Abstract

Image quality is proportional to radiation dose. Improvements in image quality come at a cost of increased radiation dose. CT scanners are more robust today than even 5 years ago. X-ray tubes are capable of producing high levels of almost continuous radiation for rapid CT volume acquisitions and angiographic studies. All parameters of modern CT scanners provide rapid subsecond, large-volume CT acquisitions. How high we go needs to be tempered by how high we should go regarding radiation dose from CT examinations. Radiologists, referring physicians, medical physicists, CT technologists, CT equipment manufacturers, and regulators need to evaluate the appropriateness of radiation dose for different CT studies.
