Some anterior cruciate ligament reconstructions have metal implants, and metal scrap may remain in the surgical procedure. Metals in the conventional magnetic resonance sequence, especially in the fat suppression sequences, produce large artifacts that affect the observation of the surrounding structure. This study performed conventional sequences and MAVRIC-SL sequence scan for patients with metal implants after ACLR and analysis the images. Conclusions that the oblique sagittal MAVRIC-SL PDWI FS sequence can be used to assisting in the diagnosis of traditional oblique sagittal T2WI FS and PDWI sequence.
