Decreasing Patient Radiation Dose from CT Imaging: Achieving Sub-mSv Studies (U01)

archived

Computed tomography (CT)-based imaging procedures have led to significant improvements in the diagnosis and treatment of numerous medical conditions and diseases. However, CT scanners can expose patients to cumulative radiation doses which may elevate individuals lifetime risk of developing cancer or other health problems. Physicians minimize this potential risk by carefully considering the risk-to-benefit-ratio of a CT scan as well as alternative diagnostic approaches. Research focusing on ways to reduce the radiation dose from CT scanning, while still providing the superior image quality, could shift this ratio further to the benefit side. The purpose of this FOA is to encourage research leading to reduction of patient radiation exposure from a CT scan. The goal of this FOA is that research outcomes will result in routine CT scan patient radiation exposures of less than one mSv.
