“Our study demonstrates that AB-MRI can be used as a cost-effective and time-saving imaging tool in the differentiation of IDP and ductal secretion. Our findings support that AB-MRI provides moderate-to-high diagnostic accuracy in making this distinction and significantly reduces imaging and interpretation times,” wrote lead study author Gulbanu Guner, M.D., who is affiliated with the Department of Radiology at the Umraniye Training and Research Hospital in Istanbul, Turkey, and colleagues.
Three Key Takeaways
1. AB-MRI Is a time- and cost-efficient alternative. For detection of intraductal papillomas (IDPs), abbreviated breast MRI (AB-MRI) significantly reduces imaging and interpretation time compared to full diagnostic breast MRI (FDB-MRI), taking about 6–7 minutes versus 25–30 minutes for imaging, and 43.49 seconds versus 71.21 seconds for interpretation.
2. Comparable diagnostic performance to FDB-MRI. Despite FDB-MRI having higher sensitivity, AB-MRI demonstrated no statistically significant difference in diagnostic accuracy for differentiating between IDPs and ductal secretions when compared to pathology results.
3. Higher specificity with AB-MRI. AB-MRI showed slightly higher specificity (57.14 percent) than FDB-MRI (50 percent), possibly due to its focused sequence evaluation, which may help reduce false positives caused by benign enhancing findings.
The study authors also noted comparable positive predictive value (PPV) between FDB-MRI (85.71 percent) and AB-MRI (an average of 84.96 percent). While acknowledging a lack of statistical significance, the researchers found that AB-MRI offered higher specificity (57.14 percent) in contrast to FDB-MRI (50 percent).
“This finding may reflect the focused evaluation of key post-contrast sequences, which potentially minimizes overinterpretation of subtle, non-specific findings. In contrast, the broader sequence set in FDB-MRI may increase false-positive rates by revealing benign enhancing foci such as adenosis or fibrosis,” pointed out Guner and colleagues. “Differences in patient population or lesion characteristics could also contribute to this observation, underscoring the importance of protocol optimization.”

Beyond the inherent limitations of a single-center retrospective study, the authors acknowledged the small cohort size and lack of external validation.
