Carlo Nicola De Cecco, M.D., PhD

Purpose: To compare, on an intra-individual basis, the effect of automated tube voltage selection (ATVS), integrated circuit detector and advanced iterative reconstruction on radiation dose and image quality of aortic CTA studies using 2nd and 3rd generation dual-source CT (DSCT). Read more

Cerebral CTA with Low Tube Voltage and Low Contrast Material Volume for Detection of Intracranial Aneurysms.

Carlo Nicola De Cecco, M.D., PhD

Background and Purpose: Multidetector row CTA has become the primary imaging technique for detecting intracranial aneurysms. Technical progress enables the use of cerebral CTA with lower radiation doses and contrast media. We evaluated the diagnostic accuracy of 80-kV(peak) cerebral CTA with 30 mL of contrast agent for detecting intracranial aneurysms. Read more

The purpose of this study was to assess image quality and radiation dose of lower extremity CTA with 70 kVp, high pitch acquisition and SAFIRE. Read more

Image quality and radiation dose of lower extremity CT angiography at 70 kVp on an integrated circuit detector DSCT

posted by U. Joseph Schoepf, M.D. | May 11, 2015
U. Joseph Schoepf, M.D.

To compare the image quality and radiation dose of lower extremity CTA at 70 kVp using a dual-source CT system with an integrated circuit detector to similar studies at 120 kVp. Read more

Reduced radiation dose and improved image quality at cardiovascular CT angiography by automated attenuation-based tube voltage selection: intra-individual comparison

posted by U. Joseph Schoepf, M.D. | May 1, 2015
U. Joseph Schoepf, M.D.

To evaluate the effect of automated tube voltage selection on radiation dose and image quality at cardiovascular CTA. Read more

ECG-Synchronized CT Angiography in 324 Consecutive Pediatric Patients: Spectrum of Indications and Trends in Radiation Dose

posted by Thomas Henzler, MD | Apr 13, 2015
Thomas Henzler, MD

The aim of the study is to describe the spectrum of indications for pediatric ECG-synchronized CT angiography (CTA), the main determinants of radiation exposure, and trends in radiation dose over time at a single, tertiary referral center. Read more
