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.
