title: Semiquantitative 67Ga scanning of lung cancer by scintiscoring: its usefulness in diagnosis of localization, therapeutic effectiveness, radiation pneumo-mediastinitis and recurrence.
abstract: Attempts were made to attain a semiquantitative evaluation of therapeutic effectiveness of lung cancer by scintiscoring of the liver as well as the tumor lesion. A relative counting ratio of tumor to liver was computed, and this was found useful: in areas of active tumorous growth, higher ratios were obtained. The ratios returned to the control levels following irradiation with or without an anti-inflammatory regimen including prednine. The technic is simple, and yet invaluable especially when the tumor locates in the mediastinum escaping from radiological detection. Satisfactorily frequent repetition would be competent enough in early diagnosis of developing radiation pneumo-mediastinitis and regrowths in the mediastinum and fibrotic abnormal shadows as well. The principle would be best rewarded by use of a whole-body scanner equipped with a digital computer.
