ADVANCEMENT OF PET/CT SCAN IN DETECTING EARLY STAGE OF CANCER

Ahmad S.* and Diwakar S.

ABSTRACT

Cancer is a disease caused when cells divide uncontrollably. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. A PET-CT scan combines a CT scan and a PET scan. It gives detailed information about your cancer. You usually have a PET-CT scan in the radiology department as an outpatient. A radiographer operates the scanner. A CECT is a diagnostic procedure in which a contrast material is injected and rotating beams of X-rays are used. This test is usually done to determine the cause of symptoms like cough, shortness of breath, chest pain or to detect the presence of any tumors, injury to the internal organs. The aim of the work is to evaluate the accuracy of PET/CT vs CECT in the assessment of response to therapy in cancer patients, assessment of both early and late therapeutic response and to explore the diagnostic value of the cross-modality fusion images provided by positron emission tomography/computed tomography (PET/CT) and contrast-enhanced CT (CECT).
