From: Detection of distant metastases and distant second primary cancers in head and neck squamous cell carcinoma: comparison of [18F]FDG PET/MRI and [18F]FDG PET/CT

Lung metastases correctly diagnosed on PET/MRI (A, B) and PET/CT (C, D) in a 60-year-old female with nodal recurrence after radiochemotherapy for oropharyngeal HPV-negative SCC. The right upper lobe metastasis (arrows) shows a combination of high focal FDG uptake (SUVmax on PET/MRI = 7.7 and SUVmax on PET/CT = 9.3) and an excavated aspect on the contrast-enhanced fat-saturated MR image and on the corresponding CT image. The left upper lobe metastasis (dashed arrows) displays minor focal [18F]FDG uptake (SUVmax on PET/MRI = 1.7 and SUVmax on PET/CT = 2.1) and clustered nodules on the corresponding morphologic MRI/CT images. Both lesions were rated with a score of 5 on PET/MRI and PET/CT
