应用单光子发射型计算机断层显像系统（ｓｉｎｇｌｅｐｈｏｔｏｎｅｍｉｓｓｉｏｎｃｏｍｐｕｔｅｄｔｏｍｏｇｒａｐｈｙ，ＳＰＥＣＴ）对不同容量反复２次部分肝切除后大鼠肝脏体积及肝血流量作动态测定。结果表明：首次切肝量较小的大鼠对反复部分肝切除耐受性较好，Ａ组２次肝切除术后肝再生速率明显优于Ｂ、Ｃ组（Ｐ＜０．０１）。ＳＰＥＣＴ具有测量准确、重复性好、无创伤、可定量的特点。
Single photon emission computed tomography (SPECT) was used to measure the liver volume and hepatic blood flow in rats after repeated partial hepatectomy with different volumes. The results showed that the rats with the first small amount of hepatectomy were better tolerant to repeated partial hepatectomy. The rate of liver regeneration after two hepatectomy in group A was significantly better than that in group B and C (P <0.01). SPECT with accurate measurement, good repeatability, non-invasive, quantitative features.
