Summary

Dynamic 99mTc-Tetrofosmin CZT-SPECT myocardial perfusion imaging (MPI) is an advanced functional imaging technique giving important myocardial flow quantification added data in comparison with conventional MPI, especially in coronary multi vessel disease. A large-scale validation of diagnostic performances of myocardial flow reserve (MFR) estimated with Dynamic 99mTc-Tetrofosmin CZT-SPECT MPI would allow a non-invasive approach instead of invasive intra-coronary fractional flow reserve (FFR) measurement. The aim of this prospective study is to assess diagnostic performances of MFR calculated with dynamic 99mTc-Tetrofosmin CZT-SPECT MPI in comparison with invasive intra-coronary FFR measurement in patients with significant residual coronary arteries stenosis after acute coronary syndrome .
