In particular, there is a concern that CTCA may increase the number of future invasive coronary angiograms. We studied patients referred to the CTCA service in our centre and compared their predicted risk, prior stress testing and subsequent investigations to the NICE guidance and with data from ...
New CAD was diagnosed when patients had either angiographic evidence of obstructive CAD on a CCTA (ie, >50% obstruction) and/or angiographic evidence of obstructive CAD on an invasive coronary angiogram (ie, >50% obstruction). If these data were not provided, new CAD was diagnosed if any ...
They received energy spectrum CT coronary angiogram imaging examination within 48 h after admission for incidence of carotid atherosclerostic plaque and plaque types. Results Comparison of risk factors between the two groups showed hypertension and coronary heart disease were correlated with acute ischemic...
DEEPVESSEL FFR is a AI-enabled, non-invasive CT fractional flow reserve (FFRCT) analysis. It is an augmentative physiological functional assessment of the coronary arteries using coronary computer tomography angiograms. The software can reduce unnecessary invasive testing, improve patient safety, and lo...

discomfort; a history of previous myocardial infarction (MI); a previous positive exercise tolerance test; previous coronary artery bypass graft surgery (CABG) or percutaneous transluminal coronary angioplasty or a previous coronary angiogram showing 50% stenosis of a major epicardial coronary vessel (26...
A CT angiogram can show two- and three-dimensional images of the heart and blood vessels. A spiral CT scan helps in faster scanning of the lungs than a regular CT. this scan is often recommended to screen for lung cancer in patients who are above the age of 55 and who have a high ...
CT brain demonstrated bilateral and symmetric hypoattenuation within the medial thalami with normal CT angiogram and CT venogram. Brain MRI showed bilateral hemorrhagic rim-enhancing lesions in the thalami, medial temporal lobes, and subinsular regions. The authors concluded that the patient presented ...
A practical guide to reading CT coronary angiograms-- how to avoid mistakes when assessing for coronary stenoses. Int J Cardiovasc Imaging. 2007;23(5):617-33.A practical guide to reading CT coronary angiograms—How to avoid mistakes when assessing for coronary stenoses[J] . John W. M. ...
A CT scan of the heart can help predict a patient's risk of heart attack by checking for blockage in the coronary arteries. Typical costs: There are two types of heart CT most commonly used; the less invasive calcium scoring heart CT scan, which uses computerized tomography is used to det...
