AGD wasdefined as an increase in serum creatinine levels of at least 25% compared to the baseline of the last three months. The control group consisted of patients with stable kidney graft function (SGF). The top five CEUS parameters that achieved the best discrimination between the AGD and SGF groups were selected based on ANOVA testing and then employed as input for training MLA (naïve Bayes (NB), k-nearest neighbors (k-NN), and logistic regression (LR)). The models were validated by leave-one-out cross-validation.Results: Among the 111 CEUS analyses, 21 corresponded to the AGD group and 90 to the SGF group. CEUS analyses yielded 44 parameters, from which five were selected: the wash out rate in segmental arteries,time to peak in segmental arteries, medullary mean transit time, renal mean transit time, and medullary time to fall. These five parameters were employed as input for MLA, yielding an AUROC of 0.68 for NB and k-NN and 0.72 for LR. The inclusion of graft survival in the MLA significantly improved discrimination accuracy, yielding an AUROC of 0.79 for NB, 0.76 for k-NN,and 0.81 for LR.Conclusions: The use of MLA represents a promising strategy for analyzing CEUS-derived parameters in the setting AGD.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142134949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to analyze the characteristics of conventional ultrasound (US) and contrast-enhanced ultrasonography (CEUS) in HEHE.Material and methods: This multi-center case series study enrolled patients diagnosed with HEHE from five hospitals in China between August 2004 and October 2022. Data on conventional US and CEUS characteristics were collected and analyzed.Results: A total of 41 patients with HEHE were included, comprising 14 males and 27 females with a mean age of 50.62±11.43 years. The mean size of the lesion was 4.51±2.92 cm. Among these patients, 29 were confirmed through surgical resection and 12 through liver biopsy. Conventional US imaging identified three types of HEHE: multifocal type in 35 patients (85.4%), single nodular type in 1 patient (2.4%), and giant type in 5 patients (12.2%). US revealed proximity to the liver capsule in 29 patients (71%), hypoechoic appearance in 36 patients (88%), heterogeneity in 4 patients (10%), and hyperechoic appearance in 1 patient (2.4%). CEUS also demonstrated three distinct enhancement patterns: peripheral marginal enhancement with centripetal filling in the arterial phase and washout in the portal venous and venous phases (23 patients), eterogeneous enhancement in the arterial phase with washout in the subsequent phases (7 patients), and mild hyperenhancement in the arterial phase with resolution in later phases (9 patients). A hypo-enhancement pattern in the portal venous and venous phases was observed in 38 patients, suggesting a higher degree of malignancy.Conclusion: HEHE exhibits specific US findings, primarilypresenting as multiple hypoechoic lesions distributed under the liver capsule.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142134953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These scans received an instant review by experts. The discrepancy rates of the resident radiologists were evaluated using expert diagnoses. Then, the plaque detection rate of the resident radiologists was investigated for different plaque characteristics. The causes of incorrect stenosis diagnoses were analyzed.Results: In the investigation of carotid plaque detection, a total of 274 carotid scans from 137 patients were evaluated in our hospital. The overall agreement rate of plaque detection was 90.9%. Echolucent plaques, plaques in the lateral or near wall, and plaques in the carotid bulbs were more likely to be misdiagnosed by resident radiologists. A total of 325 plaques were included in the investigation of carotid artery stenosis classification. The overall agreement rate of stenosis evaluation was 67.7%. The misclassification of moderate stenosis was greater than that of mild and severe stenosis (p=0.0003). The sensitivity was as low as 55.56%. Nonstandard sonographic techniques and incorrect application of interpretive criteria were two main causes.Conclusions: Resident radiologists could accurately and efficiently detect carotid plaques. Scanning by resident radiologists can expand access to ultrasound services. Only the diagnosis of moderate stenosis by resident radiologists was not satisfactory and may require a specialized review from experienced radiologists.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142134950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Revascularization reduces symptoms, amputation rate and increases the chances of social reintegration. Our aim was to evaluate the benefits of vascular duplex ultrasonography (DUS) for identifying patients suitable for direct percutaneous transluminal angioplasty (PTA) without the need for a prior angiography.Material and methods: We included in the study 251 patients with PAD evaluated by DUS. Depending on the DUS findings the patients were split in two groups: group I, 143 patients (57%), in which selective angiography and direct PTA was performed and group 2, 108 patients (43%), in which invasive arteriography was considered necessary prior to a decision for revascularization. Results: The first group had a similar success rate (92.3% vs. 86.1%; p=0.111), but with a reduction in radioscopy time (minutes) (17.2 vs. 20.8; p=0.013), iodine contrast volume (ml) (190 vs. 227.5; p<0.001), days of hospitalization (4 vs. 7; p<0.001) and by 44.75% (p<0.001) of hospitalization costs when compared to the second group.Conclusions: DUS allows the optimal selection of patients who can benefit from direct PTA.

Univariate analysis and binary logistic regression analysis of the influencing factors were conducted to identify LAMN and ASA. The AUROC was calculated to analyze the diagnostic efficacy of these independent factors. A four-grid table was established to determine the diagnostic efficacy of the ultrasound marks for diagnosing LAMN.Results: Patient age and appendix short diameter in the LAMN group were found to be significantly higher than those in the ASA group. The neutrophil ratio and thickness of the appendix wall in the LAMN group were significantly lower than they were in the ASA group. Patient age (OR=1.112, p=0.015) and appendix short diameter (OR=1.476, p=0.008) were independent risk factors for LAMN. The AUROCs for age and short diameter were 0.898 [95% CI: 0.807, 0.956] and 0.953 [95% CI: 0.879, 0.988], respectively.
