Characteristics and Pathologic Results of Foci on Breast Magnetic Resonance Imaging: A Systematic Review and Meta-Analysis.

ABSTRACT:

Background

Although T2-weighted imaging (T2WI) hypointensity, delayed enhancement washout pattern, interval growth, and new appearance of a focus have been associated with malignancy, the results are not consistent.

Purpose

To investigate the malignancy rate and identify the clinical and imaging characteristics associated with malignancy among foci in breast MRI.

Study type

Meta-analysis.

Subjects

32 articles with 2645 foci.

Field strength/sequence

1.5 T and 3.0 T. T1WI, T2WI, and DCE-MRI.

Assessment

PubMed, Embase, Scopus, and Cochrane databases were searched for articles published from January 2013 to December 2023, using the search terms: "focus," "foci," "small mass," "size," "breast magnetic resonance imaging," and "breast MRI." Extracted dat
