Radiation dose reduction in CT-guided cryoablation of renal tumors

PURPOSE We aimed to evaluate the effect on the radiation dose to the patient by reducing the tube current during the placement of the ablation needles (reduced dose group) compared with the patient doses delivered when scanning at the standard fully diagnostic level (full dose group) in computed tomography (CT)-guided percutaneous cryoablation. METHODS We conducted a retrospective study of 103 patients undergoing cryoablation in a tertiary...
