Comparison of image quality between photon-counting detector CT and energy-integrating detector coronary CT angiography in heart transplant patients Open
This study aims to compare the image quality between photon-counting detector computed tomography (PCD-CT) and energy-integrating CT (EID-CT) for coronary artery visualization post-heart transplant (HTx) patients, using a paired comparison…

Diagnostic performance of high and ultra-high-resolution photon counting CT for detection of coronary artery disease in patients evaluated for transcatheter aortic valve implantation Open
We assessed the diagnostic performance of both ultra-high-resolution (UHR) and high-resolution (HR) modes of photon-counting detector (PCD)-CT within the confines of standard pre-TAVI CT scans, as well as the performance of UHR mode adjust…

Temporal changes in CT-derived fractional flow reserve in patients after heart transplantation Open
Background Adding functional information by CT-derived fractional flow reserve (FFRct) to coronary CT angiography (CCTA) and assessing its temporal change may provide insight into the natural history and physiopathology of cardiac allograf…

Photon-counting CT: Review of initial clinical results Open
Photon-counting computed tomography (PCCT) is a new technology that enables higher spatial resolution compared to conventional CT techniques, energy resolved imaging and spectral post-processing. This leads to improved contrast-to-noise ra…

Photon-counting Detector CT in Patients Pre- and Post-Transcatheter Aortic Valve Replacement Open
Photon-counting detector CT (PCD CT) has increasingly garnered interest in cardiothoracic imaging due to its high spatial resolution and ability to perform spectral imaging. CT plays an important role in the planning and postprocedural ass…
