乳腺癌合并细微钙化钼靶X线与彩超影像诊断对比分析

目的:观察钼靶X线与彩超对乳腺癌合并细微钙化的影像表现,比较分析两种诊断方法影像特点,指导临床对乳腺癌合并细微钙化的影像诊断。方法:回顾性分析2011年4月-2012年4月本院收治的60例经临床手术病理证实的乳腺癌合并细微钙化的患者影像学资料,分别采用钼靶X线与彩色多普勒超声两种影像诊断方法,比较两种影像诊断方法对乳腺癌合并细微钙化的准确性及影像特点。结果:钼靶X线对钙化灶的检出率为65.0%,高于彩超的35.0%,差异有统计学意义(P0.05);钼靶X线检出灵敏度为86.67%,超声成像对微小钙化检出灵敏度为46.67%。结论:钼靶X线对乳腺癌合并细微钙化的敏感度高于彩超,对早期诊断乳腺癌有较高的诊断价值,彩超可检出钼靶X线影像检出的假阴性病灶,临床可作为辅助诊断和初步筛查。

Comparative Analysis of Diagnosis of Breast Cancer with Slight Calcification by Mammography and Color Doppler Ultrasound Imaging

Objective：To observe the imaging manifestations of mammography and color doppler ultrasound for breast ca with slight calcification, comparative analysis of imaging characteristics of two diagnosis methods,to guide the clinical imaging diagnosis of breast cancer with slight calcification. Method：Retrospectively analyzed the clinical imaging data of 60 patients in our hospital from April 2011 to April 2012,which were surgical pathologic proved breast cancer with slight calcification. Respectively used mammography and color doppler ultrasound,compared the accuracy and image features of two image diagnosis method for breast cancer with slight calcification. Result：The microcalcification detection rate of molybdenum target X-ray was 65.0%,higher than color doppler ultrasound detection rate（35.0%）,difference was statistically significant（P〈0.05）;Detection sensitivity rate of molybdenum target X-ray was 86.67%,slight calcification detection sensitivity of ultrasonic imaging was 46.67%. Conclusion：The sensitivity of molybdenum target X-ray to breast cancer with small calcification is higher than color doppler ultrasound,has high diagnostic value for early diagnosis of breast cancer,color doppler ultrasound can check out molybdenum target X-ray detection of false negatives lesions,can be used as an initial screening and diagnosis in the clinical.
