Journal ArticleDOI
Nuclear Myocardial Perfusion Imaging with a Cadmium-Zinc-Telluride Detector Technique: Optimized Protocol for Scan Time Reduction
Bernhard A. Herzog,Ronny R. Buechel,Ruth Katz,Michael Brueckner,Lars Husmann,Irene A. Burger,Aju P. Pazhenkottil,Ines Valenta,Oliver Gaemperli,Valerie Treyer,Philipp A. Kaufmann +10 more
TL;DR: The minimal scan time for a CZT solid-state detector system is established, which allows 1-d stress/rest MPI with a substantially reduced acquisition time resulting in excellent agreement with regard to uptake and clinical findings, compared with MPI from a standard dual-head SPECT γ-camera.
Journal ArticleDOI
Ultrafast nuclear myocardial perfusion imaging on a new gamma camera with semiconductor detector technique: first clinical validation
Ronny R. Buechel,Bernhard A. Herzog,Lars Husmann,Irene A. Burger,Aju P. Pazhenkottil,Valerie Treyer,Ines Valenta,Patrick von Schulthess,Rene Nkoulou,Christophe A. Wyss,Philipp A. Kaufmann +10 more
TL;DR: The novel CZT camera allows a more than fivefold reduction in scan time and provides clinical information equivalent to conventional standard SPECT MPI.
Journal ArticleDOI
Diagnostic Value of 13N-Ammonia Myocardial Perfusion PET: Added Value of Myocardial Flow Reserve
Michael Fiechter,Jelena R. Ghadri,Catherine Gebhard,Tobias A. Fuchs,Aju P. Pazhenkottil,Rene Nkoulou,Bernhard A. Herzog,Christophe A. Wyss,Oliver Gaemperli,Philipp A. Kaufmann +9 more
TL;DR: The quantification of MFR in 13N-ammonia PET/CT MPI provides a substantial added diagnostic value for detection of CAD, particularly in patients with normal MPI results, which helps to unmask clinically significant CAD.
Journal ArticleDOI
Incremental prognostic value of multi-slice computed tomography coronary angiography over coronary artery calcium scoring in patients with suspected coronary artery disease
Jacob M. van Werkhoven,Joanne D. Schuijf,Oliver Gaemperli,J. Wouter Jukema,Lucia J.M. Kroft,Eric Boersma,Aju P. Pazhenkottil,Ines Valenta,Gabija Pundziute,Albert de Roos,Ernst E. van der Wall,Philipp A. Kaufmann,Jeroen J. Bax +12 more
TL;DR: MSCTA provides additional information to CS regarding stenosis severity and plaque composition and this additional information was shown to translate into incremental prognostic value over CS.
Journal ArticleDOI
Prognostic value of cardiac hybrid imaging integrating single-photon emission computed tomography with coronary computed tomography angiography
Aju P. Pazhenkottil,Rene Nkoulou,Jelena-Rima Ghadri,Bernhard A. Herzog,Ronny R. Buechel,Silke M. Küest,Mathias Wolfrum,Michael Fiechter,Lars Husmann,Oliver Gaemperli,Philipp A. Kaufmann +10 more
TL;DR: Cardiac hybrid imaging allows risk stratification in patients with known or suspected CAD and a matched defect on hybrid image is a strong predictor of MACE.
