Autoradiographic enhancement of mammograms. Investigation of a new dose reduction technique

Autoradiographic image enhancement using thiourea labeled with 35S was investigated as a means of reducing dose in mammography. It was found that mammograms underexposed as much as tenfold can be autoradiographically intensified so that the enhanced image is comparable with a normal exposure. Limitations to routine use include cost, processing time, and disposal of radioactive solutions.
