The ability to accurately classify breast lesions by MRI depends intimately on the ability to generate high resolution images with sharp margins and little blurring. Taking advantage of the increased spatial resolution afforded at 7T requires alleviation of the blurring caused by decrease in tissue T2 at this high field. An optimized modulated refocusing echo train that accounts for breast parenchymal tissue-specific T1 and T2 can generate signal plateaus that remain constant even for long refocusing trains, thus resulting in sharper point spread function. We present isotropic high-resolution 3D T2-weighted breast imaging at 7T (BreastVIEW) with improved edge detection.
