Objective:
With major efforts being made to reduce radiation exposure in CT, one area of practice that requires additional improvement is limiting the number of acquisitions for body CT imaging. This review article defines best MDCT practice in terms of tailored abdominal CT protocols, designed to maximize lesion detection while limiting radiation exposure.
Conclusions:
The literature defines optimal acquisitions for a range of abdominal CT indications, with precontrast and delayed acquisitions being least commonly indicated.

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...
Imaging Studies for Cardiovascular System III: X-Ray
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...
