Optimizing ultrafast dynamic contrast-enhanced MRI scan duration in the differentiation of benign and malignant breast lesions.

ABSTRACT:

Objective

To determine the optimal scan duration for ultrafast DCE-MRI in effectively differentiating benign from malignant breast lesions.

Methods

The study prospectively recruited participants who underwent breast ultrafast DCE-MRI from September 2021 to March 2023. A 30-phase breast ultrafast DCE-MRI on a 3.0-T MRI system was conducted with a 4.5-s temporal resolution. Scan durations ranged from 40.5 s to 135.0 s, during which the analysis is performed at three-phase intervals, forming eight dynamic sets (scan duration [SD]_40.5s: 40.5 s, SD_54s: 54.0 s, SD_67.5s: 67.5 s, SD_81s: 81.0 s, SD_94.5s: 94.5 s, SD_108s: 108.0 s, SD_121.5s: 121.5 s, and SD_135s: 135.0 s). Two ultrafast DCE-MRI parame
