Post-mortem computed tomography (PMCT) and PMCT-angiography after transvascular cardiac intervention

Archives of Forensic Medicine and Criminology, 2014
Background and Purpose: During the last years, Post Mortem Computed Tomography (PMCT) has become an integral part of the autopsy. PMCT-angiography may augment PMCT.

The challenge to detect heart transplant rejection and transplant vasculopathy non-invasively – a pilot study

Journal of Cardiothoracic Surgery, 2009
Background Cardiac allograft rejection and vasculopathy are the main factors limiting long-term survival after heart transplantation. In this pilot study we investigated whether non-invasive methods are beneficial to detect cardiac allograft rejection ...

Proceedings of the cardiac – CT course held in Brussels on 16.11.2013

Journal of the Belgian Society of Radiology, 2013
With the advent of the multidetector computed tomography (CT), cardiac computed tomography angiography (CCTA) has become a viable non-invasive method to rule out obstructive coronary artery diseases (CAD) due to its excellent negative predictive value ...

Validation of OSEM algorithm for attenuation correction in cardiac SPECT studies [PDF]

, 2005
Photon attenuation is believed to be one of the major causes of artefacts in cardiac SPECT studies and therefore should be corrected to improve the specificity of cardiac SPECT imaging for the detection of coronary artery disease.
