While the added value of dynamic MRI over conventional
static imaging has already been demonstrated in several
studies, dynamic imaging of soft tissues in the knee
such as ligaments and tendons has been investigated less
extensively, mostly due to the technical and practical
challenge of dynamic fat suppressed imaging during
movement of the knee joint. We present here a fast and
robust technique for fat suppression to be used in real
time imaging of the flexion/extension of the knee. Fat
suppression allowed segmentation and evaluation of the
posterior cruciate ligament pattern of elongation during
flexion/extension.
