Data are presented as number (%); MIBI = 99mTc-MIBI, DBODC = 99mTc-N-DBODC5; LAD: left anterior descending coronary artery; LCX: left circumflex coronary artery; RCA: right coronary artery. CA was used as the “gold standard” for the calculation of the , which is determine between SPECT MPI and CA. If there is no agreement, = 0.20–0.39; moderate agreement, = 0.40–0.59; very good agreement, = 0.60–0.79; excellent agreement, = 0.80–1.00.
