Abstract:
With its superior tissue contrast and sensitivity to tissue composition, magnetic resonance imaging MRI plays a leading diagnostic role in assessing the musculoskeletal MSK system and is well established for most questions at clinically used field strengths up to 3 T.1 Although low-field MR imaging up to but not including 1.5 T may be used efficiently in daily clinical practice,2,3 most musculoskeletal MR examinations are performed at magnetic field strengths of 1.5 or 3 T.4 While at 1.5 T most musculoskeletal tissues cartilage, muscle, tendon, ligaments, bones, etc. exhibit sufficient signal-to-noise ratio SNR, which is limited by the small field-of-view FOV that is usually utilized, 3 T MRI has recently demonstrated improved imaging quality and speed and provided preliminary evidence for concomitant improvement in diagnostic accuracy.
