Performance of reduced- versus conventional-dose computed tomography in detection of parenchymal lung abnormalities: a systematic review protocol

Deliberate exposure to ionizing radiation during medical investigations, such as chest CT, should be as low as reasonably practicable to reduce the risk of inducing cancer. Certain populations are at particular risk, such as those undergoing lung cancer screening and workers exposed to dust, and require multiple scans over time with high baseline risk.

Abstract:
Deliberate exposure to ionizing radiation during medical investigations, such as chest CT, should be as low as reasonably practicable to reduce the risk of inducing cancer. Certain populations are at particular risk, such as those undergoing lung cancer screening and workers exposed to dust, and require multiple scans over time with high baseline risk.
