CT钼靶X线对乳腺癌早期发现的价值研究

Study of the Early Detection Value of CT and Mammography for Breast Cancer

目的探讨CT检查结合钼靶X线检查对乳腺癌早期发现的临床价值。方法手术并经病理检查证实为乳腺癌的80例患者,术前均行CT和钼靶X线检查,回顾性分析其影像学及病理学资料。结果单纯钼靶X线检查检出乳腺癌64例(80.0%),单纯CT检查检出乳腺癌72例(90.0%),CT与钼靶X线联合检查检出乳腺癌77例(96.3%),3种方法检出乳腺癌的诊断符合率及误诊率比较差异有统计学意义(P<0.05)。单纯CT发现钙化45例(56.3%),单纯钼靶X线发现钙化63例(78.8%),CT与钼靶X线对钙化灶检出率比较差异有统计学意义(P<0.05)。单纯CT发现腋窝淋巴结转移49例(89.1%),单纯钼靶X线发现腋窝淋巴结转移40例(72.7%)。CT与钼靶X线淋巴结转移检出率比较差异有统计学意义(P<0.05)。结论 CT结合钼靶X线检查能够明显提高乳腺癌的早期诊断率。

Objective To investigate the clinical value of CT and mammography in early detection of breast cancer . Methods 80 patients confirmed to be breast cancer through pathological examination received CT and mammography before the operation.The radiological and pathological material were retrospectively analyzed .Results The positive detection rates of single mammography and single CT were 80.0%(64/80) and 90.0%(72/80),respectively.The positive detection rate of combined examination was 96.3%(77/80),and the difference in positive detection rate and misdiagnosis rate among these 3 methods were significant (P<0.05).The detection rates of calcification of single CT and single mammography were 56.3% (45/80) and 78.8%(63/80),respectively,and the difference was significant (P<0.05).The detection rates of axillary lymph metastases of single CT and single mammography were 89.1%(49/55) and 72.7%(40/55),respectively,and the difference was significant (P<0.05).Conclusion Mammography combined with CT can improve early detection rate of breast cancer .
