摘    要:目的:评价GS Quant软件结合99mTc-甲氧基异TN(MtBI)门控心肌断层显像(G-SPECT)测定左室射血分数(LVEF)的价值。方法:选择24例于同期2周内完成G-SPECT、门控心血池显像(RNA)和超声心动图检查(UCG)的患者,比较3种方法所测定的LVEF值。结果:99mTc-MIBI G-SPECT所测得的LVEF值与RNA和UCG法所测得的LVEF值均有较好的相关性,相关系数r分别为0.81(P<0.05)和0.76(P<0.05)。结论:99mTc-MIBI G-SPECT所测定的LVEF值有很好的准确性和可重复性,具有较高的临床应用价值,可进一步推广应用门控核素心肌断层显像这一技术。

Abstract:To investigate the value of left ventricular ejection fraction(LVEF) measured by 99mTc-MIBI gated myocardial perfusion single photon emission computed tomography (G-SPECT) with the software GS Quant. Methods: The values of LVEF measured by three methods were calculated and compared in twenty-four patients who had undergone 99mTc-MIBI gated myocardial SPECT, gated radionuclide angiocardiography and echocardiography within two weeks. Results: The value of LVEF from 99mTc-MIBI gated myocardial perfusion SPECT has an excellent positive correlation with those from gated radionuclide angiocardiography and echocardiography ( r = 0. 81, P < 0. 05; r = 0. 76, P < 0. 05, respectively). Conclusion: LVEF can be accurately assessed by 99mTc-MIBI gated myocardial SPECT with a good reproducibility. These results support a further clinical application of gated myocardial perfusion SPECT.
Keywords:gated myocardial perfusion SPECT  left ventricular ejection fraction  radionuclide  angiocardiography  echocardiogra-phy  99mTc-MIBI
