OBJECTIVES To conduct a meta-analysis and investigate the diagnostic value of 64-slice computed tomography (CT) angiography for diagnosing coronary artery disease (CAD) in patients. METHODS A comprehensive literature search from March 2005 to August 2014 was performed on the following databases: Cochrane Library; Medline; EmBase; PubMed; and BioMed Central database. As a reference standard, s...

OBJECTIVE To compare concentration of contrast medium for vascular opacification at ascending aorta using retrospective reconstruction of coronary CT angiography. STUDY DESIGN Retrospective study. MATERIAL AND METHOD Eighty-four patients undergoing coronary CT angiography with 16 multi-detector rows at Siriraj Hospital between September 2003 and July 2004 were included in this study. The pa...

Background Sixty-four and more-slice cardiac CT provides rapid and high quality coronary CT angiography for the majority of clinical needs of non-invasive evaluation of coronary artery. However, the recent advance of whole-heart coronary MRA has been able to provide high-quality of coronary MRA and also myocardial image in a reasonable scan time. The purpose of this study was to evaluate the cl...

Since the early 1960s, selective x-ray coronary angiography has provided the only means of visualizing the coronary arterial system in vivo. However, it has several disadvantages. First, the incidence, albeit relatively low, of so-called major adverse events (death, myocardial infarction, or stroke) during or within 24 hours of selective coronary angiography is reported to be 0.2% to 0.3%, and ...

A 69-year-old man presented with 2 weeks of exertional chest pressure typical of angina pectoris. An exercise stress test reproduced his symptoms and caused 1.5 mm of ST depression. Because a relative had a fatal event associated with invasive coronary angiography, he wished to have only noninvasive testing. Coronary computed tomographic (CT) angiography using 16-slice technology (Siemens Sensa...

BACKGROUND Noninvasive coronary angiography with the use of multislice computed tomography (CT) scanners is feasible with high sensitivity and negative predictive value; however, the radiation exposure associated with this technique is rather high. We evaluated coronary angiography using whole-heart 320-row CT, which avoids exposure-intensive overscanning and overranging. METHODS AND RESULTS ...

Recent technical advances in computed tomography (CT) have improved image quality, diagnostic performance and accuracy of coronary CT angiography (CCTA). Latest dose-reduction strategies reduce radiation dose to an acceptable level even lower than that from conventional coronary angiography. CCTA is a noninvasive imaging modality which can effectively show complex coronary artery anatomy, varia...

Methods Forty-seven patients had 1.5T steady state free precession, regadenoson stress perfusion CMR and either a ≤ 30% coronary narrowing by CT angiography (CTA) or a ≥70% stenosis by invasive coronary angiography (ICA). CMR perfusion pixel maps were generated by a modelconstrained deconvolution with and without the myocardial segmentation. The two independent observers were blinded to clinica...
