Figure 9b. High-resolution FEMR imaging of cartilage in the knee. Parameters for all images were 512 x 256, 16-cm field of view, and 2-mm-thick sections. (a) Sagittal T2-weighted fast SE image obtained with interleaving (imaging time, 5:30 [minutes:seconds]). (b) Sagittal 3D spoiled GRE image obtained with fat suppression (imaging time, 8:56). (c) Sagittal FEMR water image (imaging time, 2:43). (d) Sagittal FEMR lipid image. The cartilage signal on the spoiled GRE image (b) and FEMR images (c, d) is nearly identical despite the much longer imaging time for spoiled GRE imaging (8:56 vs 2:43). The cartilage signal with fast SE imaging is much lower than with FEMR or spoiled GRE imaging.
