At Brookhaven National Laboratory, we are developing a MRI compatible dedicated breast PET scanner that will enable simultaneous PET-MRI imaging of the breast. We have developed and tested a prototype version of the PET system that has an average resolution less than 2 mm FWHM. Good quality MRI images were obtained with the PET system operating unshielded inside the field of view of a 1.5 T dedicated breast MRI. Our next goal is to acquire simultaneous PET-MRI images using the prototype PET and dedicated breast MRI system.
