Purpose:
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.
Materials And 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.
Conclusion:
Dynamic MRI of joints with TrueFISP is feasible and can provide information supplemental to static joint examinations.
