Szintigraphie/Positronenemissionstomographie

Skeletal scintigraphy and fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) are established nuclear medicine modalities in the diagnosis of soft tissue tumors. Skeletal scintigraphy scans are performed for detection of osseous infiltration by the primary tumor, of bone metastases and planning of magnetic resonance imaging (MRI). The PET/CT technique has a great potential for assessing tumor grade, for accurate N and M staging, treatment monitoring and in biopsy planning. Recurrent tumors can be detected with high sensitivity, particularly if conventional imaging is impaired by metallic implants. According to current guidelines, if a malignant soft tissue tumor is suspected or proven, PET/CT and PET/MRT should be considered even in children and adolescents.
