Dual energy CT for the assessment of reperfused chronic infarction – a feasibility study in a porcine model
 |
To evaluate the feasibility and performance of dual energy CT during arterial phase in coronary CT angiography for the detection of chronic infarction compared with late enhancement MRI (LE-MRI) and histopathology in a porcine model of reperfused myocardial infarction. Read more

High-pitch spiral CT: effect on image quality and radiation dose in pediatric chest CT
 |
We evaluated a new, subsecond high-pitch scan mode (HPM), which obviates the need of sedation and to hold the breath. Read more

Dose reduction in abdominal CT: intraindividual comparison of image quality of full-dose standard and half-dose iterative reconstructions with DSCT
|
|
We sought to evaluate the image quality of iterative reconstruction in image space (IRIS) in half-dose (HD) datasets compared with full-dose (FD) and HD filtered back projection (FBP) reconstruction in abdominal CT. Read more

Detection of coronary artery stenoses by low-dose, prospectively ECG-triggered, high-pitch spiral coronary CT angiography
|
|
We sought to evaluate the diagnostic accuracy of a new prospectively electrocardiogram (ECG)-triggered high-pitch scan mode for coronary CTA, which allows an effective dose of less than 1 mSv. Read more

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
