In a patient with third trimester abdominal pregnancy with fetal demise, technetium-99m-labeled erythrocytes (99mTc-RBCs) localized the placenta preoperatively, after nonvisualization by ultrasonography and arteriography. Extrauterine placental localization by blood-pool imaging may be useful when ultrasound fails.
在一名孕晚期腹部妊娠且胎儿死亡的患者中，在超声检查和动脉造影未显示胎盘的情况下，术前用99m锝标记红细胞（99mTc-RBCs）定位了胎盘。当超声检查失败时，通过血池成像进行宫外胎盘定位可能会有所帮助。
