2001- Magnetic Resonance Imaging of the Knee. – The Journal of Bone and Joint Surgery, Incorporated
Magnetic resonance imaging is an excellent modality for visualizing pathological processes of the knee joint. It allows high-resolution imaging not only of the osseous structures of the knee but, more importantly, also of the soft-tissue structures, including the menisci and liga- mentous structures, in multiple orthogonal planes. There are multiple imaging techniques an d pulse sequences for magnetic resonance imaging of the knee. The purposes of this report are to update orthopaedic surgeons on the applications of and in- dications for magnetic resonanc e imaging of the knee, define the normal anatomy of the knee as seen on magnetic resonance imaging, and illustrate the spec trum of disease detectable by magnetic resonance imaging
Educational Objectives After reviewing this article, the reader should (1) have a basic understanding of the ph ysics, pulse sequences, and terminology of magnetic resonance imaging; (2) be able to sys- tematically evaluate a complete magnetic resonance imaging examination of the knee and know the features of normal knee anatomy; (3) be able to identify various tissue types on T1-weighted, T2-weighted, and fat-suppressed T2-weighted images; (4) be able to develop a differential diagnosis when a patient has knee pain; and (5) be able to review a series of cases and decide whether magnetic resonance imaging is indicated and be able to provide a diagnosis after evaluating the images.
