Abstract:
A method for detecting radiopharmaceuticals within diseased tissue, comprising:a) providing:1) a patient having a region of diseased tissue,2) a radiopharmaceutical capable of emitting beta particles, and3) a device comprising a housing having a rear portion and a front portion, said front portion comprising a tip with first and second radiation detectors disposed within said housing at said tip, said first detector capable of detecting beta particles and gamma radiation and serving to shield said second detector from at least a portion of the beta particles detected by said first detector, wherein said first detector is positioned in front of said second detector in a manner such that radiation reaching said tip of said device contacts said first detector prior to contacting said second detector;b) administering said radiopharmaceutical to said patient; andc) detecting beta particles emitted from said radiopharmaceutical with said device within said region of said patient.
