Comparison of Fused Diffusion-Weighted Imaging Using Unenhanced MRI and Abbreviated Post-Contrast-Enhanced MRI in Patients with Breast Cancer

Sep 24, 2026

Uploaded by Stanley

To determine the percentage of breast cancers detectable by fused diffusion-weighted imaging (DWI) using unenhanced MRI and abbreviated post-contrast-enhanced MRI, 194 women with newly diagnosed unilateral breast cancer (October 2016–October 2017) underwent preoperative 3.0 T breast MRI including DWI. Fused DWI and abbreviated MRI were independently reviewed by two radiologists for index cancer detection, lesion characteristics, and conspicuity, with findings compared to histopathology. Index cancer detection rates were similar, while abbreviated MRI showed significantly higher lesion conspicuity for both radiologists.

FAQs

What was the study objective regarding MRI methods?

The study aimed to determine the percentage of breast cancers detectable using fused DWI with unenhanced MRI versus an abbreviated post-contrast-enhanced MRI approach.

How were the imaging techniques evaluated in the study?

Two radiologists independently reviewed fused DWI and abbreviated MRI for index cancer detection and lesion characteristics, and results were related to histopathological findings from surgical specimens.

Were index cancer detection rates different between the two MRI approaches?

Index cancer detection rates were comparable between fused DWI and abbreviated MRI, with no statistically significant differences reported for either radiologist.
