A 45-year old woman with diagnosis of primary breast cancer.
No distant metastases were detected in the CT scan (a). The subsequently performed 18F-FDG PET/MRI shows a bone metastasis in the left iliac bone with contrast enhancement on T1w fs VIBE (c) and pathological FDG uptake on PET (d) and fused 18F-FDG PET/MRI (b).

A 48-year old woman with diagnosis of primary breast cancer.
Morphologically unsuspicious right axillary lymph node rated as not malignant in the CT scan (a). The 18F-FDG PET/MRI shows a slight FDG uptake (b-d), indicating malignancy. Histopathology proved a tumor infestation.
Fig 4.
A 72-year old woman with diagnosis of primary breast cancer and lymph node metastases.
The reading radiologist did not detect the morphologically inconspicuous left clavicular lymph node in CT scan (a). In 18F-FDG PET/MRI a clear FDG uptake is visible (b-d). Histopathology confirmed malignancy.
