Colorectal Cancer PET/CT Utilization and Case Studies
PET/CT is a noninvasive test that physicians utilize to stage the body for the presence or absence of active tumor, localize the tumor, assess the tumor response to treatment and detect recurrence in treated lesions.
PET/CT Utilization for Colorectal Cancer
Detecting of tumor recurrence in patients with rising levels of serum CEA and otherwise normal radiographic studies
Determining if a radiological abnormality is a resectable recurrence, its true extent, and if it has metastasized elsewhere
Detecting intra-abdominal, hepatic or other metastases
Detecting extrahepatic metastases before a potentially curable hepatic resection
Evaluating efficacy of treatment such as chemotherapy and radiation
Evaluating response to treatment
