Figure 7

Magnetic resonance image of the left elbow, 3 years 5 months after the first visit to our department. (a) T1-weighted image (T1WI); (b) fat-suppressed T2-weighted image (T2WI-Fs); and (c) gadolinium-enhanced short T1 inversion recovery image (Gd-SPIR). The high-intensity area appeared from the peripheral cavity and internal low-intensity area became slightly brighter in T1WI. The peripheral high-intensity area was considered to demonstrate replaced bone marrow fat. The high-intensity area is noted in T2WI-Fs, but the size and signal strength decreased. In Gd-SPIR, the low-intensity area became slightly brighter, and the peripherally enhanced area seemed to be weaker (arrow).
