We have developed a 3DPR based contrast-enhanced
coronary MRA technique that delivers good image quality
at (1.0 mm)
3
spatial
resolution with scan time of 5 minutes. Further
investigations are warranted on subjective image quality
evaluation, protocol optimization, and tests on patient
population with suspected CAD.
