Dual Energy CT of peripheral arteries and Dual Energy CT Angiography of Peripheral Arterial Occlusive Disease

posted by Thorsten R. C. Johnson, M.D. | Feb 2, 2009
Thorsten R. C. Johnson, M.D.

Scott Schonhover, technologist, USA, has sent the following question: DE Runoffs: Is anyone doing these either as research or in a clinical setting? If so is there a protocol for scanning and/or injection? I undertand that certain body habitus patients would exceed scan FOV’s. One of our doc’s is contemplating a research study on … Read more

Low kilovoltage cardiac dual-source CT: attenuation, noise, and radiation dose

posted by Sebastian Leschka, M.D. | Nov 16, 2008
Sebastian Leschka, M.D.

The purpose of this study was to investigate the effect of low kilovoltage dual-source computed tomography coronary angiography (CTCA) on qualitative and quantitative image quality parameters and radiation dose. Dual-source CTCA with retrospective ECG gating was performed in 80 consecutive … Read more
