The
combined Whole-heart coronary MRA and black-blood-coronary-wall-imaging
hasnt been reported to detect CAD yet. Continuous slices for wall imaging of
48 segments were positioned along the suspected lesions of WH CMRA. A
positive diagnosis of CAD was made when stenosis 50% at least one of the
techniques. 15/48 segments were diagnosed as CAD by x-ray angiography. The
sensitivities of WH CMRA only and both techniques were (12/15) and (14/15),
NPVs were (33/36) and (33/34), respectively. There was no difference in
specificity or PPV. The combination of two techniques improves the diagnostic
accuracy to detect CAD over WH CMRA alone.
