The usefulness of an 18F-FDG-PET/MR examination in a patient with rectal and breast cancer. A case report

Recently, we have gained access to innovative radiological and metabolic examination methods. One of these methods is PET/MRI with fluorodeoxyglucose (18F-FDG) tracer. Performing this innovative examination in a 69-year-old woman with diagnosed rectal cancer brought additional benefits. The use of PET/MRI resulted in precise clinical staging, the detection of a synchronous early-stage right breast cancer, and in the optimisation of treatment of both cancers. To date, diagnostic guidelines concerning rectal and breast cancers do not recommend the use of functional imaging for routine imaging.
