摘要
目的 探讨99mTc MAA灌注显像用于测定T/N(瘤 /非瘤肝组织摄取比值 )和PSI(肺分流指数 )的应用价值。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 2 8例 ,T/N为 3 .36 (0 .97~ 10 .6 7) ,PSI为 7.2 5 % (3.5 4%~ 43 .39% ) ,肺分流指数在 5 %以下占 5 3.6 %(15 / 2 8) ,5 %~ 15 %占 2 8.6 % (8/ 2 8) ,15 %以上 17.8% (5 / 2 8)。结论 99m Tc MAA灌注显像可以准确测定T/N和PSI,对指导晚期肝癌治疗有较好的临床应用价值。
PurposeTo evaluate the 99m Tc MAA infusion images in the diagnosis of hepatoccllular csrcinoma (HCC) patients by their blood supply,T/N rates(the absorbrate between tumor tissues and non tumor tissues) and PSI(pulmonary diffluence index). Methods32 patients with later hepatocellular carcinoma (HCC)received administration of 99m Tc MAA into hepatic artery by hypodermic pump. Results 99m Tc MAA infusion images show that 28 patients have catheter in suitable positions,lung visualized slightly in 13 of them. 99m Tc MAA infusion images show collapsed or misplaced catheters in 4 patients,catheter occluded in one patients.T/N is 3.36(0.97~10.67),PSI is 7 .25% (3.54%~43 .39%),pulmonary diffluence index below 5% is 53.6 %(15/28),5%~15% is 28.6%(8/28),over 15% is 17.8%(5/28).Concousion 99m Tc MAA infusion image is a simple and convenient operation that can evaluate the blood supply of liver tumor and measure T/N and PSI.It has great clinical value in choice and instruction of the therapy in HCC patients .
