Abstract

A comparison is presented of the image quality obtained with a 70 mm Ge(Li) detector scanner and with routine techniques based on NaI (Tl) detectors. One hundred and sixty-five pairs of brain scans have been examined for which the patients have been scanned with both Ge(Li) and NaI (Tl) detectors. It is concluded that no major difficulties exist in introducing Ge(Li) scanners and that while a comparison of scans from different instruments is difficult there is evidence that improved diagnostic information may be obtained from scanners with Ge(Li) detectors.

摘要

本文对使用70毫米锗（锂）探测器扫描仪和基于碘化钠（铊）探测器的常规技术所获得的图像质量进行了比较。对165对脑部扫描进行了检查，这些患者同时使用锗（锂）探测器和碘化钠（铊）探测器进行了扫描。得出的结论是，引入锗（锂）扫描仪不存在重大困难，虽然比较不同仪器的扫描图像很困难，但有证据表明，使用锗（锂）探测器的扫描仪可能会获得更好的诊断信息。
