Dual-energy CT for the detection of late enhancement in reperfused chronic infarction: a comparison to magnetic resonance imaging and histopathology in a porcine model
 |
To evaluate the performance of late enhancement dual-energy CT (LE-DECT) for the detection of infarcted myocardium as compared with 1.5-T late enhancement MRI (LE-MRI) in a porcine model of reperfused chronic myocardial infarction, using histopathology as standard of reference. Read more

Advanced techniques in cardiac CT imaging – further lowering the effective radiation dose (H. Alkadhi)
 |
Cardiac computed tomography (CT) represents a reliable and accurate modality for the diagnosis and exclusion of coronary artery disease. A huge number of studies have investigated the diagnostic performance of CT coronary angiography among different generations of CT scanners. Nevertheless, radiation doses still remain a matter of concern. Read more

Introduction of an individually optimized protocol for the injection of contrast medium for coronary CT angiography
 |
The aim of this study was to determine whether individually tailored protocols for the injection of contrast medium (CM) result in higher and more homogeneous vascular attenuation throughout the coronary arteries at coronary CT angiography compared with conventional injection protocols using fixed injection parameters.

Automatic selection of optimal systolic and diastolic reconstruction windows for dual-source CT coronary angiography
|
|
Abstract The aim of this study was to assess the performance of a motion-map algorithm that automatically determines optimal reconstruction windows for dual-source coronary CT angiography. In datasets from 50 consecutive patients, optimal systolic and diastolic reconstruction windows were determined using the motion-map algorithm. For manual determination of the optimal … Read more

New-onset heart failure caused by spontaneous papillary muscle rupture: Diagnosis with dual-source computed tomographic coronary angiography
|
|
Papillary muscle rupture is a rare cardiac emergency most frequently associated with acute myocardial infarction or blunt chest trauma. Once papillary muscle rupture has been diagnosed, urgent mitral valve replacement is indicated to correct the patient’s hemodynamic deterioration. Here we present the case of a patient with spontaneous, complete posterior … Read more
