摘要
１１９例肝血流断层显像（ＨＢＦ－ＥＣＴ）结果表明，肝血流动力学变化可分为正常（Ｎ）、迟缓（Ｄ）、脾高（Ｓ）、门脉高压（ＰＨ）、冷占位（ＣＣ）、动脉性冷和热占位（ＡＣ、ＡＷ）等七型。肝动脉指数（ＨＡＩ）、摄取指数（ＨＵＩ）、脾肝比（Ｓ／Ｌ）之总体均数差和组间均数差皆有显著意义。慢肝组为Ｄ或Ｎ型。门脉高压７８．９％为ＰＨ型，其阳性及阴性预测率为９１．８％及１００％，ＨＡＩ和Ｓ／Ｌ亦显著高于前者，肝硬变之ＨＵＩ明显减低而非肝硬变门脉高压者仍在正常范围。巨脾患者为Ｓ型，ＨＵＩ及ＨＡＩ正常。ＣＣ型诊断良性肿物准确性为８０％，ＡＣ型诊恶性肿瘤准确性为８３．６％。ＡＷ型对肝局限结节性增生具有病因特异性。
The hepatic hemodynamics were divided into seven types by the 99mTc-phytas hepatic blood flow and ECT imagings(HBF-ECT)in the 119 cases.These types included normal(N); delayed(D); splenomegaly(S); portohypertension (PH); cold-cold(CC); arterialcold(AC)and arterial-warm (AW). In each type the mean standard derivation of the hepatic arterial index(HAI),uptake index(HUI)and spleen/liver ratio(S/L)were statistically significant(P<0.001).The diagnostic postive forcast was 91.8%in the 'PH' for the portohypertension disease,all of them the HAI and S/L increased evidently,however, the HUI was reduced in the cirrhosis but normal in noncirrhosis. The 'S' only seen in splenomegaly,its HAI and HUI were normal. In the chronic hepatopathy all were'D'or'N'and its HAI was normal. The diagnostic accuracy for space taking lesion were 80%in 'C' for benign and 83.6% in 'AC' for malign. 'AW' had pathologic specifity for hepatic focal hyperplasia.
