Advice for patients. Decreasing unnecessary radiation exposure for children.

摘要

Today there are several methods of medical diagnostic imaging. These include radiography (sometimes called x-rays), computed tomography (sometimes called CT scans), fluoroscopy, and nuclear medicine scans. In radiography, x-rays (invisible beams of ionizing radiation) pass through the body and create 2-dimensional images of many organs and bones. Radiography may be used to evaluate for a possible broken bone or pneumonia.
