Background-Noninvasive detection of coronary stenoses with electron beam CT (EBCT) after intravenous injection of contrast medium has recently emerged. We sought to determine the diagnostic accuracy of EBCT angiography in the clinical setting using conventional coronary angiography as the "gold standard." Methods and Results-Thirty-seven patients (30 men) were investigated. After intravenous injection of 150 mL of contrast medium, 40 to 60 consecutive transaxial tomograms, covering the proximal and middle parts of the coronary arteries, were obtained with ECG triggering at end diastole during breath-holding. Three-dimensional reconstructions of the proximal and middle parts of the arteries were compared with the conventional angiograms. Of the 259 proximal and middle coronary segments, 211 (81%) were analyzable by EBCT. Of the left anterior descending coronary artery (LAD) segments, 95% were assessable. Right coronary artery (RCA) and left circumflex artery (LCx) segments were assessable in 66% and 76%, respectively. Overall sensitivity and specificity to detect a Ͼ50% diameter stenosis were 77% and 94%, respectively. This was 82% and 92% for the LAD, 60% and 97% for the RCA, and 83% and 89% for the LCx (all figures based on assessable lesions). Conclusions-Intravenous EBCT coronary angiography is a promising coronary imaging technique. The technique is notyet robust enough to be an alternative to conventional coronary angiography. It can detect and rule out significant coronary artery disease of the left main proximal and mid portions of the LAD with good accuracy. (Circulation. 1998;98:2509-2512.)

‘High-risk’ or ‘vulnerable’ plaques in the coronary arteries have characteristics that make them more prone to disruption and subsequent thrombosis – the mechanisms of most acute coronary syndromes (ACS). There are a number of imaging modalities that are capable of visualizing these features. This article discusses invasive modalities for identifying ‘high-risk’ plaque such as intravascular ultrasound, coronary angioscopy, optical coherence tomography, near-infrared spectroscopy and coronary thermography. It also discusses the use of noninvasive modalities such as computed tomography MRI and ultrasound. When these imaging modalities are combined with standard cardiac risk factors and more novel markers of systemic inflammation and thrombogenicity we can improve our ability to identify the ‘high-risk’ patient.
