Development of an Ex Vivo, Beating Heart Model for CT Myocardial Perfusion.

posted by Rozemarijn Vliegenthart, M.D., PhD | Aug 26, 2016
Rozemarijn Vliegenthart, M.D., PhD

Objective: To test the feasibility of a CT-compatible, ex vivo, perfused porcine heart model for myocardial perfusion CT imaging. Read more

Computed Tomography-Derived Parameters of Myocardial Morphology and Function in Black and White Patients With Acute Chest Pain.

posted by Rozemarijn Vliegenthart, M.D., PhD | Aug 19, 2016
Rozemarijn Vliegenthart, M.D., PhD

Our aim was to compare computed tomography (CT)–derived cardiac measurements between black patients with acute chest pain and age- and gender-matched white patients. Read more

Dynamic CT myocardial perfusion imaging identifies early perfusion abnormalities in diabetes and hypertension: insights from a multicenter registry.

posted by Rozemarijn Vliegenthart, M.D., PhD | Aug 16, 2016
Rozemarijn Vliegenthart, M.D., PhD

Objective: To analyze perfusion parameters derived from dynamic computed tomography perfusion imaging (CTPI) in patients with suspected coronary artery disease (CAD), and relationship with risk factors. Read more

The dream of a one-stop-shop: Meta-analysis on myocardial perfusion CT

posted by Rozemarijn Vliegenthart, M.D., PhD | May 27, 2015
Rozemarijn Vliegenthart, M.D., PhD

This meta-analysis shows considerable variation in techniques and reference standards for CT of myocardial blood supply. While CT seems sensitive and specific for evaluation of hemodynamically relevant CAD, studies so far are limited in size. Standardization of myocardial perfusion CT technique is essential. Read more

Correction of lumen contrast-enhancement influence on non-calcified coronary atherosclerotic plaque quantification on CT

posted by Rozemarijn Vliegenthart, M.D., PhD | Mar 19, 2015
Rozemarijn Vliegenthart, M.D., PhD

Lumen contrast-enhancement influences non-calcified atherosclerotic plaque Hounsfield-unit (HU) values in CT. This study aimed to construct and validate an algorithm to correct for this influence. Read more

Iterative image reconstruction techniques for CT coronary artery calcium quantification: comparison with traditional filtered back projection in vitro and in vivo

posted by Rozemarijn Vliegenthart, M.D., PhD | Mar 7, 2015
Rozemarijn Vliegenthart, M.D., PhD

To investigate in vitro and in vivo the use of image-based and raw data-based iterative reconstruction algorithms for quantification of coronary artery calcium by using the Agatston score and subsequent cardiac risk stratification. Read more

Coronary Artery Calcification Scoring with State-of-the-Art CT Scanners from Different Vendors Has Substantial Effect on Risk Classification

posted by Rozemarijn Vliegenthart, M.D., PhD | Feb 27, 2015
Rozemarijn Vliegenthart, M.D., PhD

Among individuals at intermediate cardiovascular risk, state-of the-art CT scanners made by different vendors produced substantially different Agatston scores, which can result in reclassification of patients to the high- or low-risk categories in up to 6.5% of cases. Read more

Hemodynamic significance of coronary stenosis by vessel attenuation measurement on CT compared with adenosine perfusion MRI

posted by Rozemarijn Vliegenthart, M.D., PhD | Feb 5, 2015
Rozemarijn Vliegenthart, M.D., PhD

We assessed the association between corrected contrast opacification (CCO) based on coronary computed tomography angiography (cCTA) and inducible ischemia by adenosine perfusion magnetic resonance imaging (APMR). Read more

Comparison of epicardial fat volume by CT in black versus white patients with acute chest pain

posted by Rozemarijn Vliegenthart, M.D., PhD | Dec 27, 2014
Rozemarijn Vliegenthart, M.D., PhD

We compared CT-derived volumes of epicardial adipose tissue (EAT), mediastinal adipose tissue (MAT), and pericoronary fat thickness (PFT) and correlations with CAD between black and white patients. Read more

Diagnostic performance of coronary CT angiography for stenosis detection according to calcium score: systematic review and meta-analysis

posted by Rozemarijn Vliegenthart, M.D., PhD | Dec 23, 2014
Rozemarijn Vliegenthart, M.D., PhD

A systematic review and meta-analysis to assess sensitivity and specificity of coronary CT angiography (CCTA) for significant stenosis at different degrees of coronary calcification. Read more

Comparison of the effect of iterative reconstruction versus filtered back projection on cardiac CT postprocessing

posted by Rozemarijn Vliegenthart, M.D., PhD | Oct 14, 2014
Rozemarijn Vliegenthart, M.D., PhD

To investigate the impact of iterative reconstruction in image space (IRIS) on image noise, image quality (IQ), and postprocessing at coronary CT angiography (cCTA) compared to traditional filtered back-projection (FBP). Read more

Accuracy of dual-energy CT for the measurement of iodine concentration using cardiac CT protocols: validation in a phantom model

posted by Rozemarijn Vliegenthart, M.D., PhD | Sep 5, 2014
Rozemarijn Vliegenthart, M.D., PhD

To assess the accuracy of dual-energy CT (DECT) for the quantification of iodine concentrations in a thoracic phantom across various cardiac DECT protocols and simulated patient sizes. Read more
