Coronary Angiography: The Promise

Coronary CT angiography (CTA) allows for noninvasive assessment of obstructive coronary artery disease (CAD), and is widely used for ruling out significant CAD in patients who have chest pain symptom. However, coronary calcium substantially attenuates X-ray penetration, causing “blooming” artifacts that obscure the coronary lumen on CTA. Coronary MRA has several important advantages over cardia...

Coronary CT angiography.

Advances in multidetector CT (MDCT) technology with submillimeter slice collimation and high temporal resolution permit contrast-enhanced imaging of coronary arteries and coronary plaque during a single breath hold. Appropriate patient preparation, detailed technical and technological knowledge with regard to recognition of typical imaging artifacts (such as beam hardening or motion artifacts),...

CT coronary angiography vs. invasive coronary angiography in CHD

SCIENTIFIC BACKGROUND Various diagnostic tests including conventional invasive coronary angiography and non-invasive computed tomography (CT) coronary angiography are used in the diagnosis of coronary heart disease (CHD). RESEARCH QUESTIONS The present report aims to evaluate the clinical efficacy, diagnostic accuracy, prognostic value cost-effectiveness as well as the ethical, social and leg...

Coronary CT angiography for acute chest pain.

Each year, more than 6 million people in the United States go to emergency departments because of acute chest pain. Some of them have coronary artery disease, but most have diseases that are unrelated to the heart or they have no discernible physiological conditions. The vast majority will undergo various diagnostic tests, and many will be held for observation and may be admitted to the hospita...
