摘　　要：目的:探讨单光发射型计算机断层(single-photo emission computed tomography)血池显像诊断颌面部脉管畸形的价值。方法:对40例临床上怀疑颌面部脉管畸形患者进行颌面部核素扫描,分别进行SPECT血池显像,以^(99)Tc^m-RBC为显像剂,观察不同类型脉管畸形血池显像情况,诊断结果与MRI比较进行χ~2检验。结果:^(99)Tc^m-RBC血池显像对颌面部静脉畸形诊断敏感度、特异性、准确性分别是97.50%%、100.00%、100.00%。^(99)Tc^m-RBC血池显像40例患者其中39例阳性(97.50%,39/40);1例显示假阴性(2.50%,1/40);MRI对颌面部静脉畸形诊断其中33例阳性(82.50%,33/40),7例为阴性(7.50%,7/40),^(99)Tc^m-RBC血池显像与MRI影像学对比检查经χ~2检验有统计学意义(χ~2=0.028,P<0.05)。不同类型脉管畸形血池显像出现在不同时相。结论:^(99)Tc^m-RBC血池显像诊断颌面部脉管畸形有良好的应用价值。Objective:To evaluate the application of 99 Tc m-RBC blood pool scintigraphy in diagnosis of maxillofacial vascular malformations.Methods:Forty patients with clinically suspected maxillofacial vein malformations were examined by 99 Tc m-RBC blood pool scintigraphy and the results were compared with MRI.The chi-square test was used to compare the significance.Results:The sensitivity,specificity,and accuracy of 99 Tc m-RBC blood pool scintigraphy in diagnosis of maxillofacial vein malformations were 97.50%,100.00%,and 100.00%,respectively.Thirty-nine of 40 patients who had maxillofacial vein malformations showed positive images(97.50%),and 1 patients showed false positive images(2.50%);33 of 40 patients by MRI who had malignant tumors showed positive image(82.50%),and 7 patients showed negative image(7.50%).There was a significant difference between two groups by the chi-squre test(P<0.05).Conclusion:It is suggested that 9Tcm-RBC blood pool scintigraphy can be used in diagnosis of maxillofacial vein malformations.
