MR Imaging of Coronary Arteries and Plaques.
Cardiac magnetic resonance offers the promise of radiation-free imaging of the coronary arteries, providing information with respect to luminal stenosis, plaque burden, high-risk plaque characteristics, and disease activity. In combination, this would provide a comprehensive, individualized assessment of coronary atherosclerosis that could be used to improve patient risk stratification and to g...
متن کاملReversed Spiral Imaging for Coronary MR Angiography
P. Börnert, B. Aldefeld, K. Nehrke, H. Eggers Philips Research Laboratories, Hamburg, Germany Synopsis Coronary MR angiography (CMRA) can benefit in the future from the principles of molecular imaging. Specific contrast agents will offer the opportunity to image arterial plaque directly, if appropriate image contrasts (T1 or T2*) can be introduced. Spiral imaging has been shown to be robust and...
متن کاملIntracoronary MR imaging using a 0.014-inch MR imaging-guidewire: toward MRI-guided coronary interventions.
PURPOSE To validate the feasibility of using a newly designed MR imaging-guidewire (MRIG) to guide angioplasty balloon placement in coronary arteries. MATERIALS AND METHODS A custom gold/sliver/Nitinol/MP35N-based, 0.014-inch MRIG was manufactured. To test its mechanical performance we used the new MRIG to catheterize the left coronary arteries of three dogs under x-ray fluoroscopy. To furthe...
متن کاملCoronary Embolization and Myocardial Microinfarction: MR Imaging and Histopathologic Characterization
Magnetic resonance imaging (MRI) has been proven to reliably assess regional perfusion and left ventricular (LV) function of microembolized myocardium. The visibility of microinfarct on delayed enhancement MRI (DE-MRI) is limited and dependent on technical and biological issues. Furthermore, MRI underestimates total microinfarct size compared with microscopy. MRI studies revealed that the prese...
متن کاملReproducibility of black-blood coronary vessel wall MR imaging.
PURPOSE New magnetic resonance imaging (MRI) methods can provide high spatial resolution images of the coronary artery wall, and statistically significant differences in coronary vessel wall thickness between atherosclerotic disease patients and control subjects have been shown. The aim of this study is to assess inter-study reproducibility (i.e., repeatability) of the cross-sectional 2D corona...
