Liver scanning with 99mCi 99Tc sulphur-colloid was practiced in 50 patients: 30 suffering from malignant tumors, 10 from hepatic cirrhosis and 10 from pyrexia of unknown origin. Liver radioactivity was recorded by a gamma-camera connected to a computer, 1 frame each 10 seconds for 15 minutes. The spectral analysis of the radioactivity counts taken in different region of interest, showed evidence of a periodic fluctuation, with a period value around 1 minute. Comparative ultrasonographic dynamic study showed evidence of the same phenomena in 16 examined patients. The period of pulsation was found different in each of the following groups: normal liver, cirrhotic, metastatic and infectious diseases.
对50例患者进行了用99mCi 99锝硫胶体进行肝脏扫描：30例患有恶性肿瘤，10例患有肝硬化，10例患有不明原因发热。通过连接计算机的伽马相机记录肝脏放射性，每10秒采集1帧，共采集15分钟。对在不同感兴趣区域采集的放射性计数进行频谱分析，显示有周期性波动的证据，周期值约为1分钟。比较超声动态研究显示，在16例接受检查的患者中也有相同现象的证据。发现搏动周期在以下各组中各不相同：正常肝脏、肝硬化、转移性疾病和感染性疾病。
