Magnetic resonance imaging of normal anatomy and injury of the peroneal tendon

To explore the MR characteristics of normal anatomy and injured peroneal tendon and the diagnostic value of MR in the peroneal tendon injuries. From February 2018 to December 2018, a total of 20 healthy volunteers (40 ankle joints) were selected, 10 males and 10 females, with an age range of 20-30 (26±3) years. Retrospective analyzed 62 patients with ankle sprain and peroneal tendon injuries confirmed by operation, 34 males and 28 females, with an age range of 14-78(41±14) years. All volunteers and patients underwent MR examination. The MRI characteristics of the normal anatomy of peroneal tendon were analyzed. The patients were classified according to the MR diagnostic criteria of injury. Then the MRI features of different types of injured peroneus longus tendon and peroneus brevis tendon were analyzed. At last, imaging findings were compared with surgical results. The peroneal tendon of 20 healthy volunteers showed oval and elliptical band-like structures on T(1)WI and PD-FS sequences, with natural alignmen
