Triphasic Contrast Agent Injection in 64-MDCT Coronary Artery Angiography
Purpose: To evaluate image quality and cardiovascular enhancement after triphasic injection in 64-slice-CT coronary angiography (c-CTA). Methods: c-CTA of twenty-two asymptomatic patients following triphasic injection (65ml-contrast bolus + mixed 30mlcontrast and 20ml-saline bolus + 50ml-saline chaser) were retrospectively reviewed. Attenuation in the great vessels, cardiac chambers, and corona...
متن کاملCoronary Artery Calcium Quantification in Contrast-enhanced Computed Tomography Angiography
Coronary arteries are the blood vessels supplying oxygen-rich blood to the heart muscles. Coronary artery calcium (CAC), which is the total amount of calcium deposited in these arteries, indicates the presence or the future risk of coronary artery diseases. Quantification of CAC is done by using computed tomography (CT) scan which uses attenuation of xray by different tissues in the body to gen...
متن کاملComplementary role of transoesophageal echocardiography to coronary angiography in the assessment of coronary artery anomalies.
OBJECTIVE To examine the role of transoesophageal echocardiography in the assessment of patients with coronary artery anomalies. BACKGROUND Coronary artery anomalies are difficult to detect clinically. Most are benign but some may produce symptoms that can be life threatening. Until recently the non-invasive assessment of coronary artery anomalies has been limited. METHODS The data base of ...
متن کاملAutomated coronary artery tracking in contrast-enhanced whole-heart coronary magnetic resonance angiography at 3.0T
Background Contrast-enhanced whole heart coronary Magnetic Resonance Angiography (MRA) at 3.0 Tesla (T) allows noninvasive detection of obstructive stenoses. Automated vessel segmentation and tracking of centerlines is important for quantitative measurement of stenosis, but remains challenging for coronary MRA. We aimed to develop and validate automated coronary artery segmentation from contras...
