229 A study of grey and white matters in temporal lobe epilepsy patients by using VBM-DARTEL and the correlation with executive function
GUO Dan-ni, GAO Yu-jun, LI Ya-ping, ZHENG Jin-ou
Objective: To measure the volumetric changes of grey and white matters in patients with temporal lobe epilepsy(TLE) using voxel-based morphometry-diffeomorphic anatomical registration through exponential lie algebra(VBM-DARTEL) and to study its relationship with the executive function. Methods: Sixteen left-sided temporal lobe epilepsy(lTLE) patients, 26 right-sided temporal lobe epilepsy(rTLE) patients and 38 healthy controls(HC) underwent routine MRI scanning and acquisition 3D fast gradient echo T1 weighted imaging. The VBM-DARTEL method was used to calculate grey matter and white matter volume values after segmentation, and the brain regions with statistical difference were obtained(P<0.001, uncorrected, K≥50), the attention network test was used to evaluate the executive function, and the relationship between the volume value of grey matter and white matter and executive function was studied. Results: TLE patients had diffuse cerebral atrophy, grey matter atrophy of brain regions was mainly in temporal lobe and frontal lobe. The white matter was mainly in temporal lobe and hippocampus, the right anterior lobe of grey matter in rTLE patients was less than that in lTLE patients, no grey and white matter volume increased, compared to HC, the TLE patients’ executive network efficiency values were significantly increased(P<0.05), and executive network efficiency values of the lTLE patients were significantly higher than that of the rTLE patients(P<0.05), and executive network efficiency values were negatively correlated with grey matter volumes in rTLE patients. Conclusion: There are changes in brain structure of the TLE patients. There were differences in the structure and function of patients with different origin lesions. In rTLE patients, the decrease in the volume of grey matters have led to a decline in executive function.

Objective: To investigate the component analysis and display ability of atherosclerotic plaque in the M1 segment of middle cerebral artery by high-resolution MR imaging(HR-MRI) using different sequences, so as to facilitate sequence optimization and diagnosis. Methods: Forty cases of atherosclerotic stenosis in M1 segment of middle cerebral artery were enrolled from September 2015 to December 2016 in our hospital. 3.0T MRI scanner was used to performed the TOF cross section scan, and the location of plaque was determined by 3D-TOF reconstruction, T1WI, T2WI, PDWI and enhanced T1WI were performed perpendicular to the stenotic segment with black-blood MRI technology. The negative and positive cases of lipid core, hemorrhage and calcification of plaque were calculated, and the sensitivity, specificity and K value were analyzed statistically. Results: In 40 cases of atherosclerotic plaque in the M1 segment of middle cerebral artery, there were 32 cases of lipid core plaques, 18 cases of intraplaque hemorrhage, and 22 cases of calcified plaques. Enhanced T1WI that showed lipid core plaques was better, the sensitivity was 100%, specificity was 87.5% and the K value was 0.918. T1WI was the best sequence for demonstrating plaque hemorrhage, the sensitivity was 100%, the specificity was 86.4% and the K value was 0.922. TOF was the best for calcified plaque, the sensitivity was 100%, specificity was 94.4% and the K value was 0.949. Conclusion: Enhanced T1WI has high sensitivity and specificity for displaying lipid core plaques, which is the best display for the lipid core. T1WI and TOF that showed intraplaque hemorrhage was consistent, and TOF could accurately detect plaque calcification. The combination of three sequences of enhanced T1WI, T1WI and TOF can identify the lipid core, hemorrhage and calcification in the plaque.

Objective: To evaluate the changes of left ventricle(LV) energy loss(EL) in patients with obstructive hypertrophic cardiomyopathy(HOCM) after modified morrow procedure by vector flow mapping(VFM), and to analyze the rate of energy dissipation due to blood viscosity from a hemodynamic perspective, and to explore its clinical value in evaluating the operation effect. Methods: The data of four patients with HOCM treated by modified morrow procedure from March 2015 to December 2015 were retrospectively analyzed. Routine echocardiographic parameters were measured before and after surgery, respectively. The standard apical three-chamber dynamic color Doppler images were collected under the VFM mode, and the DSA-RS1 workstation was used for offline analysis, and the EL of LV was calculated frame by frame. The EL mean values of isovolumetric contraction phase, ejection phase, isovolumetric relaxation phase and filling phase were calculated, and the results were the mean values of three cardiac cycles, and the differences were compared before and after the operation. Results: Compared with preoperative condition, echocardiographic parameters: the left ventricular outflow tract(LVOT) diameter and left ventricular end-systolic volume were obviously increased, the LVOT gradient and the thickness of ventricular septum and the proportion of SAM were significantly decreased, the differences were obviously significant(P<0.05). EL value changes: During isovolumetric contraction phase and filling phase, EL mean values were markedly increased in patient 1 and patient 2, markedly decreased in patient 4, and slightly increased in patient 3. During isovolumetric relaxation phase and ejection phase, EL mean values were markedly increased in patient 1 and patient 2 and markedly decreased in patient 3 and patient 4. As a whole the variation trend was that the EL values in patient 1 and patient 2 increased significantly, but decreased significantly in patient 3 and patient 4. Conculsions: After modified morrow procedure, even the normal conditions and echocardiographic parameters were significantly improved in HOCM patients, an increased EL may lead to worse outcomes, EL might be an new index for precise and quantitative assessment of intracardiac blood flow dynamics under different pathophysiology conditions.

NING Hong-xia, BAI Yang, YANG Jun
Objective: To investigate the incidence, clinical features and echocardiographic characteristics of connective tissue disease(CTD) associated with pulmonary hypertention(PH). Methods: The ultrasonic cardiogram data of 1 729 CTD inpatients from June 2014 to December 2016 were collected. According to sPSP≥36 mmHg(1 mmHg≈0.133 kPa), PH patients were screened out and divided into group Ⅰ(sPAP<50 mmHg), group Ⅱ(sPAP: 50 mmHg~<70 mmHg), group Ⅲ (sPAP≥70 mmHg). Clinical and echocardiographic data of 138 suspected CTD-PH were analyzed retrospectively. Results:①The incidence rate of PH in patients with CTD was about 8.0%. MCTD and SSc had the highest incidence of PH(30.8% and 10.5%). ②The incidence rate of pulmonary interstitial fibrosis, Raynaud’s phenomenon and hyperuricemia were increased with the PH degree. ③PAD, RAD1, RAD2, RVD1, RVD2, RVD3 and RVD1/LVD were increased with the PH degree(P<0.05). Compared with former three groups, group Ⅲ had lower LVD1(P<0.05). Compared with control group, group Ⅰ and group Ⅱ had higher LAD, group Ⅰ had higher LVD1(P<0.05). PAD, RAD1, RAD2, RVD1, RVD2, RVD3 and RVD1/LVD2 were positively correlated with the degree of PH(P<0.001). Tricuspid valve regurgitation had the highest incidence of PH, followed by mitral and aortic valve regurgitation. The incidence of valvular stenosis and neoplasm were low. Conclusion: The incidence of PH in subgroups of CTD were different. Echocardiography is an important tool for screening PH patients. CTD-PH have a variety of reasons, we can assess the changes of cardiac structure and functions through echocardiography to identified the reasons.

HAN Jia-yue, SHA Lin, HAN Ning, YU Yang
Objective: To analyze the CT and MRI and clinicopathological features of extrapleural solitary fibrous tumors(ESFT), and to improve the level of recognition and diagnosis of this disease. Methods: Reviewing the literatures in recent years, 11 cases of ESFT confirmed by pathology were retrospectively analyzed, and their clinical, pathological and imaging diagnoses were analyzed and summarized. Results: Among all the eleven cases, 3 cases were in the retroperitoneum, 2 cases in thigh and mediastinum respectively, one in hip, kidney, testis, and pelvis respectively. A total of 13 lesions were detected in 11 cases. All 13 lesions were shown as round or lobulated masses with maximum diameter ranged from 2.5 cm to 24.8 cm. Ten lesions appeared cystic degeneration or necrosis, 1 with calcification on CT, 2 lesions with cystic degeneration or necrosis had low signal on T1WI and mixed signal on T2WI, 9 lesions showed moderate or marked enhancement in arterial phase and delayed enhancement, 4 lesions showed slight enhancement in arterial phase and delayed enhancement, 6 lesions were enhanced to show the surrounding and internal vessels of the focus. Immunohistochemical staining results were shown as follow: bcl-2+(12/12), Vimentin+(9/12), CD34+(11/12), CD117(0/12), SMA(0/12), CK(0/12), S-100(0/12) were all negative. Conclusion: The imaging features of ESFT have a certain diversity, and the prospective diagnosis is not easy. If it is found that the solitary mass with clear boundary, enhanced scan showed continuous or delayed enhancement and see the circuitous vessels, should take into account the tumor, and the definite diagnosis needs to rely on immunohistochemistry.

YANG Li, SHI Gao-feng, LI Yong, ZHOU Tao
Objective: To explore the value of measuring iodine concentration(IC) in perigastric adipose tissue with dual-energy CT(DECT) for judgment of serosa status after neoadjuvant chemotherapy(NAC). Methods: Thirty-four patients with T4 advanced gastric cancer who underwent DECT before and after treatment were enrolled. According to the postoperative pathologic results, the patients were divided into two groups: the down-staging group(n=10) and the non-down-staging group(n=24). IC(ICPAT) and standardized IC(SICPAT) of perigastric adipose tissue were measured in the two groups, respectively. ROC curve was used to evaluate the capability of SICPAT in detecting serosa invasion. Results: Compared with postoperative pathologic results, the accuracy of judgment of serosa status was 70.59% by conventional CT after NAC. The differences of the changes of ICPAT(△ICPAT) and SICPAT(△SICPAT) between the two groups were statistically significant(P＜0.05). With a △SICPAT threshold of 0.095, area under curve(AUC) was 0.908, the sensitivity, specificity and accuracy for detecting serosa invasion were 90.0%, 83.3% and 85.29%, respectively. Conclusion: The SICPAT in perigastric adipose tissue is an effective indicator to determine the serosa status after NAC and to guide the operation time.

Objective: To evaluate the application value of splenorenal shunt in clinical diagnosis and treatment through portal vein imaging by 128 slice spiral CT. Methods: According to the presence of splenic/gastric-renal shunt, 146 patients with liver cirrhosis from December 2014 to January 2016 were divided into two groups: group A and group B. Average diameters of the portal vein, the splenic vein and the left renal vein, and the incidence and severity of esophageal varices in two groups were compared. Results: Forty patients in A, and 106 patients in B. The incidence of splenorenal shunt was about 27.4%. The difference between the two groups in the severity of esophageal varices was statistically significant(χ2=6.24>χ20.05, 2＝5.99, P<0.05). The severity of esophageal varices was significantly correlated with splenorenal shunt(P=0.01<0.05). Conclusion: The splenorenal shunt can reduce the incidence and relieve the severity of esophageal varices. In the operation of portal hypertension, the existing splenorenal shunt can be used to reduce the pressure of the portal vein.
