This article describes the characteristics of ultrasound images of DCIS based on the BC-02 study conducted by The Japanese Association of Breast and Thyroid Sonology (JABTS). In the BC-02 study, ultrasound images of 705 DCIS cases were classified by imaging findings. The results showed that non-mass abnormalities accounted for 60% of all lesions and masses for 40%. Looking at each subclassification, hypoechoic areas in the mammary gland were the most common (50% of the total), followed by solid masses (31%), mixed masses (9%), and abnormalities of the ducts (8%). These four classifications accounted for 98% of the total. Echogenic foci without a hypoechoic area, architectural distortion, and clustered microcysts were very rare, accounting for about 1% of the total. The ultrasound images of DCIS were characterized by a wide range of variations from masses to non-masses abnormalities, with hypoechoic areas in the mammary gland being the most common, followed by solid masses.<\/jats:p>","DOI":"10.1007\/s10396-023-01334-7","type":"journal-article","created":{"date-parts":[[2023,6,28]],"date-time":"2023-06-28T03:30:57Z","timestamp":1687923057000},"page":"347-350","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Features of ductal carcinoma in situ ultrasound images"],"prefix":"10.1007","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8375-7161","authenticated-orcid":false,"given":"Takanori","family":"Watanabe","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,6,28]]},"reference":[{"key":"1334_CR1","volume-title":"Guidelines for breast ultrasound: Management and diagnosis","author":"Japan Association of Breast and Thyroid Sonology (JABTS)","year":"2003","unstructured":"Japan Association of Breast and Thyroid Sonology (JABTS).
