Reversed Spiral Imaging for Coronary MR Angiography

P. Bornert, 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 efficient for CMRA, and reversed spiral imaging can generate strong T2* weighting. In this work, the applicability of free breathing, submillimeter 2D and 3D reversed spiral coronary MRA with strong T2* contrast was studied in the view of future contrast agent developments.
