Diagnostic performance of MR imaging of the knee is different according to lesion type and is influenced by various study design characteristics. Higher magnetic field strength modestly improves diagnostic performance, but a significant effect was demonstrated only for anterior cruciate ligament tears.

In patients with a pretreatment ABI measurement at rest of more than 0.90, classifying procedures using a criterion based on improvement in ABI measurements with more than 0.10 is inaccurate and underestimates the actual success rate at 12 months after percutaneous intervention. Furthermore, combining subjective improvement in symptoms and improvement in ABI measurements does not yield more information than reporting these outcome measures separately. Therefore, we suggest that improvement in symptoms and improvement in ABI measurements should be reported separately to indicate the 12-month success rate of percutaneous interventions for peripheral arterial disease.
