images are the fusion of two technologies. The highly sensitive
PET Scan detects the metabolic signal of actively growing
cancer cells in the body and the CT Scan provided a detailed
picture of the internal anatomy that reveals the location,
size and shape of abnormal cancerous growth.
Alone, each imaging test
has particular benefits and limitations but when the results
of PET and CT scans are “fused” together, the
combined image provideds complete information on cancer
location and metabolism.
