Journal ArticleDOI
Coronary CT Angiography–derived Fractional Flow Reserve: Machine Learning Algorithm versus Computational Fluid Dynamics Modeling
Christian Tesche,Carlo N. De Cecco,Stefan Baumann,Matthias Renker,Tindal W. McLaurin,Taylor M. Duguay,Richard R. Bayer nd,Daniel H. Steinberg,Katharine Grant,Christian Canstein,Chris Schwemmer,Max Schoebinger,Lucian Mihai Itu,Saikiran Rapaka,Puneet Sharma,U. Joseph Schoepf +15 more
TL;DR: The FFRML algorithm performs equally in detecting lesion-specific ischemia when compared with the FFRCFD approach, and both methods outperform accuracy of coronary CT angiography and QCA in the detection of flow-limiting stenosis.
Journal ArticleDOI
Single- and dual-energy CT of the abdomen: comparison of radiation dose and image quality of 2nd and 3rd generation dual-source CT.
Julian L. Wichmann,Andrew D. Hardie,U. Joseph Schoepf,Lloyd M. Felmly,Jonathan D. Perry,Akos Varga-Szemes,Stefanie Mangold,Damiano Caruso,Damiano Caruso,Christian Canstein,Christian Canstein,Thomas J. Vogl,Carlo N. De Cecco +12 more
TL;DR: With both DSCT generations, abdominal DECT can be routinely performed without radiation dose penalty compared to SECT, while third-generation DSCT shows improved dose efficiency.
Journal ArticleDOI
Image quality and radiation dose of low tube voltage 3rd generation dual-source coronary CT angiography in obese patients: a phantom study
Felix G. Meinel,Felix G. Meinel,Christian Canstein,U. Joseph Schoepf,Martin Sedlmaier,Bernhard Schmidt,Brett S. Harris,Thomas Flohr,Carlo N. De Cecco,Carlo N. De Cecco +9 more
TL;DR: Third-generation DSCT enables one to perform coronary CTA at 70–80 kV in obese patients without compromising CNR and thus reduces radiation dose by 49–68 %, and low tube potential CT angiography is currently not suitable for obese patients.
Journal ArticleDOI
Dual-Energy Computed Tomography Angiography of the Lower Extremity Runoff: Impact of Noise-Optimized Virtual Monochromatic Imaging on Image Quality and Diagnostic Accuracy.
Julian L. Wichmann,Matthew R. Gillott,Carlo N. De Cecco,Stefanie Mangold,Akos Varga-Szemes,Ricardo Yamada,Katharina Otani,Christian Canstein,Stephen R. Fuller,Thomas J. Vogl,Thomas M. Todoran,U. Joseph Schoepf +11 more
TL;DR: Image reconstruction using low-kiloelectron volt VMI+ improves image quality and diagnostic accuracy compared with traditional VMI technique and standard linear blending for evaluation of the lower extremity runoff using dual-energy CTA.
Journal ArticleDOI
Virtual unenhanced imaging of the liver with third-generation dual-source dual-energy CT and advanced modeled iterative reconstruction
Carlo N. De Cecco,Giuseppe Muscogiuri,Giuseppe Muscogiuri,U. Joseph Schoepf,Damiano Caruso,Damiano Caruso,Julian L. Wichmann,Paola M. Cannaò,Paola M. Cannaò,Christian Canstein,Stephen R. Fuller,Lauren Snider,Akos Varga-Szemes,Andrew D. Hardie +13 more
TL;DR: Third-generation DSCT VU images of the liver provide diagnostic image quality and improve small liver lesion detection; however calcified liver lesions can be missed due to complete subtraction.
