PET Scan - Colon Cancer
PET Scan for Colon Cancer - Overview & Techniques
Archer Radiology offers a PET scan for colon cancer.
PET scanning is the most common form of molecular imaging used in diagnosing and guiding the treatment of colorectal cancer. It is often employed in conjunction with computed tomography (CT) scanning. In one out of three cases, the combination of PET and CT scans leads to changes in a patient's treatment.
After treatment, the disease often recurs in the same place. A PET/CT scan can analyze any suspicious masses and ascertain whether they are cancerous tumors or mere scar tissue. The cancer may also spread to the liver, requiring surgery. In this case PET/CT scanning will specify to which sites the disease has spread, eliminating unnecessary preventive surgery and increasing the patient survival rate.
A colon cancer patient may require a PET/CT scan intermittently throughout the progress of the disease, for purposes of diagnosis, treatment, and the prevention of recurrence.
