ObjectiveTo assess the cancer risk in children and adolescents following

exposure to low dose ionising radiation from diagnostic computedtomography (CT) scans.

Introduction

The term “computed tomography”, or CT, refers to a computerized x-

ray imaging procedure in which a narrow beam of x-rays is aimed at apatient and quickly rotated around the body, producing signals thatare processed by the machine’s computer to generate cross-sectional

images—or “slices”—of the body. These slices are calledtomographic images and contain more detailed information thanconventional x-rays.

Slide5

Introduction

*Computed tomography --also known as computed axial tomography,a CT scan, or a CAT scan -- is a tool doctors use to diagnose many

types of health problems. Special X-ray equipment creates images ofthe structures inside your body. * These pictures allow doctors to get a

look at your internal organs, tissues, and blood vessels.A CT scan exposes your body to some radiation.

Slide6

Radiation doses from CT scans

 A CT scan uses what’s called “ionizing” radiation. It’s powerful

enough to pass through your body to create clear images on acomputer. This type of radiation could raise your chances of cancer atsome point in the future.

Slide7

Ct scan lead to cancer

Some people worry about getting this test because radiation is known as a possible causeof cancer. Know that the chances of getting

cancer from a CT scan are very low. And formany people, the test is worth the small risk ofradiation exposure. It can help doctors spot

dangerous health problems and check thattreatment works.Your doctor will make sure that the benefitsyou’d get from the scan outweigh the

drawbacks before they recommend it foryou.
