Imaging of Osteochondral Injuries

Comparison study of intraarticular and intravenous gadolinium-enhanced magnetic resonance imaging of cartilage in a canine model

“…MR arthrography has been used to evaluate the articular cartilage of joints for more than 10 years (14)(15)(16)(17)(18)(19). Direct MR arthrography with the injection of a dilute solution of gadolinium directly into the joint (iGEMRIC) improves the visualization of cartilage, owing to the contrast between cartilage and the injected fluid (1,44).…”

Osteochondral Lesions of the Talus: Change in MRI Findings Over Time in Talar Lesions Without Operative Intervention and Implications for Staging Systems

“…9,10,17 Moreover, there may be no history of trauma (fracture or severe ankle sprain) in many patients in whom an osteochondral lesion is found incidentally during evaluation of chronic ankle pain. 8,17,19 MRI is a valuable tool in diagnosing osteochondral lesions of the talus, 5,6,7,12,13,16 and staging of the lesions. 8,11,20 MRI criteria in these systems include bone marrow edema, cysts, and signal intensity of the interface between osteochondral lesions of the talus and the underlying bone.…”

Osteochondral Lesions of the Talus: Localization and Morphologic Data from 424 Patients Using a Novel Anatomical Grid Scheme

“…2,6,12,14,16 Arthroscopy remains the standard for assessing the talar articular surface when operative intervention is indicated for patients with osteochondral lesions of the talar dome. Nonetheless, some osteochondral lesions reported on MRI are not detected during ankle arthroscopy.…”
