Diagnostic performance of coronary angiography by 64-row CT.
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...
متن کاملdiagnostic performance of multislice ct coronary angiography in the assessment of significant coronary artery disease
the use of noninvasive assessment tools such as multi-slice ct coronary angiography (msct-ca-ca) is recently considered mainly because it offers safety, patient convenience, and faster performance. the aim of the present study was to determine the ability of msct-ca-ca for the detection of significant stenoses in the coronary arteries, in comparison to conventional invasive coronary angiography...
متن کاملDiagnostic optimization of coronary CT angiography.
m c Combined evaluation of coronary anatomy and myocardial ischemia has become the holy grail of noninvasive diagnostic imaging. Several approaches, such as hybrid imaging combining coronary computed tomography angiography (CTA) for anatomy and stress-rest nuclear imaging for perfusion, are adding to the complexity, cost, and radiation burden of both techniques. In theory, a single imaging devi...
متن کاملCoronary 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),...
متن کاملDiagnostic Value of 64-Slice Dual-Source CT Coronary Angiography in Patients with Atrial Fibrillation: Comparison with Invasive Coronary Angiography
OBJECTIVE We wanted to evaluate the image quality and diagnostic value of 64-slice dual-source computed tomography (DSCT) coronary angiography in patients with atrial fibrillation (Afib). MATERIALS AND METHODS The coronary arteries of 22 Afib patients seen on DSCT were classified into 15 segments and the imaging quality (excellent, good, moderate and poor) and significant stenoses (≥ 50%) wer...
