Mammographic and magnetic resonance imaging features of breast ductal carcinoma in situ
Main Article Content
Abstract
Ductal carcinoma in situ (DCIS) is a non-invasive malignant lesion of the breast with diverse imaging manifestations, and the combination of mammography and magnetic resonance imaging (MRI) may allow a more comprehensive assessment of the lesion. This retrospective descriptive study was conducted on 56 patients diagnosed with DCIS by preoperative biopsy at Vinmec Times City International Hospital from 2021 to 2025. All patients underwent mammography and MRI before treatment; imaging features were assessed according to the Breast Imaging Reporting and Data System (BI-RADS): 67.9% had lesions detected on mammography, 65.8% had calcifications. On MRI, lesions were detected in 98.2% of cases, predominantly 85.5% presenting as non-mass enhancement. The mean lesion size by MRI was larger than by mammography, measuring 38.6 ± 22.2 mm versus 26.2 ± 19.5 mm, respectively. MRI demonstrated a high lesion detection rate in the study population, whereas mammography remained important for identifying microcalcifications.
