Abstract :

Objectives: 1. To describe risks related to the use of CT 2. To recognize the metrics used to describe CT dose 3. To discuss CT dose reduction technologies The growing use of imaging procedures, particularly multidetector CT, has raised concerns about exposure to low-dose ionizing radiation in the general population and particularly in children. CT is an important source of exposure to ionizing radiation and can result in high cumulative effective doses. This has important implications for the health of the general population. Given the rapid evolution in multidetector CT technology and its complexity, dose reduction efforts require knowledge of interactions between CT scanning parameters and their impact on radiation dose and image quality in CT examinations. Advances in technology continually change the design and capabilities of CT scanners and the radiation output. Because of the dramatic rise in CT use, it is imperative that scanning techniques be optimized. Optimization in the context of the performance of CT requires that the scan be of diagnostic quality for the clinical task at hand, yet be performed at a radiation dose that addresses radiation risk to the patient and to the public. This presentation describes the primary factors affecting dose in CT and effects of modifying these primary scanning factors such as tube current, tube potential, pitch and dose reduction to sensitive tissues (e.g., breast) in CT.
