Sagittal fat\u2010suppressed three\u2010dimensional gradient\u2010echo (3D GRE) images, obtained with the phase\u2010contrast method at 0.23T, and fat\u2010suppressed three\u2010dimensional spoiled gradient recalled echo (3D SPGR) images, obtained with a chemical shift selective method at 1.5T, were evaluated. Diagnostic performance was analyzed. The conspicuity of the lesions, the amount of artifacts, and the uniformity of fat suppression were evaluated. The contrast\u2010to\u2010noise (CNR) values of cartilage\u2010to\u2010bone marrow, and cartilage\u2010to\u2010infrapatellar fat were calculated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>At 0.23T, sensitivity and specificity were 80% and 95% for partial cartilage lesions (grade 2), and 91% and 100% for full\u2010thickness lesions (grade 3). At 1.5T, sensitivity and specificity were 85% and 95% for grade 2 lesions, and 96% and 97% for grade 3 lesions. No significant difference was detected in the conspicuity of lesions. The uniformity of fat suppression was more constant with 3D SPGR images compared to 3D GRE images. More susceptibility artifacts, derived from the procedure of creating lesions, were detected at 1.5T.
