Figure 2:

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.
