Atherosclerotic coronary artery disease is the main cause of heart attack. Unlike plaques in carotid arteries, the atherosclerotic plaques in coronary arteries are difficult to be detected using conventional MRI techniques with surface coils. To solve this problem, a 0.014-inch intracoronary MR imaging-guidewire (a loopless RF coil) was invented, which enabled to generate intracoronary MRI at 1.5T and interventions under MRI guidance. In this study, we developed a 0.014-inch anti-solenoid loop coil, an alternative to the loopless coil which might be used for generating intracoronary high-resolution 3.0T MRI and interventions.
