There is an increasing role for interventional radiology in the treatment of recurrent and oligometastatic disease in these tumour types. This clinical radiology review is aimed primarily at non-specialist cross-sectional consultant radiologists and more junior radiology consultants/specialist trainees with a special interest in musculoskeletal oncology. The existing role of F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) and MRI for assessment of treatment response in STS and DT, including the emerging role of whole-body MRI is outlined. Response metrics including Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1), modified RECIST, Positron Emission Tomography Response Criteria in Solid Tumours (PERCIST), immune Response Evaluation Criteria in Solid Tumors, iPERCIST and non-perfused volume ratio are also discussed in context. We introduce the potential role for locoregional therapies (LRTs), including microwave, cryotherapy and therapeutic ultrasound-based treatments as adjunctive treatments for selected cases within the current UK guidelines. We discuss the potential of high intensity focused ultrasound and other LRTs to release sarcoma tumour antigens systemically with the potential to enhance anti-tumour immunity (the 'abscopal' effect). With increasing indications and availability of locoregional therapies (LRTs) and the first indications of immunotherapy for selected subtypes of STS, potential future directions in functional imaging capability for STS and DT are also discussed.</p>","PeriodicalId":10695,"journal":{"name":"Clinical radiology","volume":" ","pages":"106969"},"PeriodicalIF":2.1,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144324689","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}

Osteogenesis imperfecta (OI) is an important differential in infants presenting with unexplained fracture(s), and some argue that classic metaphyseal fractures occur accidentally in children with OI.

Radiographs and reports were reviewed by two observers. The site and type of fractures were recorded along with other radiological features of OI. Descriptive and inferential statistics were used to analyse the results.</div></div><div><h3>RESULTS</h3><div>There were 109 eligible patients (53 female) who had a total of 3,142 images (1,949 images in those less than 1 year old). There were 87 patients (79.8%) with a total of 462 long bone fractures, of which 386 (83.5%) were diaphyseal and 76 (16.5%) were at the junction of the diaphysis and metaphysis. No classic metaphyseal fractures were identified.</div></div><div><h3>CONCLUSION</h3><div>The absence of classic metaphyseal fractures in this large cohort suggests that OI is rarely, or not at all, associated with such fractures. However, metadiaphyseal fractures, reflecting bone fragility, are common; distinction should be made between ‘classic metaphyseal’ and ‘metadiaphyseal’ fractures to facilitate clinical decision-making. The unspecified term ‘metaphyseal fracture’ should be avoided. Children less than 2 years old with OI and classic metaphyseal fractures should be thoroughly investigated to exclude inflicted injury.</div></div>","PeriodicalId":10695,"journal":{"name":"Clinical radiology","volume":"87 ","pages":"Article 106964"},"PeriodicalIF":2.1,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144253815","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}
