Myocardial Viability by Dual-Energy Delayed Enhancement Computed Tomography

Early assessment of myocardial viability by the use of delayed enhancement computed tomography after primary percutaneous coronary intervention.

OBJECTIVES We sought to explore the relationship between established parameters of reperfusion and the extent of myocardial damage measured by the delayed enhancement (DE) of iodinated contrast by multidetector computed tomography (MDCT) immediately after primary percutaneous coronary intervention (PCI). BACKGROUND Early detection of myocardial viability should be valuable for risk stratifica...

Diagnosis of acute myopericarditis by delayed-enhancement multidetector computed tomography.

Images in cardiovascular medicine. Myocardial ischemia diagnosed by dual-energy computed tomography: correlation with single-photon emission computed tomography.

For decades, dual-energy imaging has been used for tissue differentiation with several x-ray–based imaging modalities, exploiting the fact that the tissues in the human body show different absorption characteristics when penetrated with different x-ray spectra, spectra that are typically generated by different kV settings of the x-ray tube. Recently, dual-source computed tomography (CT) with 2 ...

Dynamic myocardial perfusion imaging by dual-source computed tomography.

We report a dual-source computed tomography study of dynamic and quantitative myocardial perfusion in a 44-year-old patient with previous documented coronary artery disease. Quantitatively, the tomography showed myocardial perfusion deficit in the territories with significant coronary stenosis, confirmed by computed tomography angiography and conventional angiography. Dual-source computed tomog...
