Coronary CT angiography (CTA) is a highly accurate test for the diagnosis of coronary artery disease (CAD), with its use guided by numerous contemporary appropriate use criteria and clinical guidelines. Unique among non-invasive tests for CAD, coronary CTA provides direct visualization of coronary atherosclerosis for the assessment of angiographic stenosis, as well as validated measures of plaque vulnerability. Long-term studies now clearly demonstrate that the absence of CAD on coronary CTA identifies a patient that is at very low risk for future cardiovascular events...

Computed tomography (CT) has become an important modality in the evaluation of coronary artery disease (CAD). The tremendous technological advances in CT in the last two decades has made it possible to obtain high quality images of coronary arteries with high spatial and temporal resolutions. Multiple trials have confirmed the accuracy of CT compared to invasive catheter angiography. CT is also able to evaluate beyond the lumen in characterizing and quantifying atherosclerotic plaques, including evaluation of high risk features...

A 50-year-old man presented to the emergency department with interscapular pain, diaphoresis and restlessness. Initial examination raised the possibility of aortic dissection; however, the CT scan did not concur with the diagnosis. An ECG showed ST segment elevation in leads V1-V6 and echocardiography showed severe left ventricular systolic dysfunction. Coronary angiography through the right femoral artery was attempted but the diagnostic catheter could not be advanced to the ascending aorta. Radiocontrast injection showed complete obstruction of the descending aorta...

Cardiac computed tomography angiography (CCTA) studies have risen concern of radiobiological effects over the patients. Therefore, estimating radiation doses absorbed during CCTA is important. In this study, we compared radiation dose and image quality by using three different retrospective electrocardiography (ECG) protocols. A total of 123 patients undergoing CCTA were divided in three different groups. We used full-dose modulation (CareDose4D) technique in group (1); fixed tube current 200 mAs for group (2); and in group (3), chest circumference was used to adapt tube current (180-200 mAs) and tube potential (100-120 kVp)...

A 42-year-old woman presented to the emergency department with chest pain. Acute coronary syndrome was ruled out. During dobutamine stress echocardiography (DSE), she developed chest pain and inferior ST elevation. Emergent coronary angiography revealed no culprit lesions but did show an anomalous right coronary artery (RCA). Coronary CT angiography (CCTA) confirmed an anomalous RCA arising from the left coronary cusp with a slit-like ostium and interarterial course (ARCA-LCC-IA). Herein, we review the extant literature on ARCA-LCC-IA, its clinical presentation, the vital role of CTA and MRI in its diagnosis, as well as challenges and controversies surrounding management...

BACKGROUND: Measuring local RV function in adult congenital heart disease (ACHD) with echocardiography or MRI is challenging because of the complex geometry and existing pacing devices. Visual assessment of ventricular function via low-dose cardiac CT has been recently performed. This pilot study assessed whether low-dose 4D cine CT combined with automatic measurement of regional shortening could quantify right-ventricular function in ACHD patients. METHODS: Seven patients with Tetralogy of Fallot either contraindicated for MRI or assessed for coronary artery disease and seven non-congenital patients were imaged with ECG-gated cardiac CT utilizing a 320-detector row scanner...

Harmonic mode ultrasound with injection of a contrast enhancement agent allows visualization of mobile microbubbles in the carotid plaque corresponding to neovessels secondary to an inflammation or hypoxia. These neovessels could be considered "precursor" markers of the vulnerable plaque. The aim of this work was to give an update on ultrasound contrast imaging acquisition in the exploration of carotid artery both for atheromatous lesions and for large vessel vasculitis. A precise description of the material to be used, the image acquisition methodology and the environmental conditions is discussed, emphasizing the pitfalls to be avoided as well as proper image interpretation...
