Figure 4: Abnormal MPI in the vertical long-axis slices of a representative patient. Both 99mTc-N-DBODC5 (a) and 99mTc-MIBI (b) images demonstrate an inferoposterior defect (white arrows). The defect is well visualized on two tracer images corresponding to the CA result. This coronary angiography (c) detected a stenosis of 90% in the RCA. The concordance for diagnosis of myocardial ischemia was seen on 99mTc-N-DBODC5 and 99mTc-MIBI studies.
