Pointers for optimizing radiation dose in chest CT protocols.

摘要

Chest CT represents the third most commonly performed CT examination [1]. Use of the appropriate radiation dose for chest CT is especially important because of direct radiation exposure of breasts, lungs, and other organs, such as the thyroid, which represent some of the most radiosensitive organs in the human body. In this article, we review practical strategies for reducing radiation dose associated with chest CT examinations.
