A protocol for scoping reviews on the role of whole-body and dedicated body-part magnetic resonance imaging for assessment of adult and juvenile idiopathic inflammatory myopathies.

Currently, standardized magnetic resonance imaging (MRI) scoring systems and protocols for assessment of idiopathic inflammatory myopathies (IIMs) in children and adults are lacking. Therefore, we will perform a scoping review of the literature to collate and evaluate the existing semi-quantitative and quantitative MRI scoring systems and protocols for the assessment and monitoring of skeletal muscle involvement in patients with IIMs. The aim is to compile evidence-based information that will facilitate the future development of a universal standardized MRI scoring system for both research and clinical applications in IIM. A systematic search of electronic databases (PubMed, EMBASE, and Cochrane) will be undertaken to identify relevant articles published between January 2000 and October 2023. Data will be synthesized narratively. This scoping review seeks to comprehensively summarize and evaluate the evidence on the scanning protocols and scoring systems used in the assessment of diagnosis, disease activity, and damage using skeletal muscle MRI in IIMs. The results will allow the development of consensus recommendations for clinical practice and enable the standardization of research methods for the MRI assessment of skeletal muscle changes in patients with IIMs.

Imaging of solitary and multiple osteochondromas: From head to toe - A review.

Osteochondromas account for 20%-50% of all benign bone lesions. These tumors may present as solitary non-hereditary lesions, which are the most common presentation, or as multiple tumors associated with hereditary conditions. Plain radiography is the imaging method of choice and demonstrates the typical cortical and medullary continuity of the tumor with the underlying bone. Magnetic resonance imaging is often performed to evaluate cartilage cap thickness, which correlates with malignant transformation. Other local complications include compression of adjacent neurovascular bundles, muscles, and tendons, bursitis, tendon tears, stalk fracture, and angular or rotational long bone deformities. Although the imaging features of osteochondromas are largely known, only a few papers in the literature have focused on their main complications and image-based follow-up. This paper aimed to illustrate the main complications of osteochondromas, suggest an image-based algorithm for management and follow-up and discuss differential diagnosis.
