Objective To analyze the ultrasound examination and computed tomography angiography (CTA) features of carotid web(CAW), and compare with the pathology after carotid endarterectomy, and then compare diagnostic efficacies of the two methods. Methods From June 2018 to July 2019, 159 patients underwent carotid endarterectomy(CEA) in Beijing Tian Tan Hospital were collected, ultrasound examination and CTA were performed preoperatively. The presence or absence of CAW and whether there were thrombosis or atherosclerotic plaques associated with it were identified. The location length, thickness, direction in the lumen, echo characteristics of CAW, and complicated with or without thrombosis or atherosclerotic plaques were recorded. The postoperative specimens were observed, and the pathological analysis was performed. Results Among the 159 cases of CEA, 22 cases were confirmed to have CAW structure by pathology, and HE staining showed extensive intimal fibrohyperplasia and mucoid degeneration, among which 18 cases had plaque formation at the bottom of the carotid web, and 4 cases associated with thrombosis. There were 17 cases of CAW structure diagnosed by ultrasound, 5 cases were misdiagnosed or missed, the sensitivity and specificity of ultrasound in the diagnosis of CAW were 77% (17/22) and 98% (135/137), and the accuracy was 75%. Eleven cases of CAW were diagnosed by preoperative CTA, and 11 cases were misdiagnosed and missed diagnosis, the sensitivity and specificity of CTA in the diagnosis of CAW were 50%(11/22) and 97%(134/137), and the accuracy was 47%. Conclusions The sensitivity of ultrasound in the diagnosis of CAW is higher than that of CTA, which can better display the structure of CAW and whether it is associated with plaque or thrombosis.

Objective To assess the bi-ventricular remodeling in patients with hypertrophic obstructive cardiomyopathy (HOCM) after modified Morrow surgery by three-dimensional speckle tracking echocardiography (3D-STE). Methods Twenty-eight patients with HOCM who underwent modified Morrow surgery from August 2013 to September 2016 in Xijing Hospital were consecutively included in this study. Routine and full-volume echocardiographic images were collected before and after surgery, 3D-STE echocardiographic data were analyzed by TomTec software to calculate left and right ventricular end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV) and ejection fraction (EF), as well as the longitudinal strain(LS), circumferential strain(CS), radial strain(RS) of the 16 segments of left ventricle. The left atrial maximum volume(LAVmax), left atrial minimum volume (LAVmin), left atrial stroke volume(LASV), left atrial ejection fraction(LAEF) were obtained, as well as right ventricular longitudinal strain of septum [RVLS(S)], right ventricular longitudinal strain of free wall[RVLS(FW)], tricuspid annular planesystolic excursion(TAPSE), right ventricular fractional area change(RVFAC). Results Compared with baseline, the IVS thickness were significantly reduced, LVOT pressure gradient were significantly decreased, LVOT diameter were increased significantly (all P<0.05). The LS in the basal part of anterior and lateral wall were increased significantly (all P<0.05). The CS in basal and middle part of lateral wall were increased significantly (all P<0.05). The RS in basal part of anterior, lateral and posterior wall, as well as in the middle part of anterior and lateral wall were increased significantly( all P<0.05). The LAVmax, LAVmin and LASV were decreased, and the LAEF was increased(all P<0.05). The RVLS(FW) and the TAPSE were increased significantly( all P<0.05). Conclusions After modified Morrow surgery in HOCM patients, the morphological remodeling of left ventricle, left atrium and right ventricle are improved, accompanied by the improvement of the function. 3D-STE is valuable in evaluating the efficacy of modified Morrow surgery in HOCM patients.

Objective To explore the characteristics of gallstone-like echo in fetal gallbladder and its changes with gestational age, and following up its prognosis as well as the relationship with bilirubin after birth so as to provide more information for prenatal consultation about neonatal jaundice related diseases. Methods A total of 82 fetuses from January 2014 to December 2017 at Women′s Hospital of Zhejiang University School of Medicine, who had prenatal ultrasound diagnosis and follow-up results with gallstone-like echo in fetal gallbladder, were included in this study. The characteristics of gallstone-like echo in fetal gallbladder were summarized, its change with gestational age, and its association with the status of pregnant mother were analyzed. Bilirubin and the prognosis of the gallstone-like echo were followed up after birth. Results Four different types of prenatal ultrasound characteristics of gallstone-like echo in fetal gallbladder were observed: sediment-like type(n=13), full of hyperechoic type (n=19), multiple hyperechoic type (n=42), and single or scattered hyperechoic type(n=8). Of the total 82 cases, 2 fetus were induced abortion. In the 80 normal-born fetuses, the number of gallstone-like echo were reduced in 9 cases during pregnancy, the gallstone-like echo disappeared in uterus in 8 cases. During the follow up, the gallstone-like echoes disappeared at 3 days, 42 days, 1 year and 2 years after birth in the rest 72 cases, respectively. In the 80 fetuses, 20 cases of neonates with hyperbilirubinemia after birth (4 males and 16 females) including 4 cases of ABO hemolytic, 2 cases of neonatal sepsis.No abnormalities occurred in the remaining 60 neonates during the follow-up period. Conclusions Gallstone-like echo in fetus is a self-limiting disease that occurs in late pregnancy.Some neonates develop hyperbilirubinemia after birth with good prognosis. After phototherapy, the jaundice index decreased to the normal standard and the serum bilirubin content decreased. Key words: Ultrasonography, prenatal; Fetus; Gallbladder; Gallstone-like echo

Objective To explore the mechanism and influencing factors of mirror-image artifact of color blood flow (MACBF) due to longitudinal strong echo big interface (LSEBI). Methods Fifty suspicious patients with MACBF beside the main pulmonary artery and/or the left pulmonary artery undergoing echocardiography examination from November 2018 to April 2019 in Shengjing Hospital of China Medical University were chosen as the subjects. Image characteristics of the MACBF were observed, and mechanism and influence factors of the MACBF were explored with Doppler imaging principle. Results Of all the subjects with MACBF, 36 subjects occurred only on the left side of the main pulmonary artery, 14 subjects occurred on both the left side of the main pulmonary artery and the left pulmonary artery. The LSEBI was found between the real color blood flow (RCBF) and the MACBF, there was a mirror relationship between the RCBF and the MACBF. The LSEBI on the left of the main pulmonary artery and the left pulmonary artery were the interface of the left lung and pleural. The signal strength of MACBF enhanced as the distance between the blood flow and the LSEBI got closer or the gain of the color blood flow got bigger. Conclusions MACBF may caused by LSEBI beside vessel. The formation of MACBF and its signal strength are influenced by the distance between blood flow and LSEBI and the gain of the color blood flow.

Objective To construct the Z-score models for normal fetal brain fissures. Methods Four hundred and eighty-seven pregnant woman who underwent prenatal ultrasonography from January to August 2018 in the Second Xiangya Hospital of Central South University were collected randomly for analysis, and all the fetuses(18-38 weeks) were healthy. The calacarine fissure, pariet-ooccipital fissure, sylvian fissure of the fetuses were measured and they were chosed as the dependent variables, while the independent variable were the gestational age and biparietal diamete, as well as femur length. The regression analyses of the mean(M) and the standard deviation(SD) for each parameter were performed separately. Two observers randomly measured the brain fissures depth two hours apart to evaluate the interobserver repeatability. Results The brain fissure depth in normal fetuses during geatational age between 18 to 38 weeks can be evaluated by Z-score model.Positive correlations were found between the depth of calacarine fissure, pariet-ooccipital fissure, sylvian fissure and gestational age, biparietal diameter and femur length. Conclusions Z-score can intuitively reflect the development of brain fissure more accurate, and is valuable, and can be used as a powerful supplement to the traditional method.

Objective To investigate the value of contrast-enhanced ultrasound(CEUS) in differential diagnosis of complex renal cysts and clear renal cell carcinoma with cystic change(CRCCC). Methods The ultrasonographic datas of 82 lesions in 82 patients with complicated renal cysts or CRCCC confirmed by pathology were analyzed. The characteristics of conventional ultrasound and CEUS were observed and evaluated. The lesions were graded according to Bosniak classification criteria. Results Pathological examination showed that 36 cases were complicated renal cysts and 46 cases were CRCCC. Routine ultrasound showed there were 9 cases (25.0%) with cystic masses and 27 cases (75.0%) with solid and cystic masses in complex renal cysts, of which 14 cases (38.9%) could detect color flow signals. In CRCCC, 2 cases (4.3%) were with cystic masses and 44 cases (95.7%) were with solid and cystic masses, of which 33 cases (75.0%) could detect color flow signals. CEUS showed that only 18 cases (50.0%) of the complex renal cysts showed enhancement of cystic wall or septum, with equal or low enhancement at the peak, 9 cases (50.0%) accompanied by decrease of renal cortex, 35 cases (97.2%) had thin and regular cystic wall, no enhancement of cystic wall in all lesions, and 33 cases (91.7%) had septal thickness less than 1 mm. Forty-five cases (97.8%) of CRCCC showed enhancement of cystic wall or septum, 40 cases (88.9%) showed equal or high enhancement at peak, 30 cases (66.7%) were faster than the decrease of renal cortex, 37 cases (80.4%) showed uneven thickness of cystic wall, 24 cases (52.2%) showed enhancement of cystic wall nodules, and 28 cases (60.9%) showed uneven thickness of septum. After CEUS, 33 cases (91.7%) of complex renal cysts were classified as grade Ⅰ and Ⅱ, while 42 cases (91.3%) of CRCCC were classified as grade Ⅲ and Ⅳ. Conclusions The CEUS manifestations of complex renal cysts are different from those of CRCCC. The application of Bosniak criteria in CEUS is helpful for the differential diagnosis of complex renal cysts and CRCCC.

The characteristics of conventional ultrasound and CEUS were observed and evaluated. The lesions were graded according to Bosniak classification criteria. \u0000 \u0000 \u0000Results \u0000Pathological examination showed that 36 cases were complicated renal cysts and 46 cases were CRCCC. Routine ultrasound showed there were 9 cases (25.0%) with cystic masses and 27 cases (75.0%) with solid and cystic masses in complex renal cysts, of which 14 cases (38.9%) could detect color flow signals. In CRCCC, 2 cases (4.3%) were with cystic masses and 44 cases (95.7%) were with solid and cystic masses, of which 33 cases (75.0%) could detect color flow signals. CEUS showed that only 18 cases (50.0%) of the complex renal cysts showed enhancement of cystic wall or septum, with equal or low enhancement at the peak, 9 cases (50.0%) accompanied by decrease of renal cortex, 35 cases (97.2%) had thin and regular cystic wall, no enhancement of cystic wall in all lesions, and 33 cases (91.7%) had septal thickness less than 1 mm. Forty-five cases (97.8%) of CRCCC showed enhancement of cystic wall or septum, 40 cases (88.9%) showed equal or high enhancement at peak, 30 cases (66.7%) were faster than the decrease of renal cortex, 37 cases (80.4%) showed uneven thickness of cystic wall, 24 cases (52.2%) showed enhancement of cystic wall nodules, and 28 cases (60.9%) showed uneven thickness of septum. After CEUS, 33 cases (91.7%) of complex renal cysts were classified as grade Ⅰ and Ⅱ, while 42 cases (91.3%) of CRCCC were classified as grade Ⅲ and Ⅳ. \u0000 \u0000 \u0000Conclusions \u0000The CEUS manifestations of complex renal cysts are different from those of CRCCC.

Objective To evaluate the correlation between ultrasound features of papillary thyroid carcinoma (PTC) and lymph node metastasis by preoperative ultrasound elemental observation of thyroid nodules. Methods Three hundred and seventy-six patients who underwent primary thyroid surgery and confirmed by ultrasound and pathological data as single-focal PTC from Jannary to December 2017 in Sir Run Run Shaw Hospital of Zhejiang Univbersity College of Medicine were retrospectively analyzed. According to the presence or absence of lymph node metastasis, they were divided into central and lateral lymph node metastasis group and non-metastasis group. Independent risk factors for central lymph node metastasis (CLNM) and lateral lymph node metastasis (LLNM) were analyzed by χ2 test and multivariate Logistic regression. Results Multivariate analysis showed that the posterior margin of the cancer was 0.38 cm3 (P=0.000), was more prone to CLNM. And multivariate analysis showed that the anterior margin of the cancer was 2 cm (P=0.001) group was more prone to LLNM. Compared with the tumor volume ≤0.38 cm3, the tumor volume >0.38 cm3 (P=0.000) was more prone to LLNM. Conclusions The larger volume of single focal PTC carcinoma and the closer to the posterior thyroid capsule are independent risk factors for CLNM. The larger volume and diameter of single focal PTC, and the closer to the anterior and medial wall capsule are independent risk factors for LLNM.

Objective To explore the value of superb micro-vascular imaging(SMI) combined with conventional ultrasound in differential diagnosis of polypoid lesions of gallbladder. Methods The ultrasonographic and pathological datas of 67 patients with polypoid lesions of gallbladder (of ≥1 cm) in diameter were analyzed retrospectively. According to the pathological results, the patients were divided into tumorous polyp group and non-tumorous polyp group.Conventional ultrasound, SMI and contrast-enhanced ultrasound (CEUS) were performed in all patients before operation, and the basal width, continuity of cystic wall and internal blood flow morphology of polyps were evaluated. The ROC curve was used to calculate the area under the curve and the optimum boundary value of tumorous polyps, the sensitivity and specificity of SMI combined with conventional ultrasound in the diagnosis of neoplastic polyps were calculated according to the optimal threshold. Kappa consistency test was used to analyze the consistency between microblood flow ability and CEUS shown by SMI technique. Results Of the 67 patients, 22 cases were neoplastic polyps, and 45 cases were non-neoplastic polyps.The polyps were scored quantitatively by SMI combined with conventional ultrasound (0-9 points) and the ROC curve was plotted with, area under curve 0.893(95% CI 0.792-0.994). The sensitivity, specificity and accuracy of diagnosing neoplastic polyps with score (≥4.5) were 77.3%, 93.3% and 88.1%, respectively. Compared with the score of CEUS for microblood flow display (0-4 points), the Kappa values of CDFI, SMI was 0.186, 0.688. SMI and CEUS have good consistency. Conclusions SMI combined with conventional ultrasound is helpful in differential diagnosis of polypoid lesions of gallbladder, with a high diagnostic value. SMI and CEUS have good consistency in the display of micro-blood flow. It can provide a new diagnostic basis for differential diagnosis of polypoid lesions of gallbladder.
