Design outcomes

Primary

Measure	Time frame
The main study parameters are normal-dose CT and low-dose CT. The main endpoints are the subjective and objective image quality at different dose reduction levels for both standard and iterative reconstruction.	—

Secondary

Measure	Time frame
Secondary endpoints are coronary calcifications (cardiac CT), pulmonary nodule volume (chest CT) and detectability and size of urinary concrements (abdominal CT).	—
