VALIDATION OF A NOVEL METHOD FOR CARDIAC OUTPUT ESTIMATION BY CT CORONARY ANGIOGRAPHY

Validation of a Novel Method for Cardiac Output Estimation by CT Coronary Angiography

Background: Cardiac output can be estimated during retrospectively gated CT coronary angiography by anatomically determining left ventricular volumes; prospective triggering to minimize radiation precludes this methodology. We propose an alternative method for cardiac output estimation based on preclinical models suggesting that cardiac output may be inversely related to contrast washout from t...

Novel 320‐slice multislice CT angiography as a gatekeeper for invasive coronary angiography

The diagnostic accuracy of 64‐slice CTA, currently the most widely used CTA system, has been well established by several multicenter studies [4–6]. In a recent prospective multicenter, multivendor trial by Meijboom and coworkers, high diagnostic accuracy of 64‐slice CTA was observed in the evaluation of 360 symptomatic patients with acute and stable angina [5]. On a per‐patient basis, the sensi...

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),...

Validation of a Novel Clinical Prediction Score for Severe Coronary Artery Diseases before Elective Coronary Angiography

OBJECTIVES Coronary artery disease (CAD) severity is associated with patient prognosis. However, few efficient scoring systems have been developed to screen severe CAD in patients with stable angina and suspected CAD before coronary angiography. Here, we present a novel scoring system for CAD severity before elective coronary angiography. METHODS Five hundred fifty-one patients with stable an...
