Quantification of coronary artery calcium on the basis of dual-energy coronary CT angiography

posted by Balazs Ruzsics, M.D., PhD | Jul 31, 2013
Balazs Ruzsics, M.D., PhD

To evaluate the feasibility of using virtual noncontrast material-enhanced (VNC) CT series derived from dual-energy CT imaging studies for coronary artery calcium quantification. Read more

DSCT imaging of myocardial infarction

Balazs Ruzsics, M.D., PhD

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

DSCT Myocardial perfusion versus SPECT CT myocardial perfusion

posted by Balazs Ruzsics, M.D., PhD | Oct 22, 2009
Balazs Ruzsics, M.D., PhD

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

Comparison of Dual-Energy CT of the Heart With Single Photon Emission CT for Assessment of Coronary Artery Stenosis and of the Myocardial Blood Supply

posted by Balazs Ruzsics, M.D., PhD | Aug 21, 2009
Balazs Ruzsics, M.D., PhD

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

Coronary CT angiography: automatic cardiac-phase selection for image reconstruction

posted by Balazs Ruzsics, M.D., PhD | Jun 18, 2009
Balazs Ruzsics, M.D., PhD

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 most suitable … Read more

Clinical Competence in Cardiac CT – interactive DVD library

posted by Balazs Ruzsics, M.D., PhD | May 12, 2009

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

Myocardial Ischemia Diagnosed by Dual-Energy Computed Tomography: Correlation With Single-Photon Emission Computed Tomography

posted by Balazs Ruzsics, M.D., PhD | Nov 19, 2008
Balazs Ruzsics, M.D., PhD

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
