点压X线放大摄影技术在乳腺微小病变中的应用

Application of Magnification Mammography in Breast Micro-lesion

目的:探讨点压X线放大摄影技术在乳腺微小病变中的应用价值。方法:通过对68例钼靶X线行常规CC位和MLO位,并辅以点压X线放大摄影技术对临床可扪及肿块但影像结构紊乱以及单纯钙化不能扪及肿块的乳腺进行良恶性鉴别。结果:68例患者行常规CC位及MLO位摄片,有11例能明确影像学诊断,病灶检出率为16.2%,其中良性诊断4例,恶性诊断7例;经点压X线放大摄影后,68例患者中有59例能明确影像学诊断,病灶检出率为86.8%,其中良性诊断32例,恶性诊断27例,卡方检验结果证明,点压X线放大摄影检出率显著高于常规摄片检出率(P<0.01)。结论:在乳腺X线摄影中应用点压X线放大摄影,可对常规CC位和MLO位未能清楚显示的微小钙化和细微伴随征象进行观察,能够提高微小病变的检出率,利于良恶性肿瘤的鉴别诊断,减少乳腺癌的漏诊,增加诊断的准确性,具有重要临床指导意义。

Objective：To assess the application of magnification mammography in breast micro-lesion. Methods：68 cases with breast lesions underwent conventional mammography and magnification mammography. The breast lesions included massess with architecture distortion and breast calcification without mass. Images were compared and differention was made between benign and malignant lesions. Results： Among the 68 cases by conventional mammography check, 6 were judged as benign, 7 as malignant and the remaining 57 unsure. When reexamined by magnification mammography, 32 were shown to be benign,27 to be malignant and the remaining 9 still unsure. Conclusive pathological exam after open biopsy showed that 36 cases were malignant and 32 cases were benign. The accuracy rate of diagnosis in 68 cases with micro-lesion findings under- going the magnification mammography was greater than that in cases undergoing the conventional mammography. Conclu- sion：Magnification mammography used in mammography diagnosis can obuiously improve the diagnosis accuracy rate of the breast cancer. It plays an important role in clinical diagnosis.
