OBJECTIVE: Our objective was to study the ability of three-dimensional MR angiography with retrospective respiratory gating to reveal stenoses in proximal coronary arteries on source and projection images. CONCLUSION: Proximal coronary artery stenose

The purpose of this study was to examine the differential myocardial signal responses due to the blood oxygen level dependent (BOLD) effect in magnetic resonance imaging (MRI) under differing conditions of myocardial oxygen supply and demand. The sig

Using experimental and simulation studies, we assessed the applicability of pseudorandom binary hypoxic stimulation (PRBS) for estimating the dynamic respiratory response to a single breath of hypoxia. In experimental studies on rats we tested whethe

Intracoronary ultrasound (ICUS) not only allows visualization of the vessel lumen, it gives a unique view of the transmural components of the artery wall. Analysis of lumen and plaque volume is necessary for studying atherosclerotic disease progressi

Three-dimensional analysis using intracoronary ultrasound (ICUS) pull-back data provides the unique ability to quantitate lumen and atherosclerotic plaque volumes. Optimal data acquisition parameters for volumetric acquisition were established using

Current methods for 3-D reconstruction of intracoronary ultrasound images have limitations such as catheter motion in the transverse plane, unknown interslice distance (Z), and cyclic variations in lumen dimensions due to pulse pressure. The authors

An intracoronary ultrasound (ICUS) methodology for quantitative volumetric analysis of coronary atheroma was developed and validated. Sources of errors associated with volumetric ICUS were studied using computer simulations. These issues were address

Thin-section, three-dimensional (3D) gradient-echo magnetic resonance imaging of the coronary arteries was performed without and with retrospective respiratory gating in 12 healthy volunteers and one patient. In all examinations, results were improve

The ability to classify lesion composition accurately may be important for selecting or guiding interventional therapy and for understanding the pathophysiologic basis of individual lesions. To assess the usefulness of ultrasound in classifying lesio

Arterial distensibility is diminished by atherosclerosis. This process has not been well studied in the coronary arteries. The purpose of this study was to assess changes in coronary arterial distensibility in 4 groups of patients. Group I (n = 20) c
