Gated SPECT acquisitions have been the mainstay of nuclear cardiac imaging for the last two decades, serving as a non-invasive way to image perfusion and wall motion. There have been small incremental improvements in quantitative software over the years, but new applications that provide clinicians with more and different diagnostic information simply have not been available, until now.
D-SPECT’s unique implementation of CZT and reconstruction software lays the foundation for dynamic SPECT acquisitions. The D-SPECT rapidly images the bolus injection of 99mTc-Sestamibi as it passes through the left ventricle of the heart.
Once the appropriate cycles are rebinned/reconstructed, the D-SPECT quantitative software package analyzes the bolus and extraction of the radiopharmaceutical by the myocardium in the left ventricle to calculate the Coronary Flow Reserve (CFR) by coronary artery.
