Real-time MRI of joint movement with trueFISP.
OBJECTIVE
To develop a technique for dynamic magnetic resonance imaging (MRI) of joint motion based on a combination of real-time TrueFISP (fast imaging with steady state precession) imaging with surface radiofrequency (RF) coils.


METHODS
The metacarpal, elbow, tarsal, and knee joint of five volunteers and the knees of four patients were examined with a real-time TrueFISP sequence during movement of the joints.


RESULTS
All examined joints could be assessed under dynamic conditions with high image contrast and high temporal resolution.


CONCLUSIONS
Dynamic MRI of joints with TrueFISP is feasible and can provide information supplemental to static joint examinations.
