Complementary CT coronary angiography after negative selective coronary angiography

Journal of the Belgian Society of Radiology, 2015
A 53-year-old male was admitted for typical acute chest pain. The ECG showed a mirror image of posterior myocardial ischemia. Initial biology was normal but cardiac markers (creatine kinase and troponin) rose later. Echocardiography did not reveal any hypokinetic myocardial segment. There was no left ventricular dysfunction or valvular disease.

Contrast Kinetics in CT Coronary Angiography. [PDF]

Indian J Radiol Imaging
AbstractComputed tomography coronary angiography (CTCA) is a technically demanding radiological investigation that requires adequate opacification of coronary arteries at peak aortic enhancement phase, with minimal or no contrast in the superior vena cava and right-sided cardiac chambers to avoid streak artifacts of dense contrast.

Postmortem coronary CT angiography [PDF]

Intensive Care Medicine, 2016
In the past few decades, the medical autopsy rate has markedly decreased owing to several factors such as the family’s refusal to provide consent, complexity of a time-consuming procedure, and fear of litigation in case of a missed diagnosis. On the other hand, CT and MR scans have increased the accuracy of diagnostic procedures and reduced the need ...
