Hence, this study aims to investigate the diagnostic accuracy of transcranial ultrasonography for detecting stenosis in acute ischaemic stroke patients.Material and methods: We systematically reviewed the databases such as CINAHL, SCOPUS, EMBASE, MEDLINE, Cochrane Library, Google Scholar, and ScienceDirect from inception till June 2023. Studies were eligible if they compared the diagnostic role of transcranial ultrasonography with established techniques, and reported accuracy parameters such as sensitivity, specificity, positive and negative likelihood ratios. Subgroup analysis was performed for TCD and TCCD/TCCS.Results: Seventeen studies involving 1496 participants were included. The pooled sensitivity and specificity of transcranial ultrasonography were 90% and 95% respectively. For TCD, the sensitivity and specificity were 87% and 93% respectively. TCCD/TCCS showed sensitivity 98% and specificity 97%. High clinical value was evident in both TCD and TCCD/TCCS, with heterogeneity across studies but no observable publication bias.Conclusion: Transcranial ultrasonography, including both TCD and TCCD/TCCS, demonstrates high diagnostic accuracy in detecting stenosis in patients with acute ischaemic stroke. These findings support the utility of these methods as reliable, non-invasive tools for cerebrovascular assessment.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484564","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}

The scans were conducted both with and without a bowel preparatory protocol (BPP).Results: The highest concordance was observed in the group 4, which included patients with RSE and BPP, with a Kappa value of 0.47-0.52. In contrast, for groups with MRI scans without the BPP, there was no consistency among the investigators (Kappa <0.20). The sensitivity, specificity, positive predictive value, and negative predictive value were 0.72, 0.47, 0.72, and 0.47 without BPP, and increased to 0.82, 0.74, 0.85, and 0.74, respectively, after BPP.Conclusions: The results reveal that the concordance between investigators in detecting RSE via MRI scan improves with the use of BPP. Additionally, the success rate of MRI and TVUS for detecting RSE can be comparable, but only if bowel preparatory techniques are utilized during MRI scans.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484568","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}

To gain deeper insights into the research landscape of ultrasound in breast cancer diagnosis, this study employed bibliometric methods for a comprehensive analysis spanning from 2004 to 2024, analyzing 3523 articles from 2176 institutions in 82 countries/regions. Over this period, publications on ultrasound diagnosis of breast cancer showed a fluctuating growth trend from 2004 to 2024. Notably, China, Seoul National University and Kim EK emerged as leading contributors in ultrasound for breast cancer detection, with the most published and cited journals being Ultrasound Med Biol and Radiology. The research spots in this area included \"breast lesion\", \"dense breast\" and \"breast-conserving surgery\", while \"machine learning\", \"ultrasonic imaging\", \"convolutional neural network\", \"case report\", \"pathological complete response\", \"deep learning\", \"artificial intelligence\" and \"classification\" are anticipated to become future research frontiers. This groundbreaking bibliometric analysis and visualization of ultrasonic breast cancer diagnosis publications offer clinical medical professionals a reliable research focus and direction.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484569","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}

Fewer studies were performed investigating the prognostic relevance using transient elastography (TE), although with promising results. This study was designed to evaluate the prognostic relevance of ARFI elastography.Material and method: Patients receiving ARFI elastography in our ultrasound department between 2010 and 2012 were initially screened for an ARFI examination with a clinical follow-up of at least 5 years. The following events were recorded: liver related death, liver unrelated death, HCC, liver decompensation/ variceal bleeding.Results: A total of 335 patients were included in the final analysis with an ARFI examination of the liver and a follow-up of 60 months. Within the observation interval the number of events with corresponding AUROCs (shown with 95% confidence interval) were: overall death (n=49, 0.76 [0.69 - 0.83]), liver related death (n=25, 0.85 [0.77 - 0.93]), liver unrelated death (n=24, 0.66 [0.55 - 0.77]), HCC (n=15, 0.80 [0.72 - 0.87]), liver related complications/variceal bleeding (n=34, 0.87 [0.82 - 0.93]). In the group of patients with ARFI values suggestive of cirrhosis (equal to or above 1.80 m/s; n=110) higher values (<2.5 m/s vs. >= 2.5 m/s) where associated with a significant decline in liver related survival (p=0.007).Conclusion: ARFI elastography seems to have a good diagnostic accuracy for the prediction of liver related death and decompensation. Further it seems to allow a risk stratification in patients with cirrhosis suspicious elastography values.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484561","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}

Endoscopic ultrasound (EUS) has advantages of transmural, close range and real-time imaging. Under its guidance, minimally invasive endoscopic removal of FBs and abscess drainage become available and safe to avoid unnecessary surgery. However, relatively few diagnostic applications of EUS have been reported. Endoscopic removal and abscess drainage with or without EUS-guidance were even scarce. We found 21 cases of migratory FBs reported in which EUS was used to diagnose and/or treat including our case. We further summarized clinical characteristics and EUS manifestations of embedded or migratory FBs for future differentiation, and treatment strategies by endoscopy and EUS. EUS is a valuable tool in recognizing and differentiating embedded or migratory FBs. EUS-guided endoscopic removal is a minimally invasive, safe and innovative solution. EUS with novel device also assists in sufficient and secure drainage for FBs related abscess collections. A multidisciplinary team consult is sometimes mandatory for complicated cases. This would break a conceptual barrier in therapeutic endoscopy.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484565","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}
