Some PET radiopharmaceuticals demonstrate good breast tumor targeting capabilities (FDG).
PEM is a possibly more effective method for detecting some suspicious breast lesions compared to mammography.
Method for acquiring biopsy samples from suspicious lesions is needed.
Imaging Time Test
Images showing the ability to discern smaller lesions depending on acquisition time.
Gelatin Breast Phantom Images
Phantom made from food gelatin and radioactive lesions.
PEM detectors successfully intergrated into a Lorad biopsy system.
PEM system had sufficient capabilities to detect small (5mm diameter) simulated breast lesion.
Stereotactic coordinate algorithm demonstrated very good accuracy and precision in calculating the 3-D positions of point sources.
