Magnetic Resonance Imaging of the Knee 2001
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.
