Abstract
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.
摘要
研究了使用用35S标记的硫脲进行放射自显影图像增强，作为降低乳腺X线摄影剂量的一种方法。结果发现，曝光不足多达十倍的乳腺X线照片可以通过放射自显影进行增强，从而使增强后的图像与正常曝光的图像相当。常规使用的限制包括成本、处理时间以及放射性溶液的处理。
