Failure to achieve an accurate diagnosis and initiate timely treatment following a rotator cuff injury can result in progressive worsening of the condition, potentially leading to severe complications. In this report, we present a case of post-traumatic supraspinatus tendon injury. By comparing musculoskeletal ultrasound, contrast-enhanced ultrasound, and ultra resolution microscopy (URM) imaging, we demonstrate that URM, as an advanced imaging modality with high resolution, real-time dynamic capabilities, and quantitative analytical potential, offers distinct advantages in detecting rotator cuff injuries. Specifically, URM improves the detection rate, delineates injury boundaries with greater accuracy, and assesses the extent of inflammatory adhesions surrounding the affected site.</p>","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"237-239"},"PeriodicalIF":0.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144048706","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}

Diaphragm ultrasound (DUS) is the preferred method for the evaluation of diaphragm function in the Intensive Care Unit (ICU) setting, namely through the diaphragm thickening fraction (DTF). However, its potential role in the decision-making process of mechanical ventilation weaning is yet to be established. We aimed to assess the incidence of early DD and its role as a predictor of prolonged IMV.</p><p><strong>Material and methods: </strong>We conducted a prospective, non-interventional study in a university hospital ICU. Non-consecutive adult patients subject to at least 48h of IMV were enrolled. Exclusion criteria was a prior period of IMV in the past three months. DUS was performed at 48h of IMV.
