U. Joseph Schoepf, M.D.

The purpose of this study was to determine whether ultralow-radiation-dose chest CT can be used for quantification of lung density and for emphysema detection in participants undergoing lung cancer screening. Read more

Dual energy CT: how well can pseudo-monochromatic imaging reduce metal artifacts?

posted by Michael M. Lell, M.D. | Jul 15, 2015
Michael M. Lell, M.D.

Pseudo-monochromatic imaging is able to reduce beam hardening, scatter, and metal artifacts in some cases but it cannot remove them. Read more

Technical prerequisites and imaging protocols for dynamic and dual energy myocardial perfusion imaging

The combination of CCTA morphological assessment and CTMPI functional evaluation holds promise for achieving a comprehensive assessment of coronary artery anatomy and myocardial perfusion using a single image modality. Read more

Effect of reduced x-ray tube voltage, low iodine concentration contrast medium, and sinogram-affirmed iterative reconstruction on image quality and radiation dose at coronary CT angiography: Results of the prospective multicenter REALISE trial

posted by U. Joseph Schoepf, M.D. | Jul 7, 2015
U. Joseph Schoepf, M.D.

Using low x-ray tube voltage and IR allows for decreasing the iodine load and effective radiation dose at CCTA while maintaining image quality. Read more

Imaging the Parasinus Region with a Third-Generation Dual-Source CT and the Effect of Tin Filtration on Image Quality and Radiation Dose

posted by Michael M. Lell, M.D. | Jul 1, 2015
Michael M. Lell, M.D.

CT is the imaging technique of choice in the evaluation of midface trauma or inflammatory disease. We performed a systematic evaluation of scan protocols to optimize image quality and radiation exposure. High resolution 3D imaging can be performed at a dose level comparable to conventional radiography. Read more
