Integrated imaging combining PET metabolic data with CT anatomical information
Expansion
Combined PET and CT
Purpose
Gold standard for oncology staging (tumour, node, metastasis), surveillance, and therapy response assessment
Clinical Context
PET-CT improves specificity by fusing metabolic (PET) with anatomical (CT) information. Reduces false positives from benign uptake. Radiation dose approximately 10 to 15 millisieverts.
