Although CT and MRI of Antiresorptive agent-related osteonecrosis of the jaw(ARONJ)/medication-related osteonecrosis of the jaw(MRONJ)show nonspecific findings as seen in active osteomyelitis, there are some characteristics as follows;unilateral maxillary sinusitis adjacent to ipsilateral maxillary ARONJ/MRONJ on CT and MRI, DRONJ presenting larger sequestrum and periosteal reaction more frequently than BRONJ on CT, BRONJ resulting from intravenous administration of the drug presenting larger and more frequent buccolingual cortical bone perforations than BRONJ from oral administration on CT, and better diagnostic accuracy of extent of perilesional soft tissue inflammation on MR imaging than CT.
