Objective To investigate the correlation between conventional two-dimensional ultrasonographic features of ductal carcinoma in situ (DCIS) of the blast and its combined elastic (UE) and clinical developmental. Methods From April 2016 to April 2019,138patients with DCIS confirmed by operation and pathology were enrolled in this study. All patients underwent route two-dimensional ultrasound examination. The ul traditional practices of DCIS (including the presentation or observation of masses, certification and ul traditional typing), elastic hardness score and its relationship with pathological grading were analyzed. Results Among 138patients, 78 were mass type, 60 were non-mass type, 97 were calcified type and 41were non-calcified type. UE score showed that none of 138DCIS patients had 1and 2scores.The elastic hardness scores of lump with calcification type, lump without calcification type, non-lump with calcification type, non-lump with calcification type and non-lump with calcification type were 3.04%, 36.73%, 61.22% and 10.34%, 55.17%, 34.48 per and 4.17%, 39.58%, and 25.00%,56.25 per cent and 33.33%,41.67 per cent respectively. The differences in elastic hardness scores of the four ultrasound types were statistically significant (P <0.05). The low, medium and high levels of tumor group and non-tumor group were 34.52%, 32.05%, 33.33%, 6.67%, 40.00 and 53.33%, and 53.33%, respectively, with statistically significant differences (P <0.05). The low, medium and high levels of calcification group and non-calcification group were 14.43%, 39.18%, 46.39%, 41.46%, 26.83% and 31.71%, respectively. The differences between the two groups were statistically significant (P <0.05). There were 14.29%, 36.73%, and 34.48%,48.98 per cent 44.83%, and 16.67%,20.69 per cent 33.33%, 50.00 and 50.00%, 16.67% and 33.33%of low, medium and high grades of mass with calcification, mass without calcification, non-mass with calcification and non-mass with calcification, respectively (P <0.05). The elastic hardness scores of low, middle and high grades were 55.56%, 11.11%, 33.33 and 34.48%,33.33 39.66%, and 8.45%,25.86 per cent 35.21% and 56.34%, respectively, with significant differences (P <0.05). Conclusion DCIS conventional two-dimensional ultrasonography and elastography are significantly correlated with clinicopathological grading.
