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.
