Accurate radiotracer quantification in nuclear projection imaging requires both attenuation and background corrections. In this study, we acquired MR and nuclear projection images of a phantom using a novel MR-SPECT system. The MRI was then used to facilitate correction of the nuclear projection data. The results demonstrate improved accuracy for radiotracer quantification using data acquired from simultaneous imaging.
