Cranial CT with adaptive statistical iterative reconstruction: improved image quality with concomitant radiation dose reduction.


BACKGROUND AND PURPOSE To safeguard patient health, there is great interest in CT radiation-dose reduction. The purpose of this study was to evaluate the impact of an iterative-reconstruction algorithm, ASIR, on image-quality measures in reduced-dose head CT scans for adult patients. MATERIALS AND METHODS Using a 64-section scanner, we analyzed 100… (More)
