ABSTRACT

This is an overview of the ``cine magnetic resonance (MR) imaging'' system and rapid (ultra-fast) MR imaging of the knee for evaluation of injury of the cruciate ligament including its function during flexion and extension. Cine MR imaging using a gating system and cine acquisition delineates alterations of the signal and shape of the cruciate ligaments and menisci. Rapid (ultra-fast) MR images with a single acquisition time of a half second or less using a mobile knee brace and a flexible surface coil has enabled rapid acquisition of moving knee motion in multi-image frames. Visualization of the moving normal and torn anterior cruciate ligaments indicates that kinematic MR imaging of the moving knee is advantageous in evaluating the continuity and tension in the cruciate ligaments.
