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

In preliminary studies DSCT provides robust image quality over a wide range of heart rates and excludes CAD with high accuracy. The aim of the present study was to evaluate the reproducibility of these results in a large, unselected and consecutive group of patients scheduled for invasive coronary angiography (ICA).

CT may have potential for the integrative assessment of all aspects of coronary artery disease including coronary artery morphology, cardiac function, perfusion, and viability with a single modality. Read more

Iterative image reconstruction techniques appear superior to FBP for the evaluation of heavily calcified vessels with cCTA and should be preferentially used in patients with high calcium scores. Read more

Obviating the need for an additional image acquisition during rest holds promise to substantially reduce radiation doses involved with CT-based myocardial perfusion imaging. Read more

To compare the dose estimates and image quality of Dual Energy CT (DECT), Dual Source CT (DSCT) and 16-slice CT for coronary CT angiography (cCTA). Read more

For the detection of myocardial perfusion deficits seen on SPECT, DECT-based analysis of myocardial iodine distribution is superior to single-energy CT spectra. Read more
