the Accuracy and Safety of Coronary Artery Contrast-enhanced Magnetic Resonance Imaging With Polysaccharide Superparamagnetic Iron Oxide Nanoparticle

Clinical Study of Domestic Polysaccharide Superparamagnetic Iron Oxide Nanoparticle Injection for Coronary Artery Contrast-enhanced Magnetic Resonance Contrast-enhanced Angiography

This is a single-center, prospective, controlled and diagnostic clinical trial which will enroll 30 patients scheduled for coronary angiography in China.Patients will receive contrast-enhanced cardiac magnetic resonance with polysaccharide superparamagnetic iron oxide nanoparticle before percutaneous coronary angiography.In order to evaluate the safety of polysaccharide superparamagnetic iron oxide nanoparticle, patients will detect iron levels in peripheral and tissue before and after the examination.The main indicators of the study are the degree of coronary artery stenosis and the stability of coronary atherosclerotic plaque assessed by contrast-enhanced cardiac magnetic resonance with polysaccharide superparamagnetic iron oxide nanoparticle.

Inclusion Criteria:

• Age ≧ 18 years, < 75 years;
• Patients who planned coronary angiography ;

• Patients themselves or authorized families to sign informed consent voluntarily.

Exclusion Criteria:

• Patients who were allergic to iodine contrast agent or had allergic history or allergic constitution to iron and dextran;
• Patients who can ' t accept magnetic resonance examination because of psychological ( such as autism syndrome ) or physical reasons ( such as metal retention in the body );
