Noninvasive detection of coronary artery stenosis by multislice helical computed tomography.
Noninvasive detection of coronary artery stenosis with noninvasive imaging modalities (electron beam CT, MR angiography) has recently emerged. The use of helical CT in the visualization of epicardial coronary arteries is limited by cardiac motion artifacts due to long acquisition times and lack of an ECG trigger and is therefore reliable only in the determination of coronary graft patency. With...
متن کاملNoninvasive coronary artery imaging by multislice spiral computed tomography.
Although the excellent spatial resolution of multislice spiral computed tomography (MSCT) enables the coronary arteries to be visualized, its limited temporal resolution results in poor image reproducibility because of cardiac motion artifact (CMA) and hence limits its widespread clinical use. A novel retrospectively ECG-gated reconstruction method has been developed to minimize CMA. In 88 cons...
متن کاملNoninvasive coronary angiography with multislice computed tomography.
CONTEXT Multislice computed tomography (MSCT) has recently evolved as a modality for noninvasive coronary imaging. OBJECTIVE To assess the accuracy and robustness of MSCT vs the criterion standard of invasive coronary angiography for detection of obstructive coronary artery disease. DESIGN, SETTING, AND PATIENTS Prospective, single-center study conducted in a referral center setting in Germ...
متن کاملSpontaneous coronary artery dissection diagnosed by multislice computed tomography
Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome. Spontaneous coronary artery dissection can cause stable angina pectoris, unstable angina pectoris, acute myocardial infarction, cardiogenic shock and sudden cardiac death. It usually occurs in young to middle aged women. Atherosclerosis, peripartum period, and structural and inflammatory diseases affecting the ar...
متن کاملDetection of coronary artery stenoses by contrast-enhanced, retrospectively electrocardiographically-gated, multislice spiral computed tomography.
BACKGROUND Multislice spiral computed tomography (MSCT) with retrospectively ECG-gated image reconstruction permits coronary artery visualization. We investigated the method's ability to identify high-grade coronary artery stenoses and occlusions. METHODS AND RESULTS A total of 64 consecutive patients were studied by MSCT (4x1 mm cross-sections, 500-ms rotation, table feed 1.5 mm/rotation, in...
