Breast Displacement and CT Radiation Dose

Completed · Not applicable

Conditions studied: Computed Tomography, Radiation Dosage

In brief

The primary hypothesis of this study is that breast displacement out of the direct plane of imaging during computed tomography (CT) of the abdomen will reduce effective radiation dose to the female breast. Secondary hypotheses are that image noise and artifacts will also be decreased.
