DOI: 10.12117/jccmi.2020.03.002
Objective: To summarize the clinical manifestations, image characteristics and proper imaging modalities of diagnosis of Sturge-Weber syndrome(SWS), and to improve the understanding and reduce misdiagnosis of SWS. Methods: Clinical features, CT, MRI and DSA images of 44 children with SWS were retrospectively reviewed. Results: Forty-four cases had ipsilateral leptomeningeal angiomatosis(12 cases were bilateral) diagnosed with CT, MRI and DSA, children presenting with seizures(n=35), ipsilateral port-wine nevus affecting the area innervated by the first and second sensory branch of the trigeminal nerve(n=33), headache(n=4), hemiparesis(n=4). CT, MRI and DSA examinations were performed in 30, 38 and 14 children respectively. One child had MR spectroscopy(MRS) and 5 children had further study of susceptibility weighted imaging(SWI). Forty-four SWS children were diagnosed with ipsilateral leptomeningeal angiomatosis after different imaging modalities and clinical manifestations. CT images showed gyriform calcifications in different regions(n=25), especially in the occipitoparietal, frontoparietal, temporoparietal or fronto-temporo-occipital regions. Ipsilateral leptomeningeal angiomatosis and abnormal veins(n=34), choroidal angioma(n=21), cerebral atrophy(n=34), and glaucoma(n=10) were shown in postcontrast MRI in 34 children. Conclusion: SWS is a rare sporadic and congenital neurocutaneous syndrome. CT is sensitive in gyriform calcifications. MRI has advantages of non-radiation and multi-planar scanning. Contrast enhanced MRI and SWI sequence should be suggested in any child presented with epilepsy and intracranial unilateral calcification, which can also be used as the preferred imaging method for the early diagnosis and follow-up study of SWS.

DOI: 10.12117/jccmi.2020.03.003
Objective: To explore the diagnostic value of conventional MRI sequence and ADC value of DWI in neonatal hypoglycemic brain injury. Methods: A total of 48 cases of neonatal hypoglycemic brain injury were included with complete clinical, imaging and laboratory data from June 2016 to January 2019 in our hospital. The MRI findings were analyzed, and we divided the 48 cases into 3 groups according to the blood glucose level(group a: ≤1.0 mmol/L, group b: ＞1.0~1.7 mmol/L, group c: ＞1.7~2.2 mmol/L). We use SPSS 23.0 software to analyze the difference of ADC values among different groups and the correlation with blood glucose. Results: ①There were 17 patients in group a, 17 patients in group b, and 14 patients in group c. Among them, lesions of 28(58%) were more obviously showed in DWI than in conventional sequences(T1WI, T2WI). ②The ADC values were different among different groups(a, b, c). As the severity of hypoglycemia increased, the ADC value decreased, and the difference was statistically significant(P<0.01). ③The ADC value was strongly correlated with the severity of hypoglycemia, and the correlation coefficient r was 0.761. Conclusion: DWI is more sensitive in showing the location, extent and severity to hypoglycemic brain injury than MRI routine sequences. ADC value plays an important role in evaluating the severity of neonatal hypoglycemic brain injury.

DOI: 10.12117/jccmi.2020.03.004
Objective: To study and analyze the clinical diagnostic value of ultrasound in the differential diagnosis of ocular masses. Methods: From March 2015 to February 2019, 33 patients with ocular mass were selected as the research objects. The sensitivity, specificity and accuracy of ultrasonography in the diagnosis of benign and malignant ocular masses were analyzed. At the same time, the detection rates of various benign and malignant ocular masses by ultrasound and pathology were compared. Results: The sensitivity, specificity and accuracy of ultrasound in the differential diagnosis of benign and malignant ocular masses in 33 cases were 96.15%, 85.71% and 93.94%, respectively. The results of ultrasonographic diagnosis of cavernous hemangioma, pleomorphic adenoma, hemangioma, inflammatory pseudotumor and venous hemangioma were consistent with the results of surgical biopsy, and the differences were not statistically significant(all P>0.05). The results of ultrasonographic diagnosis of choroidal melanoma, basal cell carcinoma, dacryocyst fascia fibrosarcoma, primary lymphocytic lymphoma, eyelid squamous cell carcinoma and malignant melanoma of eyelid were the same as those of surgical biopsy, but the detection rate of adenoid cystic carcinoma was 0.00%, with no statistically significant difference(all P>0.05). Conclusion: Ultrasonography is of high clinical value in the differential diagnosis of ocular masses, and has a high detection rate for malignant and benign ocular masses, which is worthy of clinical application.

DOI: 10.12117/jccmi.2020.03.005
Objective: To explore the application value of quantitative assessment of age-related reduction of carotid artery elasticity by ultrafast pulse wave velocity and the effect of mean arterial pressure on it. Methods: A total of 435 patients, 138 healthy adults and 297 patients with risk factors for atherosclerosis were enrolled, and divided into 5 groups according to age intervals(25~＜35, 35~＜45, 45~＜55, 55~＜65, ≥65 years old). Detailed clinical data were collected from all the enrolled subjects, and pulse wave velocity of beginning systole(PWV-BS) and pulse wave velocity of ending systole(PWV-ES) of bilateral carotid artery were measured by ufPWV technology. The correlations between PWV-BS, PWV-ES, MAP and age were analyzed. Then the differences of PWV-BS and PWV-ES among different age intervals were compared, and the possible influence of blood pressure on ufPWV detection was further analyzed according to the stratification of mean arterial pressure(MAP). Results: There were great significant correlations between age and PWV-BS(r=0.25, P<0.001), PWV-ES(r=0.615, P<0.001), MAP(r=0.25, P<0.001). Both PWV-BS and PWV-ES were increased with age(P<0.001). When divided by MAP categories, the PWV-ES of the high MAP subgroup(MAP≥100 mmHg) and the low MAP subgroup(MAP<100 mmHg) both increased with age. The PWV-ES of the high MAP subgroup were significantly higher than those of the low MAP subgroup at the age intervals of 25~＜35, 35~＜45, 45~＜55, 55~＜65 years old(all P<0.05), but there was no significant difference at the age interval of ≥65(P=0.126). Conclusions: Different mean arterial blood pressure has significant influence on the quantitative evaluation of age-related carotid arterial elastic degeneration by ufPWV, so the effect of different blood pressure and age on the measured value of carotid artery elasticity should be noted in the clinical application of this technology.

DOI: 10.12117/jccmi.2020.03.006
Objective: To analyze the characteristics of 99mTc-MIBI SPECT/CT dual-phase imaging in patients with hyperparathyropathy, combined with the serum PTH levels, to explore the correlation with MIBI imaging results. Methods: Retrospective analysis of MIBI imaging data of 143 patients with elevated serum PTH which were suspected of hyperparathyropathy from June 2016 to April 2019. Results: ①The median PTH levels of primary(PHPT) and secondary(SHPT) hyperparathyropathy were 110(65.7~998.5) pg/mL and 1 725(368.3~3 533.0) pg/mL, respectively. There was significant difference between the two groups(Z=-8.79, P=0.000), SHPT group was significantly higher than that in PHPT group.②The positive rates of MIBI planar imaging and tomographic imaging were 57.3% and 68.5%, respectively. ③According to the MIBI imaging results, the PHPT patients were divided into positive group and negative group. The serum PTH levels were different between the two groups(Z=-5.32, P=0.00). The level of PTH was significantly higher in positive group. ④The age, gender and PTH value were taken as independent variables, and the results of tomographic imaging were used as dependent for logistic regression analysis. The influencing factor in PHPT group was PTH value(OR: 1.014, 95%CI: 1.005~1.024, r=0.52, P<0.00). Correlation coefficient r=0.52, P=0.00. No related factors was found in SHPT group. ⑤The ROC curves of planar imaging and tomographic imaging in PHPT group were drawn. The areas under the curve were 0.75 and 0.81, the cutoff values of PTH were 115.6 and 112.9, and the positive predictive values were 75.0% and 86.5%, respectively. Conclusion: The level of serum PTH in patients with secondary hyperthyroidism was higher than that in patients with primary hyperthyroidism. The level of serum PTH was correlated with the results of MIBI imaging in patients with primary hyperthyroidism. The higher level of serum PTH means the higher positive rate of MIBI imaging. The cutoff values were 115.6 pg/mL and 112.9 pg/mL, and the corresponding positive predictive values were 75.0% and 86.5%, respectively.

BAI Yang, LIU Juan-juan, NING Hong-xia, MA Chun-yan, YANG Jun
DOI: 10.12117/jccmi.2020.03.007
Objective: Real-time three-dimensional echocardiography(RT-3DE) was used to assess reverse remodeling of the right ventricle(RV) following short-term therapy in patients with connective tissue disease associated pulmonary arterial hypertension(CTD-PAH). Methods: Consecutive CTD patients admitted to the Department of Rheumatology and Immunology of our hospital from July 2015 to December 2018 were selected. According to the 2015 ESC/ERS guidelines for pulmonary hypertension(PH), those patients with “high” PH possibility were enrolled. Echocardiographic parameters derived from conventional echocardiography and RT-3DE including pulmonary arterial systolic pressure(PASP), right ventricular end-diastolic volume index(RVEDVi), end-systolic volume index(RVESVi) and ejection fraction(RVEF) were measured. Clinical data were collected including the types of CTD diseases, drug treatment, WHO functional classification, BNP, etc. The patients were followed up for 3 to 6 months after the initial enrolled. Clinical improvement was defined according to the follow-up clinical situation, and the RV reverse remodeling in patients with clinical improvement was analyzed. Results: After an average follow-up time of 4.2±0.9 months, 56.1% of the 57 patients achieved clinical improvement, and the BNP and PASP in the improved group were lower than those in the non-improved group at baseline(P<0.01). During the follow-up of the improved group, WHO-FC, BNP and PASP were significantly decreased, RV volume was significantly decreased, and RVEF was significantly increased(P<0.001). The change of PASP was not significantly correlated with the change of BNP level, while the change of RV volume and RVEF were significantly correlated with the change of BNP level, among which RVESVi had the best correlation with BNP(r=0.651, P<0.001). Conclusions: RV reverse remodeling in CTD-PAH patients is significantly correlated with BNP reduction and RVESVi derived from RT-3DE can be used as a good indicator to evaluate RV reverse remodeling.

DOI: 10.12117/jccmi.2020.03.008
Objective: To explore a non-invasive method for the determination of coronary flow reserve(CFR) by stress myocardial contrast echocardiography(MCE) and its application in evaluating coronary microcirculation dysfunction(CMD). Methods: A total of 161 patients with non-obstructive coronary artery disease hospitalized due to chest pain were enrolled. All patients underwent adenosine triphosphate(ATP) stress MCE, and QLab was used to quantitatively analyze the myocardial plateau signal intensity(A) and signal intensity exchange rate(β) at rest and post-stress. Myocardial blood flow(MBF) is expressed as A×β, and CFR equals stress MBF divided by rest MBF. CMD is defined as CFR<2.0. Multivariate Logistic regression analysis was used to screen the influencing factors of CMD. Results: The incidence of CMD in patients with non-obstructive chest pain was 51.6%. Compared with the normal group, the incidence of diabetes, hyperlipidemia and the proportion of E/e’>15 in CMD was significantly increased. Multivariate Logistic regression analysis showed that E/e’>15 was an independent risk factor for CMD. Conclusion: MCE is an effective noninvasive method for the determination of CFR. The incidence of CMD in patients with non-obstructive chest pain was 51.6%. It was also associated with increased left ventricular end-diastolic pressure.

DOI: 10.12117/jccmi.2020.03.009
Objective: Through comparing ultrasonic imaging characteristics and the results of surgical pathological diagnosis and clinical follow-up of cardiac tumor, to summarize the ultrasonic imaging characterization and improve the identification of it. Method: Sixty-three cases of suspected cardiac tumor were found by color Doppler echocardiography examination in the First Affiliated Hospital of Tsinghua University from January 2003 to October 2019. The clinical features, echocardiograms characteristics, the results of surgical pathological diagnosis and clinical follow-up of these patients were compared and analyzed retrospectively. Results: Among 63 patients, 27(43%) were males, and 36(57%) were females. The age range was from 4 months to 83 years old. The average age was 35.5 years. All cardiac tumors obtain pathologic confirmation. There were 49 cases of benign tumors, including 28 patients with myxoma and 21 patients with other types. Eleven cases of malignant tumors and 2 cases of metastatic tumors, 1 case of thrombus. Benign myxoma was diagnosed in 28 cases preoperatively by ultrasound examination, which were consistent with surgical pathological results with accuracy of 100％． However there were 23 cases whose pathologic types could not be determined by ultrasound examination． Twenty cases were speculated as benign tumors and 3 cases were speculated as malignant tumor, but 21 cases were diagnosed as benign tumors, 1 case was diagnosed as malignant tumor and 1 case was diagnosed as thrombus according postoperative pathological results． Twelve cases diagnosed as malignant by UCG, being consistent with postoperative pathological results． Conclusion: The accuracy of ultrasonography in predicting myxoma is high． Cardiac tumors that invaded the heart system and were associated with pericardial effusion were more likely to be malignant. Ultrasound was the main examination in the diagnosis of cardiac tumors, combined with the history, by scanning the special features of the sonogram, misdiagnosis and missed diagnosis can be avoided or reduced.

DOI: 10.12117/jccmi.2020.03.011
Objective: To evaluate the changes of left ventricular systolic function in breast cancer patients after sequential application of anthracyclines and trastuzumab chemotherapy by two-dimensional speckle tracking imaging(2D-STI) layer-specific strain analysis. Methods: Thirty patients diagnosed with breast cancer and sequential application of chemotherapy and anthracycline-trastuzumab were selected as the case group(group A), and 27 normal subjects were selected as the control group(group B). The 2D images of patients in group A were collected and stored before chemotherapy(T0 phase), after 4 cycles of anthracycline(T1 phase) and after sequential 17 cycles of trastuzumab(T2 phase). The conventional echocardiographic parameters and the global longitudinal strain(GLS) in each myocardial layer were measured and compared. Results: ①There were no significant differences in the conventional echocardiographic parameters and GLS between the group A in the T0 phase and group B(P>0.05). ②There was no significant difference in the LVEF between T1, T2 and T0 phases in the group A(P>0.05). In the T1 phase, the endocardial GLS was significantly lower than that in the T0 phase. The endocardial and mid-myocardial GLS in the T2 phase were significantly lower than those in the T0 phase, and the differences were statistically significant(P<0.01). ③There was no significant difference in LVEF between the T2 and T1 phases in group A. The endocardial and midmyocardial GLS in the T2 phase were significantly lower than those in the T1 phase. The difference was statistically significant(P<0.05). Conclusion: The 2D-STI layer-specific strain analysis could accurately evaluate the left ventricular systolic function by analyzing the GLS in each myocardial layer, so it might be used to reflect the subclinical cardiotoxicity of patients after sequential application of anthracyclines and trastuzumab.

LIU Xiang-jun, WANG Lian-yi, LI Hong-yin, CUI Jian
DOI: 10.12117/jccmi.2020.03.012
Objective: To elucidate the feasibility of tricuspid annular plane systolic excursion(TAPSE) and Tei index of right ventricle(RV) to evaluate right heart function of Ebstein anomaly(EA) patients before and after operation. Methods: Forty EA patients and twenty healthy controls underwent echocardiography(UCG) for evaluation of right heart function. EA patients underwent UCG before operation,one week and three months after operation, respectively. TAPSE was measured, Tei index of RV was calculatedin four-chamber view by tissue Doppler. Results: The study result showed that the echocardiographic parameters of RV systolic function including TAPSE, RVFAC, were decreased before the operation. However, the RV Tei index which reflected both the systolic and diastolic function of RV was increased before the operation. TAPSE improved significantly both on 1 week and 3 months after the operation(P<0.01). TAPSE was correlated with RVFAC. RVFAC is not suitable for postoperative comparison with preoperative use in the assessment of RV function before and after tricuspid regurgitation correction surgery. It is only suitable for comparison between different stages after operation. Conclusion: TAPSE and RVTei index assess the preoperative and postoperative patient’s RV function. The role of the tricuspid valve repair on improving the right heart function was also confirmed, and more experience could be accumulated on evaluation of right heart function.

DOI: 10.12117/jccmi.2020.03.013
Objective: To evaluate the longitudinal contractile function, synchrony and location of papillary muscle in patients with hypertrophic cardiomyopathy(HCM) with two-dimensional speckle tracking echocardiography(2D-STE). Methods: Thirty-four patients diagnosed with HCM by transthoracic echocardiography and thirty-four healthy people at the same period were collected. 2D-STE was used to evaluate the longitudinal strain of papillary muscle. The time difference between the time from the starting point of QRS to the peak strain of the two papillary muscles and the circumference angle of papillary muscle, the differences of various parameters between the two groups were compared. Results: The circumferential angle of the two papillary muscles and the area of the anterior lateral papillary muscle were significantly higher in the HCM group than in the control group(P<0.05). The segments of the papillary muscles and the overall longitudinal strain of HCM patients were lower than those of the normal control group(P<0.05). The difference in strain peak time between the two papillary muscles in the HCM group was significantly greater than that in the control group, and the difference was statistically significant(P<0.05). Conclusion: In HCM patients, the papillary muscles move forward, the longitudinal contraction function of the papillary muscles is reduced, and the contraction of the two papillary muscles is not synchronized. Papillary muscle function can be fully evaluated using 2D-STE.

DOI: 10.12117/jccmi.2020.03.014
Objective: To explore application value of real-time three-dimensional transesophageal echocardiography(3D-TEE) in the diagnosis and occlusion of mitral perivalvular leakage. Methods: Ten patients who diagnosed with mitral perivalvular leakage were selected in our hospital to underwent transthoracic echocardiography(TTE) and 3D-TEE. All patients with perivalvular leakage underwent closure guided by DSA or 3D-TEE. The width, length, and position of perivalvular leakage were measured by TTE and TEE. Results: There was no significant difference in the width of perivalvular leakage measured by TEE or TEE(P＞0.05). The length of perivalvular leakage measured by TEE was obviously longer than by TTE(P＜0.05). In the process of occlusion, 8 patients were guided by DSA and TTE, and 2 patients were guided by TEE only. The 3D-TEE is of great value in the selection and release of occlusion umbrella and the evaluation of residual shunt. Conclusions: TTE was used to preliminary screen of mitral perivalvular leakage. 3D TEE was used to accurately evaluate the mitral perivalvular leakage and release of occlusion umbrella.
