Objective To evaluate the value of conventional ultrasound(US),contrast-enhanced ultrasound(CEUS)and dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in the evaluation of breast invasive ductal carcino-mas.Methods A retrospective case-control study was used to analyze the case data of 79 patients with suspected invasive ductal carcinoma of breast admitted to our hospital from October 2020 to February 2023.All patients underwent routine US,CEUS and DCE-MRI examinations before surgery.The gold standard was the results of surgical pathologic cytology.Com-pared with the conventional US,CEUS and DCE-MRI in the detection of breast invasive ductal carcinoma,the diagnostic ef-ficiency and the accuracy of lesion size and maximum diameter difference were compared with the gold standard.Results Compared with the results of operation and pathological biopsy,67 cases of breast infiltrating ductal carcinoma were detected by routine US.The detection rate was 67/71(94.37%),69 cases of breast invasive ductal carcinoma were detected by CEUS.The detection rate was 69/71(97.18%).DCE-MRI detected 70 cases of breast infiltrating ductal carcinoma.The detection rate was 70/71(98.59%).Compared with the results of surgical pathological biopsy,the maximum lesion diame-ter detected by routine US was smaller than that by surgical pathological biopsy(P<0.05),and the maximum lesion diam-eter detected by CEUS was larger than that by surgical pathological biopsy(P>0.05).The maximum lesion diameter de-tected by DCE-MRI was similar to the results of surgical pathological biopsy,but there was no significant difference between groups(P>0.05).The underestimation rate of lesions measured by conventional US was higher than that measured by CEUS and DCE-MRI(P<0.05),and the overestimation rate of lesions measured by conventional US was lower than that measured by CEUS and DCE-MRI,but there was no significant difference between groups(P>0.05).Conclusion Con-ventional US,CEUS and DCE-MRI can all diagnose breast infiltrating ductal carcinoma,but the maximum diameter of the lesions measured by conventional US is likely to be underestimated,while the maximum diameter of the lesions measured by CEUS and DCE-MRI is likely to be overestimated.Therefore,appropriate examination methods should be selected according to specific clinical conditions.
