摘要
目的：应用９９ｍＴｃＥＣＤＳＰＥＣＴ断层影像采血和非采血法定量测定ｒＣＢＦ和ＣＢＦ。材料和方法：正常对照组１５例，疾病组１０例。采血法用动脉化静脉血样求得血中９９ｍＴｃＥＣＤ的浓度；非采血法用头颈平面像求得血中９９ｍＴｃＥＣＤ浓度。结果：正常对照组采血法ｒＣＢＦ２５０±４０～５９１±７６ｍｌ．ｍｉｎ－１·（１００ｇ）－１，ＣＢＦ４３０±３６ｍｌ．ｍｉｎ－１·（１００ｇ）－１；非采血法ｒＣＢＦ２６１±３２～６０３±６８ｍｌ．ｍｉｎ－１·（１００ｇ）－１，ＣＢＦ４３５±４４ｍｌ．ｍｉｎ－１·（１００ｇ）－１。和其他方法测得的正常值很接近。疾病组两法测定的结果基本一致。结论：用９９ｍＴｃ－ＥＣＤＳＰＥＣＴ断层影像测定ｒＣＢＦ和ＣＢＦ是可行的，可作为评价脑血流灌注的定量指标。
Purpose:Objective quantitation of rCBF and CBF by SPECT tomography with and without sampling blood were reported.Materials and method:15normal volunteers and 10 patients with cerebropathologies were mesuered by SIEMENS DIACAM/ICON SPECT system. 99m Tc ECD concentration in blood was determined by blood sampling or through a planar image.Results:Normal rCBF was 25 0±4 0～59 1±7 6ml.min -1 (100g) -1 ,CBF was 43 0±3 6ml.min -1 (g) -1 with blood sampling method ,and rCBF was 26.1±3 2～60.3±6 8ml.min -1 (100g) -1 without blood sampling. The patients with cerebropathologies showed samilar results in two methods.Conclution:quantification of rCBF and CBF by 99m Tc-ECD SPECT tomography was feasible for evaluating cerebral perfusion.
