Evaluating the effectiveness of imaging-based screening requires understanding of diagnostic performance, disease prevalence and incidence, and appropriate measures of benefits and harms. Multiple screening programs based on imaging tests have been broadly implemented, for both cancerous and noncancerous abnormalities. Breast cancer, and more recently prostate cancer and colorectal cancer screening programs have seen an increased role for imaging. In this article, we review principles underlying imaging screening programs, provide an overview of established imaging-based screening and technical considerations, and describe how cost-effectiveness principles apply to screening evaluation.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

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...

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...
