Accurate SPECT imaging requires attenuation correction (AC) of the nuclear projection data. In this study, we simultaneously acquired SPECT and MRI data of a simple cylindrical phantom using a novel MR-SPECT system. This MRI data was then used to perform the AC of the SPECT data. The results demonstrate the feasibility of performing AC using data acquired from simultaneous MR and SPECT imaging.
