OBJECTIVES: To evaluate magnetic resonance imaging (MRI) at 3 T in the diagnosis and characterization of lesions of the finger flexor A2 pulley in patients with clinically suspected A2 pulley lesions. MATERIALS AND METHODS: Eight consecutive patients with clinically suspected lesions of the A2 pulley were included in this retrospective study. 3 T MRI was performed with T1-weighted, T2-weighted fat suppressed, and T1-weighted fat suppressed contrast enhanced sequences. The A2 pulley of all the fingers visible on the images were analyzed and pulley lesions characterized. RESULTS: All asymptomatic pulleys were normal at MRI. In the 8 symptomatic fingers 7 pulleys were abnormal at MRI. With the clinical examination as gold standard, sensitivity, specificity, positive predictive value, and negative predictive value of MRI were 87.5%, 100%, 100%, and 95.2% respectively. Characterization of the different pulley lesion was possible. CONCLUSION: MRI at 3 T allows reliable direct visualization and characterization of traumatic A2 pulley lesions.
