Examples of MR signal intensities of lesions compared with those of the contralateral side. A 39-year-old male presented at a local clinic with pain and swelling on the right side of the mandible. Root canal treatment was performed on the right lower first molar, but the swelling did not improve. He also developed abnormal sensation of the mental nerve and was referred to our hospital. (A) T1-weighted image showing low signal intensity compared with the healthy side (ellipse). (B) T2-weighted fat-suppressed image showing high signal intensity compared with the healthy side (ellipse). An 86-year-old female presented at a local clinic with swelling in the left lower molar region of the mandible. She was treated with alendronate for osteoporosis and was referred to our clinic. (C) T2-weighted fat-suppressed image showing low signal intensity compared with the healthy side (ellipse).
