Improved visualization of the coronary arteries using motion correction during vasodilator stress CT myocardial perfusion imaging.

Eur J Radiol 2019 May 2;114:1-5. Epub 2019 Mar 2.

Departments of Medicine and Radiology, University of Chicago Medical Center, Chicago, IL, United States. Electronic address:

Background: Vasodilator stress computed tomography perfusion (sCTP) imaging is complementary to coronary CT angiography (CCTA), used to determine the hemodynamic significance of coronary artery disease. However, it requires a separate image acquisition due to motion artifacts caused by higher heart rates during stress, resulting in increased iodine contrast dose and radiation. We sought to determine whether a novel motion correction algorithm applied to stress images would improve the visualization of the coronary arteries to potentially allow CCTA + sCTP evaluation in a single scan.

Usefulness of standard computed tomography pulmonary angiography performed for acute pulmonary embolism for identification of chronic thromboembolic pulmonary hypertension: results of the InShape III study.

J Heart Lung Transplant 2019 Mar 15. Epub 2019 Mar 15.

Department of Thrombosis and Hemostasis, Leiden University Medical Center, Leiden, The Netherlands. Electronic address:

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is often diagnosed after a long delay, even though signs may already be present on the computed tomography pulmonary angiogram (CTPA) used to diagnose a preceding acute pulmonary embolism (PE). In this setting of suspected acute PE, we evaluated the diagnostic accuracy of dedicated CTPA reading for the diagnosis of already existing CTEPH.

Methods: Three blinded expert radiologists scored radiologic signs of CTEPH on initial CTPA scans with confirmed acute PE in 50 patients who were subsequently diagnosed with CTEPH during follow-up (cases), and in 50 patients in whom sequential echocardiograms performed >2years after the acute PE diagnosis did not show any signs of pulmonary hypertension (controls).

Predicting asymptomatic coronary artery stenosis by aortic arch plaque in acute ischemic cerebrovascular disease: beyond the cervicocephalic atherosclerosis?

Chin Med J (Engl) 2019 Apr;132(8):905-913

Department of Radiology, Xuanwu Hospital, Capital Medical University, Beijing 100053, China.

Background: Asymptomatic coronary artery stenosis (ACAS) ≥50% is common in patients with acute ischemic cerebrovascular disease (AICVD), which portends a poor cardiovascular and cerebrovascular prognosis. Identifying ACAS ≥50% early may optimize the clinical management and improve the outcomes of these high-risk AICVD patients. This study aimed to investigate whether aortic arch plaque (AAP), an early atherosclerotic manifestation of brain blood-supplying arteries, could be a predictor for ACAS ≥50% in AICVD. 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.
