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.
PEM-Biopsy System
|
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. |
