Figure 5 CT and MRI at 4-month follow-up after the first visit: (A) plain CT showing diffuse cortical bone resorption of the left condyle of the mandible; (B) MRI, with the left condyle of the mandible in part showing low-high signal intensity on a T1-weighted image; (C) MRI, with soft tissue around the left side of the ascending ramus of the mandible showing heterogeneous high-signal intensity on a fat-suppressed T2-weighted image.
