Image reconstruction in cardiovascular CT: Part 2 - Iterative reconstruction; potential and pitfalls.

J Cardiovasc Comput Tomogr 2019 Apr 16. Epub 2019 Apr 16.

Department of Cardiovascular CT, Royal Brompton Hospital, London, UK. Electronic address:

The use of IR in CT previously has been prohibitively complicated and time consuming, however improvements in computer processing power now make it possible on almost all CT scanners. Due to its potential to allow scanning at lower doses, IR has received a lot of attention in the medical literature and has become a successful commercial product. Its use in cardiovascular CT has been driven in part due to concerns about radiation dose and image quality. Read More

Multimodality imaging of left atrium in patients with atrial fibrillation.

J Cardiovasc Comput Tomogr 2019 Mar 30. Epub 2019 Mar 30.

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

Atrial fibrillation (AF) is the most common arrhythmia worldwide associated with significant morbidity and mortality and represents a significant health care burden. Goals of AF treatment include prevention of cardioembolic stroke using anticoagulation and device therapy and restoration of sinus rhythm using antiarrhythmic drugs or catheter ablation techniques. A comprehensive assessment of cardiac chamber size and function is often started with echocardiography as a first line diagnostic imaging strategy. Read More

Coronary atherosclerosis imaging by CT to improve clinical outcomes.

J Cardiovasc Comput Tomogr 2019 Mar 29. Epub 2019 Mar 29.

Royal Brompton and Harefield NHS Foundation Trust Departments of Cardiology and Radiology, London, UK; National Heart and Lung Institute, Faculty of Medicine, Imperial College, London, UK.

Coronary artery disease remains an important cause of morbidity and mortality world-wide. Coronary Computed Tomography Angiography (CCTA) has excellent diagnostic accuracy and the identification and stratification of coronary artery disease is associated with improved prognosis in multiple studies. Recent randomized controlled trials have shown that in patients with stable coronary artery disease, CCTA is associated with improved diagnosis, changes in investigations, changes in medical treatment and appropriate selection for revascularization.

State-of-the-art review article. Atherosclerosis affecting fat: What can we learn by imaging perivascular adipose tissue?

J Cardiovasc Comput Tomogr 2019 Mar 29. Epub 2019 Mar 29.

Department of Imaging and Medicine, Cedars-Sinai Medical Center, Los Angeles, CA, USA.

Perivascular adipose tissue (PVAT) surrounding the human coronary arteries, secretes a wide range of adipocytokines affecting the biology of the adjacent vascular wall in a paracrine way. However, we have recently found that PVAT also behaves as a sensor of signals coming from the vascular wall, to which it reacts by changing its morphology and secretory profile. Indeed, vascular inflammation, a key feature of vascular disease pathogenesis, leads to the release of inflammatory signals that disseminate into local fat, inducing local lipolysis and inhibiting adipogenesis.

Relationship of exercise to coronary artery disease extent, severity and plaque type: A coronary computed tomography angiography study.

J Cardiovasc Comput Tomogr 2019 Feb 27. Epub 2019 Feb 27.

Department of Internal Medicine III, Cardiology, Innsbruck Medical University, Austria. Electronic address:

Background: While exercise has been associated with favorable coronary artery disease (CAD) outcomes, the relationship between endurance exercise levels and CAD findings has not been well explored.

Purpose: To evaluate the relationship of endurance exercise to CAD findings by coronary computed tomographic angiography (CCTA).

Methods: We evaluated consecutive patients referred to CCTA who filled out a survey instrument between 2015 and 2017, and who graded their level of weekly endurance exercise as: none, low (1-2 times per week), moderate (3-5 times per week) or high (5-7 times per week); along with the number of hours per week engaged in exercise as: low (<30 min), moderate (1 h) or high (>1-3 h).

Effect of tube potential and luminal contrast attenuation on atherosclerotic plaque attenuation by coronary CT angiography: In vivo comparison with intravascular ultrasound.

J Cardiovasc Comput Tomogr 2019 Feb 12. Epub 2019 Feb 12.

Department of Imaging, Cedars-Sinai Medical Center, Los Angeles, CA, USA; The Heart Institute, Cedars-Sinai Medical Center, Los Angeles, CA, USA.

Background: It has been shown that CT attenuation of noncalcified plaques depends on luminal contrast attenuation (LCA). Although tube potential (kilovolt [kV]) has been shown to exert influence on plaque attenuation through LCA as well as its direct effects, in-vivo studies have not investigated plaque attenuation at lower tube potentials less than 120 kV. We sought to evaluate the effect of kV and LCA on thresholds for lipid-rich and fibrous plaques as defined by intravascular ultrasound (IVUS). Read More

Quantified dual energy computed tomography perfusion imaging using myocardial iodine concentration: Validation using CT derived myocardial blood flow and invasive fractional flow reserve in a porcine model.

J Cardiovasc Comput Tomogr 2019 Jan 30. Epub 2019 Jan 30.

Division of Cardiology, Vancouver General Hospital, 2775 Laurel Street, Vancouver, BC, V5Z 1M9, Canada; Department of Radiology, Vancouver General Hospital, 2775 Laurel Street, Vancouver, BC, V5Z 1M9, Canada.

Background: Myocardial CT perfusion imaging with dual energy (DE-CTP) can produce myocardial iodine perfusion maps.

Impact of anatomical features of the left atrial appendage on outcomes after cryoablation for atrial fibrillation.

J Cardiovasc Comput Tomogr 2019 Jan 4. Epub 2019 Jan 4.

Department of Cardiology, Hacettepe University Faculty of Medicine, Ankara, Turkey.

Aims: Pulmonary vein isolation (PVI) using cryoballoon has been accepted as a safe and effective method for treatment of atrial fibrillation (AF). Despite advances in catheter-based technologies, some patients still experience AF recurrence. In this study, we aimed to compare left atrial appendage (LAA) morphology in AF patients and subjects with sinus rhythm and also investigate the association between LAA morphology and success of PVI using cryoballoon in subjects with AF.

Objectives: To evaluate the feasibility of coronary computed tomography angiography (CCTA) in patients with free-breathing using 16-cm z-coverage CT with motion correction algorithm.

Methods: 616 patients underwent CCTA without heart rate control. 325 examinations were performed during breath-holding (group A), and the remaining 291 were performed during free-breathing (group B). Read More

Estimation of myocardial fibrosis in humans with dual energy CT.

J Cardiovasc Comput Tomogr 2018 Dec 18. Epub 2018 Dec 18.

The Ohio State University Davis Heart and Lung Research Institute, 473 W. 12th Ave, Columbus, OH, 43210, USA. Electronic address:

Background: The current clinical standard for in vivo imaging of myocardial fibrosis is contrast-enhanced cardiac magnetic resonance (CMR). We sought to validate a novel non-contrast dual energy computed tomography (DECT) method to estimate myocardial fibrosis in patients undergoing CMR with contrast.

Methods: All subjects underwent non-contrast, prospectively-triggered cardiac DECT on a single source scanner with interleaved acquisition between tube voltages of 80 and 140 kVp. Read More

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

Electronic address:

Background: Data on the impact of glycemic status on coronary plaque progression have been limited. This study evaluated the association between glycemic status and coronary plaque volume change (PVC) using coronary computed tomography angiography (CCTA).

Methods: A total of 1296 subjects (61 ± 9, 56. Read More
