, 3 scores for EPVS between 21 to 40 and 4 scores for EPVS more than 40. Kruskal-Wallis test and Kolmogorov-Smirnov Z test were used to analyze the inter-group difference. Relationship between the scores of EPVS and MMSE was explored using Spearman’s correlation analyses. Results: Significantly statistical differences of EVPS score in both the basal ganglia and centrum semiovale were found among the three groups(H values respectively=26.45, 41.4, all P<0.01). In the basal ganglia, EPVS score in AD group(1.80±0.71) was higher than that in NC group(1.06±0.25)(P＜0.01), and there was no difference of EPVS scores between MCI and NC group(P>0.05). In the centrum semiovale, EPVS scores in AD group(2.93±0.83) was obviously higher than that in MCI group(2.40±0.68) and NC group(1.40±0.50, P＜0.01). There were correlations between the scores of EPVS and MMSE in both the basal ganglia and centrum semiovale(r values respectively=-0.708, -0.594, all P<0.01). Besides, in the NC group, there was correlation between the score of EPVS and MMSE in the basal ganglia(r=0.418, P＜0.05）. Conclusion: In patients with AD, EPVS is a common phenomenon in both the basal ganglia and centrum semiovale, and it can help to evaluate the changes of cognitive abilities.

		Objective: To study the MRI features of cerebral paragonimiasis and to assess the value of MRI in the diagnosis of this disease. Methods: Six cases with a positive antibody test of cerebral paragonimiasis were included in the study. Conventional MRI was performed with spin echo pulse sequence, DWI and Gd-DTPA enhancement for all the cases. MRI features and the pathogenesis of cerebral paragonimiasis were retrospectively analyzed. Results: The age of the 6 cases were between 9 and 20 years old. There were 20 lesions in the 6 cases totally, with 19 lesions in the cerebrum and 1 in the basal ganglia region. MRI revealed conglomerated round cysts and edematous area. The cysts had rim of high signal on T1WI, caused by hemorrhage. There were characteristic “tunnel sign” in all the 6 cases. In the Gd-DTPA enhanced images, 5 cases showed patchy or nodular enhancement, and 1 case showed meningeal enhancement. Conclusion: The clinical features of cerebral paragonimiasis are various and diverse, and it often developes in children and adolescents. MRI features of cerebral paragonimiasis are relatively typical. The signal due to hemorrhage and “tunnel sign” are characteristic. MRI is of important value in the diagnosis of the disease.

	397	Differentiation of 2.0～4.0 mm benign small thyroid nodules from malignant ones by ultrasound
		LIU Shu-yu1, GU Ying2, HAN Zhi-jiang2, WANG Yan1
		Objective: To investigate the diagnostic value of ultrasound for differentiating 2.0～4.0 mm benign small thyroid nodules from malignant ones. Methods: Ultrasonic data of 412 small thyroid nodules with maximum diameter of 2.0～4.0 mm, collected from 359 cases by operation and pathology, were analyzed retrospectively, including 173 cases of papillary thyroid microcarcinoma(PTMC, 194 nodules), 179 cases of micronodular goiter(MNG, 204 nodules) and 7 cases of PTMC(7 nodules) and MNG(7 nodules). Morphology, low echo, aspect ratio≥1 and distribution of micro-calcification in PTMC and MNG were observed. Results: Statistical differences were found in irregular morphology, low echo and aspect ratio≥1(χ2=261.967, P＜0.05; χ2=17.259, P＜0.05; χ2=249.703, P＜0.05) between 2.0～4.0 mm nodules of PTMC and MNG, but no difference was found in micro-calcification(χ2=1.155, P＞0.05). Aspect ratio≥1 had the highest specificity(92.9%), positive predictive value(91.9%) and accuracy(88.8%). Irregular morphology had the highest negative predictive value(94.4%). Low echo had the highest sensitivity(97.0%) and lowest specificity(14.7%). Conclusions: Irregular morphology and aspect ratio≥1 are the two important signs for differential diagnosis of 2.0～4.0 mm PTMC from MNG. Although low echo has a high sensitivity for PTMC, its low specificity limits clinical application.

		Objective: To observe the short-term efficacy for celecoxib as a sensitization agent for 125I particles implantation in the treatment of lung cancer. Methods: Sixty-six patients with lung cancer were treated by CT guided interstitial 125I particles implantation． They were randomly divided into two groups(33 patients in test group, the other 33 in control group). The test group was given celecoxib on the same day of 125I particles implantation. The control group was only implanted with 125I particles. The local control of the tumor(complete relief+partial relief) was used as an evaluation standard of curative effect. Results: Among the 33 patients in the test group(125I particles implanted with celecoxib as radiotherapy sensitization agent), 3 patients had complete relief, 24 patients had partial relief, 3 patients had no effect and 3 patients had slight relief. The short-term effective rate was 81.8%. In the control group(33 cases with implanted 125I particles only): 1 patient had complete relief, 19 patients had partial relief, 3 patients had slight relief and 3 patients had no effect. The recent effective rate was 60.6%. The difference between the two groups was statistically significant(P<0.05). Conclusion: The treatment of celecoxib combined with 125I particles implantation for lung cancer has good radiotherapy sensitization effect. It improves the local control rate of tumor and has fewer side effects and is safe and effective.

		Objective: To evaluate the global myocardial circumferential strain and strain rate in rabbits with acute and chronic myocardial infarction by two-dimensional speckle tracking imaging. Methods: Twenty New Zealand rabbits with ligation of the left circumflex artery were observed as experimental group and 5 rabbits without ligation of the artery as control group. The degree of global myocardial circumferential strain(GCS) and strain rate(GSrC) at mitral valve, papillary muscle and apical level were compared by speckle tracking imaging before, one week and seven weeks after surgery, respectively. And the fate of the animals, cardiac magnetic resonance imaging(cMRI) and triphenyltetrazolium chloride(TTC) staining were studied for myocardial infarction sizes(MI size%). Results: Compared with the preoperative parameters, there were significant increases in GCS and GSrC one week after the surgery(P<0.05) at mitral valve level. Compared with those parameters 1 week postoperative, there were significant decreases in GCS and GSrC at the 7th week postoperative(P<0.05), which had no obvious changes than those of the basic status. Compared with the preoperative parameters, there were significant decreases in GCS and GSrC at the 1st and 7th week postoperative at papillary muscle and apical level(P<0.05), but there was no significant difference between the 1st and the 7th week postoperative. Conversely there were no much changes of the degree of GCS and GSrC of myocardium at each time point in the control group(P>0.05). The degree of GCS and GSrC of myocardium at papillary muscle level had correlations with LVEF(US), LVEF(cMRI) and MI size%(r=-0.943, -0.916, -0.749, -0.615, 0.807, 0.641, respectively, all P<0.05). Conclusion: Two-dimensional speckle tracking imaging can objectively quantify regional and global heart function in rabbits, and can help to analyze the location and size of the myocardial infarction.

		LIU Xiao-dong, LIU Ai-lian, LIU Jing-hong, LIU Yi-jun, SUN Mei-yu, LI Ye, ZHAO Ying, FANG Xin, YUAN Gang
		Objective: To explore the effect of sampling interval on normal gastric perfusion by revolution CT. Methods: Twenty-eight volunteers without gastric disease were studied using revolution CT scanner. Fourteen volunteers(group A) were scanned with standard continuous perfusion, and other volunteers(group B) were scanned with intermittent perfusion. Two groups of perfusion scanning were performed with axial scan mode and Z axis coverage of 160 mm. Group A collected perfusion images 25 times with sampling intervals of 2 s(exposure time of 0.5 s, interval time of 1.5 s), and the total scan time was 50 s. Group B obtained arterial phase image with spiral scanning mode at 15 s after 8 times perfusion. The conversion time from helical to axial scan mode and exposure time was about 12～16.2 s. And then another 13 times of perfusion data were collected, with a total scan time of 50～54.2 s. Three regions of interest were placed in gastric wall of greater and lesser curvature. The acquired data were used for calculation and analysis by a CT perfusion software package to measure 8 parameters: blood flow(BF), blood volume(BV), mean transit time (MTT), time to peak(TP), positive enhancement integral(PEI), mean slope of interest(MSI), IRF and Tmax. Radiation dosage was also collected. Perfusion parameters in the greater and lesser curvature of stomach in different groups were compared. Result: BV((12.83±4.30), (18.44±4.39) mL/(min·100 g)) and BF((61.54±10.13), (64.99±13.77) mL/100 g) in the greater curvature were statistically higher than those of lesser curvature both in group A and B, with P values of 0.027, 0.004, 0.002 and 0.000. But the rest perfusion parameters(MTT, TP, MSI, PEI, IRF, Tmax) didn’t show significant difference. Between the two groups of BV and PEI in the greater and lesser curvature, differences were statistically significant(P=0.002, 0.004, 0.017, 0.032). And only in the lesser curvature there was a significant difference for MTT and Tmax, but no significant difference was found in the greater curvature. Values of group A were lower than those in group B. And there were no difference for BF, TP, MSI and IRF between two groups. Effect dosage of intermittent perfusion was reduced by 15.41% compared with continuous perfusion. Conclusion: Sampling interval of gastric perfusion on revolution CT has an effect on BV, MTT, PEI and Tmax perfusion parameters, but not on BF, TP, MSI and IRF values. BV and BF values are different between greater curvature and lesser curvature.

		LI Zhen-hui, ZHANG Zhi-ping, DONG Xing-xiang, YANG Guang-jun, GAO De-pei, ZHANG Da-fu
		Objective: To explore the CT findings of primary colorectal neuroendocrine carcinomas(NECs), and to improve the imaging diagnosis of them. Methods: CT findings of 32 patients with primary colorectal NECs and 46 patients with colorectal adenocarcinoma confirmed by surgery and pathology were analyzed retrospectively. The differences of age, gender, tumor location, size of the lesion, the thickening pattern of the intestinal wall, the pattern of contrast-enhancement, the peri-intestinal invasion, the occurrence of intestinal obstruction and metastasis to other organs were compared between the two groups. Results: Compared with the colorectal adenocarcinoma group, patient of colorectal NECs group was younger(t=3.634, P<0.001). There were statistically significant differences of focal thickening, size of the lesion and contrast-enhancement(P<0.05). While in gender, lesion location, occurrence of intestinal obstruction, lymph node metastasis, or metastasis, there was no statistically significant difference(P>0.05). Conclusion: Primary colorectal NECs are often found in young patients. Their CT manifestations include a polypoid lesion and is characterized by significant contrast-enhancement. Significantly contrast-enhanced metastasis may occur in liver.

		WEI Wei, WANG Hong, LI Guo-jing, GUO Qiu-yun, DING Gui-chun, WANG Jian-hua
		Objective: To investigate the value of ultrasound in diagnosis of placental abnormalities and the outcomes of pregnancy. Methods: Ultrasound images of 126 cases of postnatally confirmed placental abnormalities were analyzed retrospectively. Two hundred and four others were randomly selected from the normal group as control. Rate of preterm birth, birth defects and neonatal weight were analyzed. Relationship between pregnancy outcome and placental abnormalities was also analyzed. Results: Confirmed by delivery or caesarean section, there were a total of 126 cases of placental abnormalities, with 57 cases of placenta previa, 4 cases of placenta implantation alone, 15 cases of placenta previa complicated with placenta implantation, 43 cases of abnormal placental shape, 4 cases of placenta neoplasm and 3 cases of placental abruption. Ultrasound diagnosis was correct in 117 cases, with the diagnosis accuracy of 92.8%. The difference of low birth weight between the two groups was statistically significant. Conclusion: Severe placental abnormalities result in undesirable pregnancy outcomes. Accuracy of prenatal ultrasound diagnosis for placental position and shape is high. The detection rate of placenta previa combined with placenta implantation is higher than simple placenta accreta. The placental abnormality of the back wall of uterus is more easily to be missed.
