MRI in fibrous dysplasia (FD). a, b MRI typically shows sharply demarcated lesions with intermediate to low signal intensity on T1-weighted images (WI) and intermediate to high on T2-WI (red arrow). c Some FD lesions may also contain small cystic areas, which make the T2 signal bright (green arrow). d FD lesions usually show some degree of enhancement after contrast administration (blue arrow)
