Patient Based Bull's Eye Map Display of Coronary Artery and Ventricles From Coronary Computed Tomography Angiography.

Coronary computed tomography angiography is widely used in clinical practice. Although 3-dimensional (D) volume rendering is useful for interpretation of coronary path and territory, 2D output is common for image interpretation. Most picture archiving and communication system is incapable of manipulating 3D due to insufficient graphic specification. Thus, 2D bull's eye map display is frequently used in cardiac imaging. We developed a bull's eye map which emulated the anatomical information of individual cor...

Correlation and assessment of coronary artery luminal stenosis: Post-mortem computed tomography angiogram versus histopathology.

Post-mortem Computed Tomography (PMCT) allows non-invasive or minimally invasive detection of findings that may or may not be visible during conventional autopsy, however, it does not allow the investigator to draw any conclusions regarding patency of the vessel's lumen. To address this deficiency, Post-mortem Computed Tomography Angiography (PMCTA) utilizing different contrast media and techniques have been introduced with various studies looking at the correlation between PMCTA, autopsy (gross) findings a...

Biomarkers and their relative contributions to identifying coronary artery stenosis based on coronary computed tomography angiography in asymptomatic adults.

Coronary computed tomography angiography (CCTA) has emerged as an important, non-invasive imaging modality for the assessment of coronary vascular disease. However, CCTA as a screening tool still has issues with radiation exposure and cost in asymptomatic adults. In this study, we investigated the relationship between cardio-metabolic biomarkers and coronary artery stenosis on CCTA in asymptomatic, apparently healthy adults.

Assessing Cardiovascular Risk in the Pre-renal Transplant Population: Comparison of Myocardial Perfusion Imaging and Coronary Angiography with Risk Factor Stratification.

Patients with end stage renal disease (ESRD) have a higher incidence of coronary artery disease (CAD). Hence, it is crucial to evaluate CAD before renal transplantation. This study compares the utility of pharmacologic Single-Photon Emission Computed-Tomography (SPECT) imaging directly to coronary angiography for diagnosis of CAD with correlation to cardiovascular risk factors.

The impact of atherosclerotic risk factors on disease progression in patients with previously diagnosed nonobstructive coronary artery disease: factors affecting coronary artery disease progression.

Since coronary artery disease (CAD) is a slow progressive disease, management and appropriate follow-up of patients with nonobstructive coronary artery disease (NOCAD) remains challenging, and there are no clear guidelines recommending a follow-up strategy and indications for repeat invasive coronary angiography (ICA). We investigated the predictors of the development of obstructive CAD in patients with previously diagnosed NOCAD.
