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
Absolute Myocardial Blood Flow and Flow Reserve Assessed by Gated SPECT with Cadmium-Zinc-Telluride Detectors Using 99mTc-Tetrofosmin: Head to Head Comparison with 13N-Ammonia PET.
Rene Nkoulou,Tobias A. Fuchs,Aju P. Pazhenkottil,Silke M. Küest,Jelena R. Ghadri,Julia Stehli,Michael Fiechter,Bernhard A. Herzog,Oliver Gaemperli,Ronny R. Buechel,Philipp A. Kaufmann +10 more
TL;DR: The estimation of absolute MBF index values by CZT SPECT MPI with 99mTc-tetrofosmin is technically feasible, although hyperemic values are significantly lower than from PET with 13N-ammonia, resulting in a substantial underestimation of MFR.
Journal ArticleDOI
Validation of deep-learning image reconstruction for coronary computed tomography angiography: Impact on noise, image quality and diagnostic accuracy.
Dominik C. Benz,Georgios Benetos,Georgios Rampidis,Elia von Felten,Adam Bakula,Aleksandra Sustar,Ken Kudura,Michael Messerli,Tobias A. Fuchs,Catherine Gebhard,Aju P. Pazhenkottil,Philipp A. Kaufmann,Ronny R. Buechel +12 more
TL;DR: DLIR significantly reduces noise in CCTA compared to ASiR-V, while yielding superior image quality at equal diagnostic accuracy, with DLIR-H yielding the highest image quality.
Journal ArticleDOI
Coronary computed tomography angiography with model-based iterative reconstruction using a radiation exposure similar to chest X-ray examination
Tobias A. Fuchs,Julia Stehli,Sacha Bull,Svetlana Dougoud,Olivier F. Clerc,Bernhard A. Herzog,Ronny R. Buechel,Oliver Gaemperli,Philipp A. Kaufmann +8 more
TL;DR: Coronary computed tomography angiography acquisition with diagnostic image quality is feasible at an ultra-low radiation dose of 0.21 mSv, e.g. in the range reported for a postero-anterior and lateral chest X-ray.
Journal ArticleDOI
Impact of cardiac magnetic resonance imaging on human lymphocyte DNA integrity
Michael Fiechter,Julia Stehli,Tobias A. Fuchs,Svetlana Dougoud,Oliver Gaemperli,Philipp A. Kaufmann +5 more
TL;DR: The present findings indicate that CMR should be used with caution and that similar restrictions may apply as for X-ray-based and nuclear imaging techniques in order to avoid unnecessary damage of DNA integrity with potential carcinogenic effect.
