34.03 Comparison of attenuation correction in myocardial SPECT using Gadolinium-153 line sources or low-dose CT

Single-Photon Emission Computed Tomography/Computed Tomography: Basic Instrumentation and Innovations

“…Although no extensive large scale clinical studies have been reported on the value of SPECT/CT devices in attenuation correction, preliminary studies in patients have reported some discrepancies between attenuation compensated myocardial perfusion studies using CT and Gd-153 transmission sources and have highlighted the problems of noise and mis-registration between the CT and SPECT images that are discussed above.
