Thirteen eligible studies published up to May 3, 2025, were obtained through a comprehensive search. We conducted a meta-analysis using a random-effects bivariate model to investigate the diagnostic accuracy of the ultrasound HRI in assessing hepatic steatosis. A total of 1496 cases were included that used liver biopsy or MRI-PDFF as the reference standard to determine the presence of hepatic steatosis. We synthesized the sensitivity, specificity, likelihood ratio, diagnostic advantage ratio, and area under the curve of the included studies to assess the performance of the HRI as a diagnostic tool. The meta-analysis demonstrated that ultrasound HRI had good performance in evaluating hepatic steatosis. However, there were significant differences in diagnostic performance and optimal cut-off values among the included studies, indicating the need for consensus on the optimal cut-off value for diagnosing hepatic steatosis. As an auxiliary means of ultrasonic analysis, ultrasonic HRI has achieved a good diagnostic effect in detecting hepatic steatosis.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144804201","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 patients were examined by preoperative CEUS and postoperative Ki-67 immunohistochemistry. Divided by the cut-off of the Ki-67 labeling index, HCC patients were assigned into the low (n = 46) and high Ki-67 expression groups (n = 48). Clinical data and imaging features of CEUS were compared between groups. Finally, a CEUS-based model in predicting abnormal Ki-67 expression in HCC was created.Results: Significant differences showed in the age of onset, alpha fetoprotein (AFP), des-gamma-carboxy prothrombin (DCP), number of lesions, maximum diameter, peripheral hypoechoic halo, boundary, morphology, serrated edge, and internal necrosis between groups (p < 0.05). TIC analysis showed significant differences in the ascending slope (AS), half of the decay time (DT/2), descending slope (DS) and area under the curve (AUC) between groups as well (p < 0.05). Multivariate logistic regression analysis revealed that the number of lesions (OR = 3.845, 95% CI 1.315-11.248, p = 0.014), maximum diameter (OR = 1.064, 95% CI 1.030-1.098, p < 0.001), boundary (OR = 7.017, 95% CI 1.638-30.072, p = 0.009), and morphology (OR = 5.970, 95% CI 1.154-30.879, p = 0.03) were significantly correlated with Ki-67 expression in HCC patients. DS was negatively correlated with Ki-67 expression (OR = 0.000, 95% CI 0.000-0.108, p = 0.013). The AUC of the CEUS-based prediction model was 0.949 (95% CI 0.906-0.992).Conclusions: CEUS images plus TIC analysis provide valuable information to predict preoperative Ki-67 expression in HCC patients, thus favoring clinical management to improve patients' prognosis.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144799245","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}

Ultrasound features, including plaque echogenicity (PE), plaque ulceration (PU), juxtaluminal black area (JBA), normalized wall index (NWI), and lumen stenosis rate (LSR), among others, were systematically recorded. Logistic regression and receiver operating characteristic (ROC) curve analyses were conducted to evaluate the diagnostic and predictive value of these features for IPH.Results: PU, JBA, and NWI were identified as independent risk factors for intraplaque hemorrhage (IPH), with odds ratios (ORs) of 7.43 (95% CI: 2.15-25.67, p = 0.002), 4.90 (95% CI: 1.42-16.92, p = 0.012), and 2.55 (95% CI: 1.19-5.45, p = 0.016), respectively. Among individual predictors, NWI showed the highest diagnostic performance, with an area under the curve (AUC) of 0.78 (95% CI: 0.67-0.89). A combined diagnostic model incorporating PU, JBA, and NWI significantly improved performance, achieving an AUC of 0.86 (95% CI: 0.77-0.95), a sensitivity of 81.82%, and a specificity of 78.38%.Conclusion: Ultrasound imaging features, particularly PU, JBA, and NWI, are valuable predictors of IPH in carotid atherosclerotic plaques. Combined analysis of these features significantly enhances diagnostic accuracy. These findings underscore the potential of ultrasound as a cost-effective, noninvasive modality for early IPH detection and stroke risk assessment.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144804199","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}

Based on the pregnancy outcomes, the prenatal cases were divided into two groups: the AS group and the false-positive group. Electronic spatiotemporal image correlation (eSTIC) technology was used to measure AV and PV of all fetuses, and the AV and PV Z scores, along with the PV/AV ratio, were calculated, compared, and analyzed.Results: In the AS group, significant differences were found between the first and second echocardiograms regarding the AV Z score, PV Z score, and PV/AV ratio. In the false-positive group, only the PV Z score and PV/AV ratio showed significant differences. In the first echocardiogram, the AV Z score and PV/AV ratio significantly differed between the AS and false-positive groups. In the second echocardiogram, only the AV Z score showed differences. An AV Z score < -2.46 showed high sensitivity (89.5%) and specificity (100%) for AS diagnosis.

Participants underwent QUS and magnetic resonance imaging of the proton density fat fraction (MRI-PDFF), the reference standard. A multivariable regression model was developed using two QUS parameters. Linear regression was used to estimate fat fraction, with adjusted R2 values assessing model fit. The diagnostic performance of USFF for hepatic fat content thresholds (≥ 5%, ≥ 10%, ≥ 20%) was evaluated using the area under the receiver operating characteristic curve (AUC).Results: The development set included 427 South Korean participants, while the validation set comprised 100 from Hungary and 79 from Italy. R2 values were 0.689, 0.702, and 0.485 for the development, internal validation, and external validation sets, respectively.
