SPECT/CT is a highly sensitive and specific diagnostic tool for pulmonary embolism assessment. It is a low dose alternative to CTPA with no contrast related complications and is more accurate than planar VQ studies. With SPECT/CT, we can reduce the overall radiation dose by 80 percent and up to 96 percent for breast tissue, when compared to a CTPA. Additionally, hybrid imaging increases the sensitivity to 97 percent and specificity to 100 percent. With Q.Lung, you can now accurately display both ventilation and perfusion in an easily interpretable review screen, integrated with the lung atlas, which can be customized to your reading preferences. It also helps to easily identify uptake mismatches and automatically calculates its quotient for a more effective way to diagnose pulmonary embolism.
