One study comparing CT arthrography and MR arthrography for talar cartilaginous lesions found an accuracy between 76% to 88% using MR arthrography compared to 90% to 92% for CT arthrography, suggesting that CT arthrography may be more reliable [6]. MR Arthrography The introduction of contrast into the ankle joint prior to MRI will outline a cartilage surface defect, assisting in lesion detection and assessment for instability. One study comparing CT arthrography and MR arthrography for talar cartilaginous lesions found an accuracy between 76% to 88% using MR arthrography compared to 90% to 92% for CT arthrography, suggesting that CT arthrography may be more reliable [6]. CT In one multimodality study, CT (noncontrast, multidetector with multiplanar reformatted images) performed similarly to arthroscopy for the evaluation of osteochondral abnormalities of the ankle [5]. However, CT was more specific (99%) but less sensitive then MRI [5]. US US is not routinely used for the evaluation of osteochondral lesions in the ankle. Radiography Stress views are not routinely used for the evaluation of osteochondral lesions in the ankle. Arthrography Arthrography is not routinely used for the evaluation of osteochondral lesions in the ankle. Variant 4: Chronic ankle pain. Ankle radiographs normal or nonspecific, suspected tendon abnormality. Next study. Possible tendon abnormalities include tenosynovitis, tendinopathy, tendon tear (partial or complete), and tendon subluxation or dislocation. Both MRI and US can effectively demonstrate ankle tendon abnormalities, although US results are more dependent on operator skill and expertise [10,35]. For the assessment, it is assumed the procedure is performed and interpreted by an expert. Chronic Ankle Pain US US can be used to evaluate for soft-tissue abnormalities, including tendon and ligament tears.
