【摘要】：目的比较全数字化乳腺摄影(FFDM)与数字化乳腺断层摄影(DBT)评估乳腺导管原位癌(DCIS)大小的准确率。方法分析30例病理确诊为乳腺DCIS的女性患者,由2名放射科医师在FFDM、DBT图像上测量病灶的大小,并与病理结果作对比。采用Pearson相关分析比较两种检查方法与病理结果的相关性。结果医师1和医师2的FFDM测量结果与病理结果呈正相关性(r=0.857、0.818,P均0.01),医师1和医师2的DBT测量结果与病理结果呈正相关(r=0.924、0.885,P均0.01);2名医师采用FFDM和DBT测量结果的组内相关系数(ICC)分别为0.947、0.908。结论FFDM、DBT均能较好评估乳腺DCIS大小,且与FFDM相比,DBT能更准确评估病灶的大小。2名医师对于病灶大小评估具有较高的一致性。对于存在钙化的DCIS,FFDM、DBT对于病灶的测量均小于病理测量结果,故临床手术可能需要切除更大的范围。
[Abstract]:Objective to compare the accuracy of full digital mammography (FDM) and digital mammography (DBT) in assessing the size of breast ductal carcinoma in situ. The size of the lesions was measured by two radiologists on FFDMU DBT images. Pearson correlation analysis was used to compare the correlation between the two examination methods and pathological results. Results the FFDM measurement results of physician 1 and physician 2 were positively correlated with pathological results (P = 0. 01, P = 0. 01, P = 0. 01, P = 0. 01, P = 0. 01, P = 0. 01, P = 0. 01, P = 0. 01, P = 0. 01, respectively). There was a positive correlation between the results of DBT measurement and pathological results. The correlation coefficients of FFDM and DBT were 0.947 and 0.9080.Conclusion the DCIS size of mammary gland can be evaluated well by FFDM. Compared with FFDM, the diameter of lesions was more accurately assessed by 2 physicians than that by FFDM, and the measurement of lesions in DCIS FFDMDBT with calcification was smaller than that of pathological measurements. Therefore, clinical surgery may require a wider range of excision.
