Clinical data, ultrasound features, and pregnancy outcomes were analyzed.Results: In this study, a total of 23 pregnant women were included. Of these, eight were diagnosed in early pregnancy, and 15 were diagnosed in mid-pregnancy. Seven participants had concurrent uterine fibroids, 10 had a history of abdominal or pelvic surgery, and two had ovarian cysts. A total of 13 cases presented with symptoms of urethral obstruction, three with rectal pressure symptoms, five cases with tight and stiff lower abdomen and two cases without special discomfort. Seventeen cases exhibited cervical compression with thinning and elongation, measuring approximately 39 to 73 mm. All 23 cases underwent manual or knee-chest positioning repositioning, with one case requiring surgical intervention. Ultimately, 22 cases resulted in full-term live births, one case experienced fetal demise at 24 weeks and one case experienced gravid uterine incarceration again in the third week after successful manual reduction, and manual reduction was performed again.Conclusion: Early diagnosis is critical for obstetric management and clinical prognosis, facilitating the successful release of the incarcerated uterus. The earlier the diagnosis, the higher the likelihood of successfully releasing the incarcerated uterus.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142307760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dynamic myocardial perfusion images were captured during rest and peak dobutamine stress from various angles, analyzing parameters like plateau value A, slope β, and the product A × β, reflecting different aspects of myocardial blood flow.Results: Parametric values of myocardial perfusion (PVMPs) were significantly lower in group D at rest compared with other groups (p < 0.001). PVMPs increased notably at peak dobutamine stress in groups A, B, and C (p < 0.001). Groups A and B had higher PVMPs than groups C and D, with group D significantly lower (p < 0.001). β reserve values decreased gradually from group A to D, with significantly lower values of A and A × β in groups C and D compared with A and B (p < 0.001). Sensitivity and specificity for predicting >70% coronary artery blockage was 80%, 66%, and 74%, 80%, respectively, using specific thresholds.Conclusion: Combining MCE with DSE is highly sensitive and accurate in diagnosing obstructive coronary artery blockages. It also helps assess myocardial microcirculation perfusion and left ventricular reserve function, which decline with increasing severity of coronary artery blockage.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142288248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All cesarean cases were first operational delivery with lower uterine incision, repaired with double-layer suture. At 1 and 4 weeks postpartum, the uterus was delineated using transvaginal ultrasonography with superb microvascular imaging. Separate regions of interest were created for anterior myometrium of the isthmus and the body. The microvascular flow profile in three circular sampling points placed in a region of interest was quantified and expressed as vascular density. The vascular density ratio of the uterine isthmus to the body was compared between one and four weeks for both groups. Wilcoxon's signed-rank test was used to assess statistical significance (set at p < 0.05).Results: In cesarean deliveries, the vascular density ratio of the uterine isthmus to the body increased from 1 (median: 0.51, range: 0.30-0.68) to 4 weeks (0.99, 0.85-1.60), whereas no changes were noted in transvaginal deliveries.Conclusion: Superb microvascular imaging can effectively measure myometrial microvascular blood flow recovery at cesarean incision sites, indicating its potential as a tool for monitoring postpartum wound healing.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142288250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasonography is frequently used for follow-up of symptomatic gynecomastia. Shear wave elastography (SWE) is an auxiliary tool for the diagnosis of breast disorders. Our aim is to evaluate SWE properties of breast tissue in PG.Methods: Fifty consecutive adolescents, aged 10-18 with a diagnosis of gynecomastia were prospectively included in the study. Following clinical and laboratory evaluation, participants underwent B-mode ultrasound and classified as nodular, dendritic, and diffuse pattern. SWE and hormonal values of all groups were recorded. Then, statistical analysis was performed.Results: Briefly, 92 breasts (43 left and 49 right; 42 bilateral and 8 unilateral) were included in the analyses. There were no significant differences in clinical parameters including age, BMI-SDS, estradiol (E2), testosterone (T), and E2/T levels within groups (p > 0.05). Breast volume and SWE levels were significantly different in all groups (p < 0.05). SWE values were significantly lower for those of dendritic pattern than in nodular pattern (p < 0.05). ROC analysis revealed that for the best the cut-off value of 13.7 kPa, area under the curve value was 0.922 with 84% sensitivity and 87% specificity.Conclusions: SWE values were significantly lower in patients with dendritic gynecomastia than those with nodular gynecomastia. Knowledge of the SWE values for the initial diagnosis and follow-up values could help avoid unnecessary interventions.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142288240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Relative risks for a low-positioned placenta in the third-trimester were calculated for women with posterior versus anterior, low-lying placenta versus placenta previa and positive versus negative history of cesarean section. Multilevel likelihood ratios and corresponding ROC curves for different ranges of IOD were calculated.Results: Women with posterior placenta had a high risk of low positioned placenta compared to anterior placenta (9.28% vs. 0.74%); RR 1.45, similarly women with placenta previa had high risk compared to low lying placenta (68.57% vs. 1.69%); RR 6.51, so did the women with previous cesarean section (9.41% vs. 5.87%); RR 1.47.Conclusions: 93.42% placenta which were low positioned in mid trimester were normally situated in third trimester. The cut-off for IOD in anterior placenta was -40 mm and in posterior placenta was 14.3 mm. IOD measurement and interpretation seems promising.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142288246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
