From: Diagnostic accuracy of 18F–FDG PET/CT and MR imaging in patients with adenoid cystic carcinoma
No tumour recurrence: PET/CT imaging was false-positive and MRI true-negative. Patient after resection of an ACC in the right parotid gland and mandibula. A contralateral false-positive finding is seen on the PET (b) and fused PET/CT image (a) with a focally increased FDG-uptake (SUVmax 5.4; arrow), but there was no pathological finding on the contrast-enhanced T1-weighted MR image (c)
