Simultaneous MR/PET scanners allow for the exploration of novel partial volume effect correction techniques. We report here the first attempt to apply these methods to simultaneous MR/PET imaging of the carotid arteries. The current study shows a comparison of the effects on quantitative PET of a wavelet-based partial volume effect correction technique for use in carotid MR/PET protocols. The wavelet-based technique is designed to compensate for partial volume artifacts such as tissue fraction effects. The technique applied here demonstrated an improvement in both resolution and quantification in the phantom and the in the carotid arteries of the patient.
