Electromyography and nerve conduction studies do not allow precise localization of the lesion and differentiation between lesions in continuity and non-continuity in cases with complete axonotmesis. Improved ultrasound technology allows the examination of almost the entire peripheral nervous system. The complex sono-anatomy of the brachial plexus outside of the standard scanning planes makes it difficult to access this region.Methods: On the basis of the Visible Human Project of the National Institutes of Health (NIH), multiplanar reconstructions were created with the 3D Slicer open-source software in the various planes of the ultrasound cross-sections. The ultrasound examination itself and the guidance of the ultrasound probe in relation to the patient were recorded as video files and were synchronized through the audio channel. Subsequently, image matching was performed.Results: Multiplanar reconstructions facilitate visualization of anatomical regions which are challenging to access thereby enabling physicians to evaluate the course of the peripheral nerve of interest in dynamic conditions. Sonographically visible structures could be reproducibly identified in single-frame analysis.Conclusion: With precise knowledge of the ultrasound anatomy, the nerve structures of the brachial plexus can also be dynamically assessed almost in their entire course.

Placental insufficiency can cause a variety of obstetric complications. Despite the many efforts to enhance diagnosing placental insufficiency, no imaging technique has proven satisfactory. A promising imaging technique is contrast-enhanced ultrasound (CEUS) using microbubbles which has proven capable of (micro)vascular imaging. Its use for placental vascularization assessment in human pregnancies remains constrained by limited evidence and safety concerns. This scoping review aims to demonstrate the safety of CEUS used in human pregnancy in the published literature to date.Material and methods: A systematic search using PubMed, Medline, Embase, and Cochrane databases was performed. All studies where contrast-enhanced ultrasound was used in pregnant humans were included. Studies, where there was a planned termination of pregnancy, were excluded. To assess the safety of CEUS during pregnancy, relevant outcomes were divided into the following 3 categories; fetal outcome, maternal outcome, and pregnancy and neonatal outcomes.Results: A total of 13 articles were included, in which 256 women underwent CEUS during pregnancy. No clinically significant maternal or fetal adverse events or negative pregnancy or neonatal outcomes associated with CEUS were described.Conclusion: Based on our findings, we consider expanding the knowledge of this promising diagnostic technique in future larger clinical studies to be safe and relevant.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141447444","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 ultrasound characteristics, clinical treatment, and pregnancy outcomes of patients with HIMPs were evaluated.Results: Eight women with HIMPs were included. Among them, 6 patients were diagnosed by transvaginal sonography, and 2 patients were misdiagnosed with heterotopic interstitial pregnancy. The diagnostic accuracy was 75% (6/8). Five patients with HIMPs were diagnosed at the time of the initial scan (5+6-6+3 weeks). An intramural gestational sac was observed in all 6 patients, and an embryo with cardiac activity was detected in one patient on the follow-up scans. Intrauterine pregnancies (IUPs) were revealed in all 6 patients, and embryo(s) with cardiac activity were observed in 5 patients at the time of the initial diagnosis or later. The patients receiving expectant treatment all presented with bagel signs, while patients with embryos with cardiac activity all underwent surgery. Among the 6 diagnosed women, 1 patient was initially treated medically, 4 were treated expectantly, and 1 was treated surgically. Among the 6 diagnosed patients, the IUPs of 5 patients resulted in live infants.Conclusion: Single ET should be recommended to decrease the possibility of HIMP. An accurate diagnosis of HIMP was reached in most cases by detailed ultrasound early in the first trimester. Most IUPs of HIMPs seem to have good outcomes with timely and proper management. Expectant management might be a possible choice for nonviable intramural pregnancies.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142074381","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}

It was assumed that when disruptions occur in the process of somitogenesis during membranous vertebral body formation, chondrification and ossification will follow the anomalous membranous vertebral body scaffolding, resulting in an anomalous vertebral formation, such as a hemivertebra. Another hypothesis is that hemivertebra may result from anomalous distribution of intersegmental arteries of the vertebral column. There is no description in the medical literature of \"excess linear calcifications\" of part of the fetal vertebra, characterized by the presence of linear calcifications in the vertebrae of a developing fetus. In the first two trimesters of pregnancy, the fetal vertebrae usually show three calcified points in an axial section: the vertebral body and two transverse processes. Premature linear vertebral calcification was defined as an anterior or posterior echogenic connection between two of the points (Fig. 1). In this study, we describe seven cases of premature fetal linear vertebral calcification.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142037472","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}

Even though both techniques measure liver stiffness, their numerical results often diverge. Confounders and reliability criteria for 2D-SWE have not been systematically investigated.Materials and methods: We prospectively recruited participants with paired LSM by VCTE and the novel 2D-SWE technique ElastQ (Philips) in three European tertiary centers. The following parameters were recorded: sex, age, body mass index (BMI), etiology, laboratory markers of liver damage and function, as well as cholestasis, LSM by VCTE and controlled attenuation parameter (CAP), interquartile range (IQR)/median for VCTE-LSM and ElastQ-LSM, and the skin-to-liver capsule distance.Results: We included 840 participants: 447 (53.2%) males; median age 57.0 [IQR:19.0] years; median BMI 25.4 [6.0] kg/m2; median VCTE-LSM 7.25 [9.2] kPa; median ElastQ-LSM 6.7 [5.4] kPa. On uni- and multivariable modeling (adjusted for LSM), we found that the discrepancy increased with liver stiffness and markers of disease severity. Skin-to-liver capsule distance and BMI affected VCTE-LSM more compared to ElastQ-LSM and significantly increased the discordance between the two measurements.Conclusion: The discrepancy of ElastQ-LSM to VCTE-LSM increases with liver stiffness and disease severity. BMI and skin-to-liver capsule distance increase the discrepancy between VCTE- and ElastQ-LSM but affect ElastQ-LSM less. The quality criterion IQR/median ≤ 30% indicates reliable ElastQ-LSM.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141908161","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}

As a comparison, clinical investigations were performed by two experienced ultrasonographers by measuring the resolution of anatomical structures in the liver, pancreas, and intestine in ten subjects.Results: Axial full width at half maximum resolution (FWHM) of 100µm phantom pins at depths between one and twelve cm ranged from 0.6-1.9mm without correlation to pin depth. Lateral FWHM resolution ranged from 1.3-8.7mm and was positively correlated with depth (r=0.6). Axial and lateral resolution differed between devices (p<0.001) with the lowest median lateral resolution observed in the E10 (5.4mm) and the lowest axial resolution (1.6mm) for the IQ+ device. Although devices showed no significant differences in most clinical applications, ultrasonographers were able to differentiate a median of two additional layers in the wall of the sigmoid colon and one additional structure in segmental portal fields (p<0.05) using cartwheel devices.Conclusion: While handheld devices showed superior or similar performance in the phantom and routine measurements, workstations still provided superior clinical imaging and resolution of anatomical substructures, indicating a lack of objective measurements to evaluate clinical ultrasound devices.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":"405-411"},"PeriodicalIF":3.1,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11293899/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140013483","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}

SBT can provide a realistic and focused learning experience that creates a deep and immersive understanding of the complexity of ultrasound, including enhancing knowledge and confidence in specific areas of interest. Abdominal ultrasound simulation is a tool to increase patient safety and can be a cost-efficient training method. In this paper, we provide an overview of various types of abdominal ultrasound simulators, and the benefits, and challenges of SBT. We also provide examples of how to develop SBT programs and learning strategies including mastery learning.
