COMPUTED TOMOGRAPHY (CT) SCANNING: ASSISTING WITH

Course overview

Computed tomography (CT) scanning, also known as computed axial tomography (CAT) scanning, is a diagnostic imaging procedure that uses a series of two-dimensional (2-D) X-ray images to create a three-dimensional (3-D) image of the inside of the body. CT scans are performed to visualize the organs, bones, soft tissues, and vascular structures, and may be conducted with or without contrast media (e.g., iodine-based contrast media [ICM], barium sulfate), materials that when ingested or administered intravenously or rectally enhance certain views of anatomical structures. This continuing education module is designed to give the reader/learner an increased understanding of the nurse’s role in assisting with CT scanning. Readers may explore any or all of the topics. One contact hour of continuing education credit is available for those who successfully complete the post-test and evaluation form.
