WebSep 4, 2024 · Citation, DOI, disclosures and article data. A focus in the context of breast MRI using the BI-RADS lexicon refers to a unique enhancing dot that is too small to characterize further morphologically as a mass or nonmass enhancement. Usually, a focus is smaller than 5 mm. WebMRI is a powerful tool: it is able to detect cancer not visible on conventional imaging, it can be used as a problem-solving instrument, and it can be applied to screen high-risk patients. Breast MRI is also better at monitoring the response to chemotherapy than other …
