2. Fig. 1
Direct comparison between different sequences used in the current study. (A) Sagittal DESS image shows cystic portion of femoral and tibial bone marrow lesions (BML) and some ill-defined parts of BML in both, femur (arrows) and tibia (arrowheads). (B) Sagittal SPACE, a 3D T2-weighted FSE fat suppressed fast spin echo sequence, superiorly depicts ill-defined BMLs that are visualized in much larger fashion in femur (arrows) and tibia (arrowheads) compared to DESS. (C) Sagittal SPACE image in another patient shows a BML in the anterior medial tibia (arrows). No bone marrow changes are seen in the femur. (D) Corresponding sagittal DESS shows tibial BML to a much smaller extent compared to SPACE (long arrow). High intensity signal changes in the medial femur represent artifacts as a result of popliteal vessel pulsation and must not be mistaken as bone marrow lesions (small arrowheads). (E) Corresponding coronal T1 weighted image shows tibial BML as a circumscribed hypointensity (large arrowhead). No signal alterations are seen in the femur confirming that signal changes seen in D represent an artifact.
