PET/CT and Colorectal Cancer Diagnosis and treatment
Although not particularly used for diagnosing colorectal cancer PET/CT is an
effective procedure used in planning treatments for this form of cancer. The
CT scan will show the structure of the organs and tissues in the abdomen and
the PET scans from the PET/CT scanner will be able to detect whether or not
the cancer has spread into other areas and where the cancer is alive and thriving.
PET imaging is able to detect cancerous cells, as it is a metabolic imaging
tool. With PET scans, the chemical function of the colon and rectum or other
targeted organs or tissues are examined. PET images are able to visualize biochemical
changes caused by disease.
Combining the anatomical location from the CT scan with the biochemical changes
of the PET scan can provide an excellent tool in detecting colorectal cancer.
