The results of 150 placental scans are reported, using 99mTc erythrocytes, 113mIn gelatine and 113mIn tranferrin. Accuracy was checked at surgery and compared with ultra sound findings. In 62% of patients, the indications for placental scintigraphy was suspicion of placenta praevia because of bleeding in late pregnancy. In 38% placental localisation was performed for amniocentesis for Rh incompatibility. Localisation of the placenta was accomplished in 98.6% by scanning and in 95% by ultra sound. Accuracy of scanning was 94% and ultra sound 70%. Placental scanning is at present the most accurate method for a placental localisation and should therefore be used when an accurate diagnosis cannot be achieved by other techniques.
报告了使用99mTc红细胞、113mIn明胶和113mIn转铁蛋白进行的150次胎盘扫描结果。在手术中检查准确性，并与超声检查结果进行比较。62%的患者进行胎盘闪烁扫描的指征是妊娠晚期出血怀疑前置胎盘。38%的患者因Rh血型不合进行羊膜穿刺术时进行胎盘定位。通过扫描完成胎盘定位的比例为98.6%，通过超声完成的比例为95%。扫描的准确性为94%，超声为70%。目前，胎盘扫描是胎盘定位最准确的方法，因此当其他技术无法实现准确诊断时应使用该方法。
