Abstract:
Cancer staging is how clinicians describe the state of the disease, predict prognosis, help determine best treatment, and interpret outcomes. Although several staging systems are available, the most widely used is the tumor node metastasis (TNM) system developed by the American Joint Committee on Cancer. Knowledge of normal anatomy and the myriad appearances of variations in anatomy is the basis of accurate tumor staging. Cross-sectional imaging is complementary to the clinical examination for accurate staging.

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
