【摘要】：目的评价二维超声、弹性成像及X线钼靶对测量乳腺肿块的大小,探寻测量乳腺肿块大小的准确方法。方法选取在我院就诊的乳腺原发实性肿块患者88例,共100个肿块,其中恶性肿块78个,良性肿块22个,所有病例均经手术病理证实。术前均用这三种方法对所有肿块大小进行测量,比较这三种方法与病理学测量的肿块最大径。并采用Pearson相关分析二维超声、弹性成像、X线钼靶与病理学测量肿块最大径的相关性。结果三种方法测量乳腺肿块最大径与病理学结果比较,均低估了乳腺肿块的实际大小。在良性组中,三种方法测得的最大径与病理学结果的相关系数差别不大(R~2=0.78、0.79、0.66);在恶性组中,弹性成像与病理学结果相关性较好,差异具有统计学意义(R~2=0.72),表明弹性成像对恶性肿块的测量更接近病理学结果。结论弹性成像在对乳腺恶性肿块大小的测定中,较二维超声及X线钼靶更准确。
[Abstract]:Objective to evaluate the accuracy of two dimensional ultrasound, elastic imaging and mammography in measuring the size of breast masses. Methods Eighty-eight patients with primary solid mass of breast were selected, including 78 malignant masses and 22 benign masses. All cases were confirmed by operation and pathology. All the tumor sizes were measured by these three methods before operation, and the maximum diameter of the masses measured by these three methods was compared with that by pathology. Pearson correlation analysis was used to analyze the correlation between the maximum diameter of the tumor and the maximum diameter of the tumor. Results compared with pathological results, the three methods underestimated the actual size of breast masses. In the benign group, the correlation coefficient between the maximum diameter measured by the three methods and the pathological results was not significantly different (RX20.780.79 / 0.66), while in the malignant group, the correlation between elastic imaging and pathological results was better. The difference was statistically significant (RV 2: 0. 72), indicating that the measurement of malignant masses by elastic imaging was closer to the pathological results. Conclusion Elastic imaging is more accurate than two-dimensional ultrasound and X-ray molybdenum target in determining the size of malignant breast masses.
