Whole-Heart
Magnetic Resonance Coronary Angiography (WH MRCA) is a very useful tool for
screening for coronary artery disease and usually performed during free
breathing with real time motion correction (RMC). We have developed a Motion
Correction Coefficient Pre-Analysis Method to obtain an appropriate RMC
coefficient before the WH MRCA scan and performed the feasibility study of
this method by evaluating the relation between the coefficient of RMC and the
image quality for health screening cases retrospectively. The results showed
that this method is expected to be very useful in the clinical application of
WH MRCA.
