Because clinical symptoms frequently overlap - such as epicondylitis, distal biceps tendon injury, cubital tunnel syndrome, and olecranon bursitis - precise imaging is essential for accurate diagnosis and targeted management. Ultrasonography has become a first-line modality for elbow evaluation due to its high-resolution visualization, dynamic capability, and real-time interventional guidance. This article presents the Ultrasound Musculoskeletal Workshop in Taiwan (USMSIT)/Neuromuscular Ultrasound Workshop in Taiwan (NMUSIT) Fundamental Guide on Diagnostic and Interventional Elbow Ultrasonography, a standardized compartment-based protocol developed within the educational framework of the USMSIT and the NMUSIT. The guide systematically describes probe positioning, key anatomical landmarks, and normal sonoanatomy for assessment of the common extensor tendon, anterior joint recess, distal biceps tendon, common flexor tendon, cubital tunnel, and posterior elbow structures. Representative sonographic features of common pathologies - including tendinopathy, partial tear, joint effusion, ulnar neuropathy, and olecranon bursitis - are outlined, with emphasis on Doppler evaluation and dynamic maneuvers. In addition, step-by-step ultrasound-guided interventional techniques are summarized, including tendon injection, joint aspiration, ulnar nerve hydrodissection, and bursal aspiration. By integrating diagnostic and therapeutic principles within a structured framework, this guide provides a practical and reproducible reference for clinicians performing elbow ultrasonography.","PeriodicalId":45466,"journal":{"name":"Journal of Medical Ultrasound","volume":"34 3","pages":"283-292"},"PeriodicalIF":1.3,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13674881/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149217026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LUS has been validated as a highly accurate technique for both qualitative diagnosis and quantitative assessment of alveolar-interstitial pathologies. Although B-lines can be detected in a variety of pulmonary conditions, characteristic variations in the pleural line provide valuable clues for differential diagnosis. In cardiogenic pulmonary edema, the pleural line appears smooth, reflecting the homogeneous distribution of fluid within the subpleural interstitium and interlobular septa. In contrast, in interstitial lung disease, the pleural line is often irregular - a finding not necessarily attributable to pleural pathology itself, but possibly related to subpleural interstitial abnormalities. These commonly misunderstood aspects underscore the need for clarification in this article, which utilizes an in vitro teaching phantom to explore the formation of such artifacts.","PeriodicalId":45466,"journal":{"name":"Journal of Medical Ultrasound","volume":"34 3","pages":"387-394"},"PeriodicalIF":1.3,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13674884/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149216892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fetal biometry and conventional color Doppler parameters such as resistivity index have been used to diagnose FGR in pregnancies since decades. However, such Doppler parameters are indirect evidences of FGR. Microvascular (MV) flow is a new and upcoming doppler flow imaging technique and can be used to assess placental microvasculature. Vascular index (VI) is a quantitative parameter which can be derived from MV flow imaging. This study aims to use VI as a parameter to differentiate between FGR and non-FGR fetuses in pregnancies.Methods: Sixty two pregnant women with singleton pregnancies was conducted having gestational age between 11 and 40 weeks. 14 FGR pregnancies were studied. Imaging was performed on Samsung V7 machine with a curvilinear probe of frequency 1-7 MHz.Results: The study established that the mean placental VI values in FGR fetuses was significantly lower than non FGR fetuses at all placental locations namely upper, middle and lower parts measuring 31.10 +/- 4.25 v/s 45.01 +/- 7.69, 28.65 +/- 3.24 v/s 45.21 +/- 6.36 and 28.08 +/- 4.29 v/s 45.88 +/- 6.77 respectively.Conclusion: The study establishes the utility of MV flow in distinguishing FGR and non-FGR fetuses using placental VI as a quantitative measure.

Owing to the knee's complex anatomy and its essential role in weight bearing and locomotion, an accurate diagnosis of knee disorders remains challenging. Although radiography and magnetic resonance imaging are indispensable for structural evaluation, musculoskeletal ultrasound (US) has gained recognition as an effective first-line imaging modality because of its real-time visualization, dynamic assessment capability, absence of ionizing radiation, and cost-effectiveness. This guideline follows the EURO-MUSCULUS/USPRM framework to present a standardized, anatomy-based approach to knee ultrasonography, with emphasis on optimal patient positioning and systematic examination of the anterior, medial, lateral, and posterior compartments. Key anatomical structures - including the suprapatellar recess, quadriceps and patellar tendons, medial/lateral collateral ligaments, menisci, iliotibial band, posterior cruciate ligament, and the semimembranosus-gastrocnemius bursa - are detailed alongside their corresponding sonographic landmarks. Common knee pathologies, such as joint effusion, synovial hypertrophy, tendinopathy, ligament and meniscal tears, iliotibial band syndrome, and Baker's cysts, are illustrated with characteristic grayscale and Doppler US features. In addition, practical guidance on US-guided knee interventions, including suprapatellar joint injection, bursal injections, and Baker's cyst aspiration, is provided. By integrating standardized scanning protocols with interventional techniques, this guideline seeks to improve diagnostic reproducibility, enhance recognition of common knee pathologies, and promote the routine clinical adoption of musculoskeletal US in knee assessment.","PeriodicalId":45466,"journal":{"name":"Journal of Medical Ultrasound","volume":"34 3","pages":"273-282"},"PeriodicalIF":1.3,"publicationDate":"2026-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13674891/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149217034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transvaginal 3D power Doppler ultrasound was performed before and after treatment to evaluate fibroid and uterine volumes, the vascularization index (VI), vascularization flow index (VFI), pulsatility index (PI), and resistance index.Results: Three months of UPA therapy significantly reduced dominant fibroid volume (69.5 → 34.4 cm3, P = 0.008), uterine volume (156.6 → 78.0 cm3, P = 0.035), fibroid VI (1.47 → 0.44, P = 0.016), and VFI (0.62 → 0.26, P = 0.028).

However, the US is not readily available in many clinical settings. This study aimed to establish practical margins for needle insertion into the rhomboid major to guide practice when US is not accessible.Methods: Healthy volunteers were recruited from January 2021 to August 2021. Anthropometric data were collected, and participants were classified into three body mass index (BMI) subgroups (<23, 23-24.9, >25 kg/m2). US examinations were performed in the sitting position. The rhomboid major was divided into two regions (A1, A2), skin-to-rhomboid (SR), rhomboid thickness (RT), and skin-to-pleural (SP) distances were measured bilaterally. Safe margins were defined as mean - 2 or 2.5 standard deviation of SP. Analyses included descriptive statistics, intraclass correlation coefficients (ICCs), t-tests, regression, and Pearson's correlation.Results: Eighty-four volunteers participated (43 males, 41 females; mean age 38.0 ± 10.7 years). Intrarater reliability was excellent (ICC 0.921-0.974). No side-to-side differences were observed. SR and SP distances increased significantly, and RT was thicker with higher BMI (P < 0.001). At A1, SR measured 13.2 ± 2.4 mm (normal), 15.7 ± 2.5 mm (overweight), and 19.1 ± 3.5 mm (obese); at A2, 11.1 ± 2.4, 13.9 ± 2.5, and 17.3 ± 3.6 mm, respectively. SR and SP correlated strongly with BMI (r = 0.733-0.793).
