Coronary CT angiography versus standard emergency department evaluation for acute chest pain and diabetic patients: Is there benefit with early coronary CT angiography? Results of the randomized comparative effectiveness ROMICAT II trialCoronary CT angiography versus standard emergency department evaluation for acute chest pain and diabetic patients: Is there benefit with early coronary CT angi...

OBJECTIVES the purpose of the present study was to directly compare the diagnostic accuracy of magnetic resonance imaging (MRI) and multislice computed tomography (CT) for the detection of coronary artery stenosis. BACKGROUND both imaging modalities have emerged as potential noninvasive coronary imaging modalities; however, CT-unlike MRI-exposes patients to radiation and iodinated contrast ag...

PURPOSE To prospectively determine the accuracy of 64-section computed tomographic (CT) angiography for the depiction of coronary artery disease (CAD) that induces perfusion defects at myocardial perfusion imaging with single photon emission computed tomography (SPECT), by using myocardial perfusion imaging as the reference standard. MATERIALS AND METHODS All patients gave written informed co...

Invasive coronary angiography and computed tomography (CT) coronary angiography directly visualise coronary anatomy but do not provide information about the presence of inducible myocardial ischaemia. Due to its excellent negative predictive value CT coronary angiography is a suitable test to exclude significant coronary artery disease. However, given its high rate of false positive results par...

BACKGROUND The accuracy of multidetector computed tomographic (CT) angiography involving 64 detectors has not been well established. METHODS We conducted a multicenter study to examine the accuracy of 64-row, 0.5-mm multidetector CT angiography as compared with conventional coronary angiography in patients with suspected coronary artery disease. Nine centers enrolled patients who underwent ca...

The investigation and treatment of coronary disease impose a significant burden on health service resources. Catheter coronary angiography remains the gold standard for the investigation of suspected coronary disease. Given the invasive nature and high costs of invasive coronary angiography, there is an increased interest in noninvasive methods to image the lumen of the coronary arteries. Recen...

Noninvasive imaging of coronary artery disease is rapidly replacing angiography as the first line of investigation. Multislice CT is the non-invasive modality of choice for imaging coronary artery disease and provides high speed with good spatial resolution. CT coronary angiography in addition to detecting and characterising atherosclerotic coronary artery disease is also a good imaging tool fo...

BACKGROUND Computed tomographic (CT) angiography provides accurate noninvasive assessment for coronary artery stenosis. The ability of CT angiography to determine plaque morphology remains unclear. METHODS Twelve patients undergoing intravascular ultrasound for clinical indications underwent CT angiography for the evaluation of plaque morphology. Plaque morphology was classified as (1) soft, ...

PURPOSE To prospectively evaluate the effect of experience with coronary computed tomographic (CT) angiography on the capability to detect coronary stenoses of 50% or more. MATERIALS AND METHODS The institutional review board approved the study protocol. All patients gave consent to undergo CT angiography before conventional coronary angiography after being informed of the additional radiatio...
