Magnetic Resonance Imaging

Abstract

Magnetic resonance imaging (MRI) is the imaging modality of choice for comprehensive evaluation of internal derangement of the knee. MRI of the knee utilizes a combination of pulse sequences that are sensitive and specific for detecting pathology in the various tissues such as menisci, ligaments, tendons, muscles, articular cartilage, synovium, and bones in the shortest possible time. This chapter aims to provide an overview of MRI systems and basic concepts of MRI such as signal-to-noise ratio and spatial resolution, as well as various pulse sequences, including fat-suppression techniques. Routine and supplementary protocols of knee MRI, recent advances, and common MRI artifacts and how to correct them are also addressed.
