Clinical Trial Summary

This study will assess the use of position emission tomography/magnetic resonance imaging (PET/MRI) using ultra-small-superparamagnetic particles of iron oxide (USPIO) as a contrast agent in patients with coronary artery disease.

Description:

Positron emission tomography/magnetic resonance imaging (PET/MRI) has the potential to provide detailed information on coronary artery anatomy, the presence of coronary artery stenosis, the composition of atherosclerotic plaque using MRI tissue characterisation and information about the underlying biological processes using targeted PET tracers. Ultra-small-superparamagnetic particles of iron oxide (USPIO) have a long blood pool half-life so are an ideal contrast agent for PET/MRI imaging. This study will assess the use of PET/MRI with USPIO in patients with stable coronary artery disease and recent acute myocardial infarction.
