For solid masses, both the intralesional and the peripheral vascularization was analyzed and quantified by MI and then compared to peak enhancement on CEUS. Regarding cystic lesions, we evaluated the presence or absence of vascularization within the cystic wall and/or septa. MI results were compared with CEUS findings using Pearson's Chi square test. An optimal size cut-off for renal lesions was determined with the Youden test.For solid lesions, a statistically significant correlation (p <0.05) was observed between the MI parameters and the peak enhancement on CEUS. The detection rate (DR) for lesional vascularization on MI was 87.5%, while if we consider only lesions larger than the optimal cut-off (14mm), the DR increases to 98%. In cystic lesions, the MI showed a high specificity (93.9%) in predicting CEUS results and a high positive predictive value (84.2%). The concordance was 100% in Bosniak I lesions and 80% in Bosniak IV lesions, while it was lower for the other classes. Furthermore, we found a statistically significant correlation (p <0.05) between Bosniak grade and lesional vascularity on MI.Our preliminary study shows that MI cannot replace CEUS, but could reduce its use, especially in solid lesions larger than 14mm and in cysts classified as Bosniak IV, a goal that is particularly important in an active surveillance setting.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":"75-85"},"PeriodicalIF":2.9,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143754913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the impact of the OvAi denoising algorithm on IOTA color score assignment and perceived image quality in adnexal mass ultrasound.In this multicenter prospective study (May 2018-August 2022), color/power Doppler videos of 100 adnexal masses from 100 women were acquired in 2 outpatient clinics. Six experts, 5 moderately experienced, and 8 beginner examiners assessed IOTA color score and image quality before and after applying the denoising algorithm. Interobserver agreement regarding color score assignments was measured using Fleiss' Kappa, and perceived image quality changes were tested via Chi-square.Interobserver agreement regarding color score assignment was fair across all observer groups (κ: 0.296-0.396) and remained unchanged post-denoising. In benign lesions, CS1 increased (+14.9%), while CS2-CS4 decreased. In malignant cases, CS1 and CS2 increased (+76.2% and +30.8%), with a smaller reduction in CS3 (-3.7%) and CS4 (-21.4%). The CS4 decrease was less marked in malignant than in benign lesions (-21.4% vs. -38.3%). A significant improvement in perceived image quality was observed in all observer groups (p < 0.05).The OvAi algorithm improved perceived image quality without significantly impacting interobserver agreement. Continued development may enable more objective and automated color score assignments, potentially reducing interobserver variability and supporting diagnostic reliability.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145240234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assessing hepatic fibrosis is essential in chronic liver disease, and several diagnostic modalities are available. The gold standard remains percutaneous liver biopsy, an invasive method using a 16-18-gauge needle. A breakthrough came in 2003 with transient elastography (TE), a non-invasive technique that measures liver stiffness (kPa) via elastic wave propagation. Later, shear wave elastography (SWE), integrated into modern ultrasound systems, was developed to assess tissue elasticity. SWE generates shear waves (SWs) through acoustic radiation force, assuming tissues to be linearly elastic and homogeneous, and provides quantitative stiffness data. Recent evidence shows hepatic tissue is viscoelastic, with wave propagation varying by frequency. Quantifying viscosity remains a challenge. Fibrosis affects viscoelastic properties and shear wave speed (SWS), while necroinflammation predominantly alters the viscous component, influencing the shear wave dispersion slope (SWDS). This review provides an overview of ultrasound elastography methods, including stiffness and viscosity assessment, their physical principles, and clinical applications in hepatology.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145139250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recommendations follow the three EFSUMB competency levels for medical ultrasound practice. Level 1 describes the skills required to perform basic thoracic ultrasound examinations and basic interventions independently, level 2 includes more advanced transthoracic ultrasound imaging and guided interventions, while level 3 involves the practice of high-level thoracic ultrasound and the use of advanced technologies.

The absence of radiation and the constant on-site accessibility make it the ideal tool for children. However, despite remarkable technical advances in resolution and applicability, many sophisticated medical questions still require profound expertise on the part of the examiner, thus often hampering fast decisions particularly outside regular working hours.This single-center study, at a university children's hospital evaluated the use of US during emergency service. A four-week documentation period was followed by a subsequent eight-week supervision period with live supervision availability on demand guided by a remote US expert. The demand for expert support, diagnosis, grading of urgency, duration and success of examination, and satisfaction of both examiners were analyzed.108 patients (mean age 9.7 years) were included. In 38% of cases, US was supervised on demand with a definite diagnosis in 92.6% of cases (25/27). Image quality and technical performance were graded sufficient in 100% of cases. Supervised compared to non-supervised US examinations were prolonged (14.4 min vs. 7.1 min, p<0.001), were more prevalent within the first 24 h in the hospital (70% vs. 56.8%, p=0.06), and were classified more frequently as emergency (22.2% vs. 2.3%; p=0.015). All participants classified the availability of US supervision as decisively helpful.Remote live supervised pediatric US was feasible and effective. It combined timely, high-quality diagnostics even in the case of challenging medical questions with simultaneous US training.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":"594-602"},"PeriodicalIF":2.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12700712/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142331003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among all congenital heart defects (CHD), conotruncal anomalies are the most common critical heart defects - after ventricular and atrial septal defects. Conotruncal anomalies are anomalies of the infundibulum (conus arteriosus) and great vessels (truncus arteriosus). These anomalies predominantly affect the right ventricular outflow tract and account for about 25-30 % of all CHD cases. Based on their incidence and clinical relevance, this article describes perimembranous ventricular septal defects (VSD), tetralogy of Fallot (TOF), pulmonary atresia with VSD (PAVSD), transposition of the great arteries (TGA), and the less common double outlet right ventricle (DORV) and truncus arteriosus communis (TAC).Conotruncal anomalies are usually associated with a normal 4-chamber view, so the prenatal detection rate during prenatal care tends to be low. However, because undetected conotruncal anomalies have high rates of postnatal mortality and morbidity, in accordance with internationally recommended policies, the foetal heart should always be examined systematically and segmentally in different sectional planes, including the outflow tract and in combination with the color Doppler, to achieve a higher detection rate. This article provides an overview of prenatal sonographic diagnosis of conotruncal anomalies based on extensive imaging material.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":"536-559"},"PeriodicalIF":2.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145024676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prenatal ultrasound-based and MRI-based (MRI: magnetic resonance imaging) observed-to-expected lung-to-head ratio (o/e-LHR) and MRI-based relative fetal lung volume (rFLV) were evaluated and compared. Their prediction component with respect to clinical outcome was evaluated. Mean values were compared by two-sample t-tests or the Mann-Whitney U-test. The Chi-square or Fisher's exact test was used in order to compare qualitative parameters. Kappa coefficients, McNemar test, and Bowker's test were used to assess the degree of agreement.The study population included 183 fetuses with left-sided and 26 fetuses with right-sided CDH. Survival did not differ significantly (74.3% vs. 80.8%, p=0.053). For every imaging technique, incidences of extracorporeal membrane oxygenation (ECMO) and chronic lung disease decreased, and the probability of survival increased gradually reaching minima and maxima for o/e-LHR and rFLV above 35%. Outcome improved if rFLV was above 35% - compared to MRI-based measurement of o/e-LHR above 35%.Our data confirm the predictive value of o/e-LHR for CDH - irrespective of the diagnostic modality. MRI evaluation of o/e-LHR was not superior compared to sonography. MRI evaluation of rFLV correlated with morbidity and mortality which can be beneficial for fetuses with an otherwise good prognosis based on higher o/e-LHR as 2D imaging techniques can underestimate the fetuses' risk for pulmonary hypertension and ECMO.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":"585-593"},"PeriodicalIF":2.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12700711/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143617818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
