Images obtained at diffusion-weighted imaging (DWI) by using conventional
(left) and MB SENSE–accelerated (right) acquisitions in a
36-year-old participant with a 43-mm grade 3 invasive ductal carcinoma
(arrow, outline). Good image quality was observed (shown are
b = 0 and b = 800
sec/mm2 images) on images obtained by using both
sequences (with two of three readers rating them equal [0] and one
preferring MB SENSE [+1]), and the resulting apparent diffusion
coefficient (ADC) maps (bottom) were also very similar both
qualitatively and quantitatively. The tumor mean ADC values (within the
outlined regions of interest shown) were closely matched, with ADC =
0.82 and 0.86 × 10–3 mm2/sec for
conventional DWI and MB SENSE DWI, respectively. MB = multiband, SENSE =
sensitivity encoding.
