SPECTCT双时相99mTc-MIBI断层显像在乳腺癌诊断中的应用摘要：目的探讨spect/ct双时相99mtc-mibi断层显像在乳腺癌临床中的诊断价值。方法选取2015年1月～2017年5月广西柳州市中医院胸外科收治的女性乳腺疾病患者98例进行了术前两种检查方法的诊断，并将诊断结果记录，与术后的病理结果进行比对。结果spect/ct双时相99mtc-mibi断层显像的敏感性94.80%、特异性90.00%、准确性93.90%，高于钼靶x线检查的敏感性82.10%、特异性60.00%、准确性77.60%，spect/ct双时相99mtc-mibi断层显像和钼靶x线检查对腋窝淋巴结转移灶的检出率分别为84.30%和59.40%，两种检查方法对乳腺癌的诊断比较均有统计学差异（p关键词：乳腺癌;spect/ct;99mtc-mibi断层显像;钼靶x线：r817.4文献标识码：adoi：10.3969/j.issn.1006-1959.2018.05.053：1006-1959（2018）05-0147-03applicationofspect/ctdual-phase99mtc-mibitomographyinthediagnosisofbreastcancerdongyun（departmentofnuclearmedicine，liuzhouchinesemedicinehospital，liuzhou545001，guangxi，china）abstract：objectivetoevaluatethediagnosticvalueofspect/ctdual-phase99mtc-mibitomographyinbreastcancer.methodsatotalof98womenwithbreastdiseasesadmittedindepartmentofthoracicsurgery，liuzhouhospitaloftraditionalchinesemedicineinjanuary2015～2017may，wereselectedforthediagnosisoftwokindsofexaminationmethodsbeforeoperation，andthediagnosisresultswerecomparedwithpostoperativepathologicalresults.theresultsofthetwodiagnosticmethodswerecompared.resultsspect/ct99mtc-mibidoublephaseimagingsensitivityof94.80%，specificityof90.00%，accuracyof93.90%，higherthanmammographysensitivity82.10%，specificity60.00%，accuracy77.60%，spect/ct99mtc-mibidoublephaseimagingandmammographynodemetastasisdetectionrateswere84.30%and59.40%ofaxillarylymph，twomethodsindiagnosisofbreastcancerwerestatisticallysignificant（p0.05）.conclusion99mtc-mibidoublephasetomographyissuperiortomammographyindiagnosisofbreastcancer，andhashighpracticalvalue.keywords：breastcancer;spect/ct;99mtc-mibitomography;molybdenumtargetx-ray
