Water-suppression MRI: Role in the evaluation of osseous lesions

The efficacy of chemical shift based wafer-suppression MRI in the evaluatio n of bone marrow lesions hers not been previously reported. T1-weighted ima ges without and with water suppression were compared in five patients with 16 lesions. There was a significant improvement in the contrast-to-noise ra tio (from 4.32 to 5.95, P < 0.01) and contrast ratio (from 1.71 to 5.69, P < 0.004) with water suppression. Water suppression may be useful clinically by increasing the conspicuity of bone marrow lesions. (C) Elsevier Science Inc., 2000.
