Electro-cardiogram (ECG)-gated dual energy computed tomography (DECT) of the heart may enable spectral analysis of the myocardium for areas of decreased blood supply in addition to morphological assessment for coronary artery stenosis. We used DECT for evaluating a 49-year-old woman with known coronary artery disease and new onset chest pain. She … Read more

The following question has been sent by Dr. Shrinivas Desai: DSCT Myocardial perfusion versus SPECT CT myocardial perfusion: Jaslok Hospital in mumbai, India is buying Siemens DSCT (Flash Definition Dual source Dual energy). We already have a SPECT on which thallium myocardial perfusion is done. The nuclear medicine department is considering acquiring … Read more

In conclusion, our initial experience suggests that DECT, as a single examination, might be promising for the integrative analysis of the coronary artery morphology and the myocardial blood supply and is in good agreement with ICA and SPECT. Read more

Abstract We evaluated an algorithm for automatic selection of the cardiac phase with the least motion for image reconstruction at coronary computed tomography (CT) angiography (CCTA). We analyzed data of 100 patients (49 female, mean age 59 years) who had undergone retrospectively ECG-gated CCTA. Two experienced observers visually identified the … Read more

Clinical Competence in Cardiac CT is an interactive self assessment training tool on DVD. The goal of this home study program is to train doctors to meet their ACCF/AHA Level 1 and Level 2 Credentialing requirements in Cardiac CT with Case review and CME credit. The four volume library features 160 … Read more

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 … Read more
