Dangers of Radiation from repeated Computed Tomography Angiography Scans

Introduction

Medical imaging studies such as X-rays and computed tomography (CT) scans and radiation therapy account for the majority of radiation from man-made sources. Computed Tomography Angiography (CAT), also called CT scans, is a research method that combines the technology of combined CT and conventional angiography, which allows obtaining detailed images of blood vessels throughout the body.
