Myocardial perfusion imaging in overweight patients and women: Is it CZT good enough?

Review of cardiovascular imaging in the Journal of Nuclear Cardiology 2020: positron emission tomography, computed tomography, and magnetic resonance

“…29 While attenuation correction and MBF calculation were performed with 82Rb-PET, neither of them was used with SPECT imaging despite the fact that CZT camera has robust attenuation correction and the capability to quantify MBF. 30 Although cardiac PET imaging provides high diagnostic quality imaging and outperforms SPECT, it remains susceptible to artifact with room for optimization. In particular, increased gastric activity which is seen in 10% of 82Rb-PET MPI often causes inferior attenuation artifact and in extreme cases may lead to inconclusive studies.…”
