The progress of magnetic resonance imaging (MRI) as a clinical tool has been surprising, out-stripping the rate of development of any other imaging modalities. MRI is often used to help investigate the source of many potential knee problems and conditions. Use this guide to help understand some of the common conditions seen by MRI The Magnetic Resonance Imaging Appearance of the knee joint has proved highly successful in guiding the study of the anatomical structures of the knee joint in sagittal planes , to evaluate the fast spin echo/T1 and fast spin echo/proton density/SPIR pulse sequences in demonstrating different anatomical structures of the knee joint in sagittal planes, to compare between the two pulse sequences in anatomical structures imaging appearance of the knee joint in sagittal planes, and find out which is the best between the two pulse sequences that demonstrate the anatomical structures of the knee joint on sagittal planes.
