Age- and gender-adjusted percentiles for number of calcified plaques in coronary artery calcium scanning.

J Cardiovasc Comput Tomogr 2018 Dec 17. Epub 2018 Dec 17.

Department of Imaging, Cedars-Sinai Medical Center, Cedars-Sinai Heart Institute, Los Angeles, CA, USA. Electronic address:

Background: Age- and gender-adjusted percentiles of coronary artery calcium (CAC) score are commonly reported to compare a patient's coronary atherosclerosis burden to that of others of the same age and gender. The number of calcified plaques (numCP) detected on CAC scanning, a measure of plaque diffusivity, is associated with increased cardiovascular risk and, in the intermediate CAC range, adds to the CAC score in predicting mortality. This study aims to develop adjusted percentiles for numCP to provide a better context for understanding CAC scan findings. Read More

Effect of image reconstruction algorithms on volumetric and radiomic parameters of coronary plaques.

J Cardiovasc Comput Tomogr 2018 Nov 12. Epub 2018 Nov 12.

Cardiovascular Imaging Research Group, Heart and Vascular Center, Semmelweis University, Budapest Hungary, 68. Varosmajor Street, 1122, Budapest, Hungary.

Background: Volumetric and radiomic analysis of atherosclerotic plaques on coronary CT angiography have been shown to predict high-risk plaque morphology and to predict patient outcomes. However, there is limited information whether image reconstruction algorithms and preprocessing steps (type of binning, number of bins used for discretization) may influence parameter values.

Methods: We retrospectively identified 60 coronary lesions on coronary CT angiography (CTA). Read More

This expert consensus statement from the Society of Cardiovascular Computed Tomography (SCCT) provides an evidence synthesis on the use of computed tomography (CT) imaging for diagnosis and risk stratification of coronary artery disease in women. From large patient and population cohorts of asymptomatic women, detection of any coronary artery calcium that identifies females with a 10-year atherosclerotic cardiovascular disease risk of >7.5% may more effectively triage women who may benefit from pharmacologic therapy.

Quantitative evaluation of non-ischemic dilated cardiomyopathy by late iodine enhancement using rapid kV switching dual-energy computed tomography: A feasibility study.

J Cardiovasc Comput Tomogr 2018 Oct 29. Epub 2018 Oct 29.

Division of Radiology, Department of Pathophysiological Therapeutic Science, Tottori University Faculty of Medicine, Yonago City, Tottori 683-8504, Japan.

Objectives: The aim of this study was to evaluate the feasibility of myocardial iodine density and extracellular volume fraction (ECV) from delayed iodine density images using dual-energy computed tomography (DECT) for differentiation between non-ischemic dilated cardiomyopathy (NIDCM) patients and normal subjects.

Methods: Forty-six subjects were imaged, including 35 normal subjects and 11 patients with NIDCM. All subjects underwent myocardial delayed enhancement (MDE) imaging on rapid-kVp switching DECT. Read More

Artificial intelligence machine learning-based coronary CT fractional flow reserve (CT-FFR): Impact of iterative and filtered back projection reconstruction techniques.

J Cardiovasc Comput Tomogr 2018 Oct 26. Epub 2018 Oct 26.

Division of Cardiovascular Imaging, Department of Radiology and Radiological Science, Medical University of South Carolina, Charleston, SC, USA; Department of Radiology & Imaging Sciences, Emory University, Atlanta, GA, USA.

Background: The influence of computed tomography (CT) reconstruction algorithms on the performance of machine-learning-based CT-derived fractional flow reserve (CT-FFR) has not been investigated. CT-FFR values and processing time of two reconstruction algorithms were compared using an on-site workstation.

Methods: CT-FFR was computed on 40 coronary CT angiography (CCTA) datasets that were reconstructed with both iterative reconstruction in image space (IRIS) and filtered back-projection (FBP) algorithms. Read More

Left atrial appendage closure guided by 3D computed tomography printing technology: A case control study.

J Cardiovasc Comput Tomogr 2018 Oct 26. Epub 2018 Oct 26.

Centro Cardiologico Monzino, IRCCS, Milan, Italy. Electronic address:

Background: We sought to evaluate the additional value of left atrial appendage (LAA) 3D printing derived from computed tomography (CCT) in determining the size for LAA occlusion (LAAO) devices as compared to standard measurement by using occurrence of LAA leak as endpoint.

Methods: We evaluated 6 patients with LAA leak (cases) and 14 matched patients without LAA leak (controls) after LAAO. For each group, a patient-specific 3D printed model of LAA was manufactured using CT pre-operative images. Read More

Optimized interpretation of fractional flow reserve derived from computed tomography: Comparison of three interpretation methods.

J Cardiovasc Comput Tomogr 2018 Oct 25. Epub 2018 Oct 25.

Department of Radiology, Iwate Medical University, 19-1, Uchimaru, Morioka, #0208505, Japan. Electronic address:

Background: An optimal system for interpreting fractional flow reserve (FFR) values derived from CT (FFR) is lacking. We sought to evaluate performance of three FFR measurements in detecting ischemia by comparing them with invasive FFR.

Methods: For 73 vessels in 50 patients who underwent coronary CT angiography (CCTA) and FFR analysis followed by invasive FFR, the greatest diameter stenosis on CCTA, FFR difference between distal and proximal to the stenosis (ΔFFR), FFR 2 cm distal to the stenosis (lesion-specific FFR), and the lowest FFR in distal vessel tip were calculated.
