DOI: 10.12117/jccmi.2019.01.001
Ultrasound is the preferred imaging method for screening fetal structural abnormalities and assessing fetal growth and development, and plays an important role in reducing the rate of birth defects. In recent years, fetal ultrasound medicine has developed very rapidly. The prenatal ultrasound guidelines have been continuously updated and refined. The Chinese fetal ultrasound examination specifications are also in line with international standards. The application of new technologies such as 3D/4D helps to diagnose the diseases. The development of artificial intelligence helps to simplify fetal ultrasound scanning and promote the training of primary doctors. With the precision of prenatal diagnosis, multidisciplinary collaboration will become increasingly important.

DOI: 10.12117/jccmi.2019.01.002
Objective: The purpose of this study was to evaluate the right ventricular(RV) dyssynchrony in pulmonary hypertension(PH) patients using equilibrium radionuclide angiography(ERNA). Methods: Thirty-five PH patients and twenty healthy controls were included. ERNA was performed to calculate both RV ejection fraction(RVEF) and dyssynchrony parameters including RV phase shift(RVmPA) and RV phase standard deviation(RVPSD). The 6-minute walking distance(6-MWD) and N-terminal pronatriuretic peptide(NT-proBNP) were also detected to evaluate RV function of PH patients. Results: The mean RVEF, RVmPA and RVPSD of the PH group were 36.57±7.43%, (403.91±81.78)ms, and (54.46±15.05)ms, respectively. Compared with the control group, RVEF was significantly decreased(P<0.001), while RVmPA and RVPSD were significantly increased(P<0.001). RVmPA and RVPSD were significantly correlated with RVEF, 6-MWD and NT-proBNP(RVmPA: r=0.725, 0.645, 0.633, P<0.001; RVPSD: r=0.804, 0.733, 0.725, P<0.001). Conclusion: ERNA is feasible to evaluate RV mechanical dyssynchrony in PH patients. RV dyssynchrony parameters measured by phase analysis of ERNA were significantly correlated with RV function.

PENG Yu-dong1, PENG Hong-tao2
DOI: 10.12117/jccmi.2019.01.003
Objective: To explore right ventricular circumferential strain in pulmonary arterial hypertension(PAH) using speckle tracking echocardiography. Methods: The subjects are PAH patients and healthy controls. Right ventricular fractional area change(RVFAC) was calculated in the apical four-chamber view. Right ventricular short-axis two-dimensional images were aquired. Right ventricular circumferential strain(ε) was collected in the QLAB9.0 workstation. The difference of ε between the two groups was analyzed. Results: Compared with the control group, PAH patients showed decreased circumferential strain in anterior wall, free wall, inferior wall of right ventricle in the basal level, free wall of right ventricle in the middle level, and anterior wall of right ventricle in the apical level. Also, the global circumferential strain of right ventricle was reduced(P<0.05). Right ventricular circumferential strain showed a modest correlation with RVFAC. Conclusion: Right ventricular circumferential strain is decreased in PAH patients, demonstrating that right ventricular short axis contractility of PAH patients is reduced. There is modest correlation between right ventricular circumferential strain and RVFAC.

ZHANG Wen, ZHU Qi, CHEN Jiao, GUO Nan, LIU Dan, WU Ting, DAI Xiao-hui, LUO Hong
DOI: 10.12117/jccmi.2019.01.004
Objective: To study the type and incidence of fetal arrhythmia by prenatal ultrasound and to explore the value of Cardiovascular profile scores(CVPS) in fetal arrhythmias. Method: 295 cases which were diagnosed with fetal arrhythmia  and got further examination in Department of Ultrasound of West China Second Hospital of Sichuan University from January 2008 to January 2018 were recruited. Stratified according to CVPS scores, we summarized the type of fetal arrhythmia, the type of intra-cardiac and extra-cardiac malformation and analyzed the prognosis of these fetuses. Results: The average age of 295 pregnant women was 27.4±5.6 years, and the average gestational age was 30.6±4.9 weeks. Among them, there were 0 fetuses with a CVPS score less than 4, and there were 1, 9, 15, 21, 34, 48 and 167 fetuses with a CVPS score between 4 and 10, respectively. Among them, there were 190 cases(64.4%) of atrial arrhythmia, 28 cases(9.5%) of ventricular arrhythmia, 28 cases(9.5%) of supraventricular tachycardia, 39 cases(13.2%) with atrioventricular conduction block and 15 cases(5.1%) with sinus bradycardia. 51(17.3%) fetuses had intra-cardiac malformations, 14(4.7%) had extra-cardiac malformations. 54 cases(18.3%) were in the adverse pregnancy outcome group and 210 cases(71.2%) were in the live birth group, but 31 cases(10.5%) were lost to follow up. ROC curve analysis showed that the area under the curve(AUC) was 0.754, and the cut-off value of 8.5(P<0.05) in the live birth group and the adverse pregnancy outcome group, with a sensitivity of 82.4% and a specificity of 59.3%. Conclusion: In fetal arrhythmias, atrial arrhythmia accounts for the majority, which is similar to ventricular arrhythmia, CVPS scores of both are higher, and the prognosis of both can be better. For the fetus who has a significantly lower CVPS score, the incidence of complicated intra-cardiac and extra-cardiac malformations and adverse pregnancy outcome is relatively higher. Therefore, the fetal CVPS has important guiding significance for the prediction of fetal arrhythmia pregnancy outcome.

DOI: 10.12117/jccmi.2019.01.005
Objective: To evalutate the right ventricular function of the fetuses with isolated tricuspid regurgitation using tissue Doppler Tei index together with ductus venous blood flow parameters. Methods: 253 fetuses from 20 to 41+6 weeks were divided into 3 groups, 165 fetuses without tricuspid regurgitation as the control group, 68 fetuses with mild tricuspid regurgitation as the mild regurgitation group, 20 fetuses with moderate tricuspid regurgitation as the moderate regurgitation group. Tissue Doppler imaging(TDI) technique was used to measure the isovolumic contraction time(ICT), isovolumic relaxation time(IRT) and ejection time(ET) of right ventricle in all fetuses. The S/A, resistence index(RI) and pulsation index(PI) of fetal ductus venous blood flow were also measured. Results: There were no significant differences in right ventricular Tei index, ICT＋IRT, ET, and ductus venous blood flow parameters between the mild regurgitation group and the control group(P＞0.05). The right ventricular Tei index, ICT＋IRT, and ductus venous blood flow parameters of the moderate regurgitation group were higher than those of the control group and the mild regurgitation group(P＜0.05). The ET of the moderate regurgitation group was lower than that of the control group and the mild regurgitation group(P＜0.05). Conclusion: The right ventricular Tei index and ductus venous blood flow parameters can be used to evaluate the right ventricular function of the fetuses with tricuspid regurgitation, which can provide an important basis for clinical intervention.

DOI: 10.12117/jccmi.2019.01.006
Objective: To explore the application value of spatio-temporal image correlation M-mode(STIC-M) together with tissue Doppler imaging(TDI) in evaluation of right ventricular function of the fetus with tricuspid regurgitation. Methods: 243 fetuses from 20 to 41+6 weeks were divided into 3 groups, 160 fetuses without tricuspid regurgitation as the control group, 63 fetuses with mild tricuspid regurgitation as the mild regurgitation group, 20 fetuses with moderate tricuspid regurgitation as the moderate regurgitation group. STIC-M was used to measure the tricuspid annular displacement(TAD). TDI was used to measure early and late diastolic tricuspid annular velocity(E' and A'), as well as E'/A'. Statistical analysis was performed to compare these parameters. Results: There were no significant differences in TAD, E', A' and E'/A' between the mild regurgitation group and the control group(P＞0.05). The TAD, E', A', and E'/A' of the moderate regurgitation group were significantly lower than those of the control group and the mild regurgitation group(P＜0.05). Conclusion: STIC-M combined with TDI can accurately evaluate right ventricular systolic and diastolic function of the fetuses with tricuspid regurgitation, which can provide important information in guiding the active clinical treatment and choosing the appropriate delivery opportunity.

WANG Kun, ZHANG Xiao-hua, DONG Feng-qun
DOI: 10.12117/jccmi.2019.01.007
Objective: To explore the application value of coronal plane in ultrasonic diagnosis of fetal total anomalous pulmonary venous drainage(TAPVD). Methods: A series of coronal sections of the chest and abdomen were obtained with the beam coming from the left or right side of the fetuses in 19 cases of simple total anomalous pulmonary venous drainage (TAPVD) diagnosed by echocardiography to demonstrate location and path of pulmonary venous drainage. The types of the total anomalous pulmonary venous drainage were classified and compared with postpartum echocardiography results, surgical results or autopsy results. Results: All 19 cases of simple fetal TAPVD were confirmed postpartum, including 8 cases of supracardiac type. There were 8 cases with complete drainage pathway displayed and accurately classificated using coronal plane imaging. There were 6 cases of intracardiac type, and there were 2 cases with complete drainage location and pathway displayed and accurately classificated by coronal plane. There were 2 cases of infracardiac type, and there were 2 cases with complete drainage pathway displayed and accurately classificated by coronal plane. There were 3 cases of mixed type, of which 2 cases’ drainage pathway was supercardiac type+subcardiac type, and 1 was supercardiac type+intracardiac type, and there were 2 cases with complete drainage pathway displayed and accurately classificated by coronal plane. Conclusion: For the fetal supracardiac type and infracardiac type TAPVD, coronal section has obvious advantages, which can judge the pulmonary venous drainage path quickly and accurately, make accurate classification and provide accurate guidance for clinical prognosis evaluation. For the display of pulmonary venous drainage pathway in intracardiac type TAPVD, the advantage of coronal section is not obvious. For the mixed type TAPVD, coronal plane shows the drainage path with a certain advantage because of its complex and varied drainage path. Coronal section has guiding value for the diagnosis of obstruction and the location of obstruction in the pulmonary venous drainage pathway.

DOI: 10.12117/jccmi.2019.01.008
Objective: To study and analyze the clinical value of prenatal ultrasound diagnosis in fetal cardiovascular malformations. Methods: 1 000 cases of pregnant women from January 2014 to January 2017 in the First Central Hospital of Baoding were selected as the research objects, the prenatal ultrasound examination was implemented, the test results were analyzed, and the results were compared with postnatal autopsy or postpartum ultrasound examination results. Results: 57 cases of fetal cardiovascular malformations were found through prenatal fetal echocardiographic examination in 1 000 cases of pregnant women, and the malformation rate was 5.7%(57/1 000). There were 36 cases diagnosed by cardiovascular ultrasound after delivery, 11 cases confirmed by autopsy after induction of labor, and 10 cases lost to follow-up, the accuracy rate of prenatal ultrasonography was 82.46%(47/57). 2 cases of ductus arteriosus tortuosity and stenosis were re-examined after 1 month of delivery, and the results were normal; 2 cases of ventricular septal defect wereclosed after 4 months of delivery. 943 cases of maternal prenatal fetal echocardiographic examination showed no abnormalities, including 4 cases diagnosed with ventricular septal defect or atrial septal defect by echocardiography after birth; advanced age and ectopic pregnancy are high risk factors for cardiovascular malformations of the fetus. Prenatal ultrasound examination in early pregnancy and reexamination in late pregnancy are appropriate timing for ultrasound examination. Conclusion: Prenatal ultrasonography can effectively improve the quality of maternal delivery and improve the quality of life of newborns, which has important clinical value.

ZHANG Li-na, WU Qing-qing, HAN Ji-jing, SUN Li-juan, LI Zhen, ZHANG Na
DOI: 10.12117/jccmi.2019.01.010
Objective: To discuss the clinical value of Doppler ultrasound monitoring myocardial performance index in growth restriction fetuses. Method: A total of 173 cases including 75 early-onset fetal growth restriction(FGR) and 98 late-onset fetal growth restriction(FGR)(divided by 32 weeks of gestation) were recruited from January 2016 to January 2018. They underwent ultrasound examinations in our hospital and were followed up to the pregnancy outcome. The normal controls included 100 cases with <32 weeks and ≥32 weeks respectively. Fetal growth, structural abnormalities, umbilical artery(UA), ductus venosus(DV), middle cerebral artery(MCA) and myocardial performance index(MPI) were monitored and recorded routinely by Doppler ultrasound. The pregnancy outcomes of all cases were followed up. The study groups were divided into adverse and good pregnancy outcome groups. Result: ①The 95th percentile of normal fetuses before/after 32 weeks were 0.50 and 0.52 respectively. ②Compared with normal controls, Early-onset FGR fetuses had increased UA pulsatility index(PI), DV-PI and MPI while decreased parameters including DV-a, MCA- PI and Cerebro-placental Doppler Ratio(CPR). Moreover, increased MPI and decreased MCAS and MCA-RI were found in late-onset FGR cases. ③Compared with good pregnancy outcome group, adverse outcomes in early-onset FGR had increased UA-PI, MCAS, and MPI while decreased MCAD, MCA-RI, and CPR. Moreover, only increased MPI were found in late-onset FGR cases. Conclusion: Doppler ultrasound could diagnose early-onset FGR by monitoring blood flow spectrum changes of UA, MCA, DV and detect late-onset FGR only by the reduction of MCAS and MCA-RI. However, MPI has a high clinical value in the diagnosis and prediction of the prognosis of FGR with different types.

Objective: By analyzing prenatal imaging characteristics, regular intrauterine monitoring, and following up of fetuses with congenital choledochal cysts, to explore the diagnostic value, differential diagnosis and clinical significance of prenatal ultrasound, thus providing the basis for prenatal consultation and neonatal treatment. Methods: 45 cases of fetuses with choledochal cysts were recruited in this study. Their prenatal ultrasonography were analyzed and compared with the postpartum follow-up results, pathological results, thus the prognosis and outcome were summarized. Results: 2 of the 45 cases were lost to followed up. 43 cases were recruited in this study. 35 of 43 cases were diagnosed with congenital choledochal cysts by neonatal abdominal ultrasound examination, with 34 cases confirmed by surgical pathology of congenital choledochal cysts and 1 case dying of kernicterus due to delay of surgical intervention. The prenatal ultrasound diagnosis coincidence rate was 81.4%(35/43). Seven cases were misdiagnosed, with a misdiagnosis rate of 16.3%(7/43), including 4 cases of hepatic cysts, 2 cases of congenital biliary atresia and 1 case of ovarian cyst, all of which were treated with surgery. One case(1/3, 2.3%) had induced labor. Conclusions: Congenital choledochal cysts of fetuses can be detected by prenatal ultrasonography and are curable. Patients having surgical treatment timely and early after birth will have a good prognosis. Delayed surgery can cause irreversible damage to the liver.

Objective: To evaluate the diagnostic value of three-dimensional volume ultrasound in fetal hydronephrosis related diseases. Method: 85 pregnant women with fetal hydronephrosis were enrolled in this study. Three-dimensional volume ultrasound was used to measure the volume of kidney and calculate the ratio of renal parenchyma(the total volume of kidney -the hydronephrosis volume)/the total volume of kidney. Meanwhile, the fetal hydronephrosis was graded according to the Society for Fetal Urology(SFU) grading system. The prognosis of children was followed up. And the relationship between renal parenchymal ratio, SFU classification and prognosis was analyzed. Result: This study was included 170 kidneys in 85 fetuses. There were 122 cases diagnosed with renal pyelectasis, 37 cases diagnosed with bilateral renal pelvis dilatation, and 48 cases diagnosed with unilateral hydronephrosis(15 cases of right, 33 cases of left). According to SFU grading system, there were 29 kidneys in grade 0, 21 kidneys in grade 1, 58 kidneys in grade 2, 35 kidneys in grade 3 and 27 kidneys in grade 4, respectively. Three patients chose to terminate pregnancy. According to the follow-up outcomes, all patients were divided into three groups: 14 cases for postnatal surgery, 34 cases for postnatal periodic review(possibly later surgery), 34 cases for postnatal remission(the renal pelvis width was less than 1.0 cm). There was a significant difference in renal parenchymal ratio among different groups(P=0.001). Conclusion: Three-dimensional volume ultrasound combined with SFU classification could provide some helpful information of fetal hydronephrosis related diseases in prenatal diagnosis and counseling.

DOI: 10.12117/jccmi.2019.01.017
Objective: To evaluate the effect of low-dose coronary CT combined with Iterative Model Reconstruction on the image quality of coronary artery stent. Methods: Forty-six patients with PCI were recruited to undergo coronary CT angiography, with a total of 71 stents. CT scan parameters: Prospective ECG-gated scan, tube voltage 100 kV, tube current using automatic tube current debugging technology. The original data of the patient CT scan were reconstructed by filtered back projection(FBP), advanced mixed iteration(iDOSE4) and IMR. Three groups of reconstructed images were subjectively and objectively evaluated. Results: All patients were successfully completed. The noise(26.9±3.6) and the signal-to-noise ratio(16.5±2.9) of the IMR group were significantly better than those in the iDOSE4 group(54.6±9.2, 8.2±1.8) and FBP group(78.9±11.4, 5.6±1.1)(P<0.01). In the stent cavity display, the signal-to-noise ratio and contrast noise ratio in the IMR group were the highest, and those in the FBP group were the lowest. There was statistical difference between the two groups(P<0.01). IMR group had the highest subjective score. There was no significant difference between the IMR group and the iDOSE4 group in terms of diagnostic feasibility(P=0.08). Conclusion: Low-dose coronary CT combined with IMR has lower noise and higher signal-to-noise ratio, which is beneficial to the display of coronary stent cavity.

Objective: To investigate the influence of iterative reconstruction(SAFIRE) combined with virtual non-enhanced(VNE) scan on image quality of gastric wall and radiation dose of dual-energy CT(DECT). Methods: 50 patients underwent abdominal DECT scan. The SAFIRE images in arterial phase and portal phase were reconstructed. The VNE images(VNEaS, VNEpS) in arterial phase and portal phase were obtained from SAFIRE image post-processing. Subjective evaluation(Image quality score), objective evaluation[CT value, signal to noise ratio (SNR), background noise, contrast noise ratio (CNR)] and radiation dose[volume CT dose index(CTDIvol), effective radiation dose(ED)] of true nonenhanced(TNE), VNEaS and VNEpS images were compared. Statistical analyses were performed using the random block analysis, the Friedman test, the Wilcoxon test and the paired t-test. Results: There were no significant differences in mean CT values and background noise of gastric wall and erector spinae among three groups of images(all P>0.05). The CT values of liver and abdominal aorta in VNEaS and VNEpS images were higher than that in TNE images(all P<0.05). The SNR of gastric wall, liver, abdominal aorta, and erector spinae in TNE images were higher than that in VNEaS and VNEpS images(all P<0.05). The CNR of gastric wall and erector spinae in TNE, VNEaS images were higher than that in VNEpS images(all P<0.05). However, the image quality of VNEaS images was lower than that of TNE images, and was higher than that of VNEpS images. The effective dose for triple-phase was (23.79±6.00)mSv, and that for dual-phase was(17.51±4.72)mSv. The dose saved by removing the TNE was 6.28 mSv (26.39%). Conclussion: The SAFIRE combined with VNE can provide comparable image quality to TNE images in gastric wall scanning, which could reduce patients’ radiation dose as well. The image quality of arterial phase is superior to that of the portal phase.
