Introduction: Tc-99m macro aggregated albumin (MAA) is synonymous for lung perfusion scintigraphy and is part of the study in the evaluation of pulmonary thromboembolism. We wanted to highlight the utilities of Tc-99m MAA other than pulmonary embolism as a pictorial assay. Materials and Methods...
方法 经皮下埋藏式输注泵注入 99m Tc-MAA 灌注显像检测32例晚期肝癌患者.结果 显示导管位 置合适者28例,T/N 为3.36(0.97~10.67),PSI为7 .25% (3.54% ~43 .39%),肺分流指数在 5% 以下占 53.6% (15/28),5%~15%占28.6%(8/28),15%以上17.8%(5/28).结论 99m Tc-MAA 灌注显像可以准确测定 T...
目的部分肝肿瘤患者存在肝肺血管通路.对于此类病人在进行90Y放射粒子治疗时会发生一些并发症.所以术前充分评估肝肺血管通路的程度,成为该项治疗必不可少的前提.方法 23例肝肿瘤病人(原发肝癌7例,转移性肝癌16例,其中男14例,女9例, 平均年龄56岁)经肝动脉向肝内注入99mTc-MAA 3mCi,15分钟后进行前位和后位的...
Vena caval filters were inserted and thrombolysis were given in patients with big area APE and/or iliofemoral vein thrombosis indicated by (superscript 99m)Tc-MAA imaging. Thrombolysis was given in patients with small area APE and/or subpopliteal vein thrombosis. PPI was reexamined after 2~4 ...
