Abstract :
Reports on the use of a microchannel plate-based imaging system for autoradiography of biological samples labeled with radionuclides emitting high-energy (140-2000 keV) beta particle and gamma radiation. Samples can be imaged sufficiently rapidly (exposures 1-2 hours for electrophoresis gels, ~24 hours for thin tissue sections) to allow imaging of nuclides with short half-lives, such as 99mTc. Measurement of the detector efficiencies for 99mTc and 188Re isotopes is reported. Images of a variety of samples labeled with clinically important therapeutic radionuclides, 67 Cu and 131I are presented. In particular the authors report preliminary images of radiolabeled anti-MUCI mucin antibody C595 currently being developed as a therapeutic conjugate for treating bladder, breast and ovarian tumours
