DETECTION OF MULTIFOCAL BREAST-CARCINOMA BY 2[F-18]FLUORODEOXY-D-GLUCOSE POSITRON-EMISSION-TOMOGRAPHY (FDG-PET)

The elevated rate of glycolysis in malignomas compared to normal tissu es can be visualised by positron-emission-tomography (PEI) using 2[F-1 8]fluoro-deoxy-D-Glukose (FDG). Based on the case of a 38-year old wom an with multifocal carcinoma of the right breast (pT1 c pN0 M0, G2) as a vehicle, we describe a FDG-PET procedure which is comparable to est ablished methods of nuclear medicine (e. g. bone scan) with regard to patient's burden and time consumption and could be used on a routine b asis. This technique allowed correct assessment of suspicious breast f indings and visualised multifocal growth of a tumour which was judged to be a unifocal breast cancer by conventional methods of clinical exa mination, mammography and ultrasound.
