BACKGROUND AND PURPOSE: Increasing use of CT for evaluating neurologic disease
may expose patients to considerable levels of ionizing radiation. We compared the image …

BACKGROUND AND PURPOSE: CT is a frequent examination that is performed using
ionizing radiation. We sought to assess image-quality changes on CT scans of the head …

This article reviews a number of portable CT scanners for clinical imaging. These include the
CereTom, Tomoscan, xCAT ENT, and OTOscan. The Tomoscan scanner consists of a gantry …

PURPOSE: To assess the quality of brain computed tomographic (CT) studies obtained with
a four-channel multi–detector row CT scanner compared with those obtained with a single …

OBJECTIVE. The purpose of our study was to evaluate the dose and image quality
performance of a dedicated cone-beam CT (CBCT) scanner in comparison with an MDCT …

Purpose To evaluate and compare image quality and radiation dose of sequential computed
tomography (CT) examinations of the brain and spiral CT examinations of the brain imaged …

AIM: To prospectively compare helical and traditional sequential acquisition of computed
tomography (CT) images of the head with respect to lens dose, thyroid dose, and image …

The purpose of this study was to analyze the effect of various tube current settings (mAs) and
optimize the image quality and dose for adult cranial CT protocol. Sixty adult patients who …

BACKGROUND AND PURPOSE: The advancement of multidetector CT technology has
resulted in improved image quality as well as an increase in ionizing radiation dose to …

The purpose of our study was to investigate the effect of iterative reconstruction (IR) as a
dose reduction system on the image quality (IQ) of the adult head computed tomography …
