Magnetic resonance imaging of the anterior cruciate ligament: current concepts

Abstract

MR imaging of the anterior cruciate ligament (ACL) can provide highly accurate information and is the most diagnostic current imaging procedure for suspected injuries to the ligament. It is safe, absent of ionizing radiation, non-invasive, and tolerated well by patients. There have been significant advances in technique and the ability to interpret images. One can expect sensitivities of 92% to 96% and specificities of 92% to 98%. This imaging test of the ACL can provide useful information in establishing the normal anatomy, diagnosing tears, and studying the reconstructed graft.
