Imaging of Coronary Stent by Multislice Helical Computed Tomography

[Evaluation of coronary stent restenosis with multislice computed tomography].

Noninvasive 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...

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...

Virtual coronary angioscopy using multislice computed tomography.

BACKGROUND With faster image acquisition times and thinner slice widths, multislice detector computed tomography (MSCT) allows visualisation of human coronary arteries with diagnostic image quality. In addition to conventional axial slices, virtual coronary angioscopies (VCA) can be reconstructed using MSCT datasets. OBJECTIVE To evaluate the feasibility of reconstructing VCA and to determine...

Natural history of coronary atherosclerosis by multislice computed tomography.

OBJECTIVES This study sought to analyze the natural history of coronary atherosclerosis by multislice computed tomography (MSCT) and assess the serial changes in coronary plaque burden, lumen dimensions, and arterial remodeling. BACKGROUND MSCT can comprehensively assess coronary atherosclerosis by combining lumen and plaque size parameters. METHODS Thirty-two patients with acute coronary s...
