Trace dw imaging
Spletdiffusion-weighted (DW) imaging is more sensitive than conventional MR imaging in distinguishing brain abscesses and cystic tumors (2–8). Pus in brain ab-scesses is strongly hyperintense on trace DW images and has a reduced apparent diffusion coefficient (ADC). On the contrary, most necrotic or cystic brain Spletstrengths, we are able to generate higher b values for diffusion-weighted (DW) imaging. Our purpose was to evaluate the appearance of the normal brain on DW MR images as the diffusion gradient strength (“b value”) is increased from 1,000 to 3,000 s/mm2. Method: Three sets of echo planar images were acquired at 1.5 T in 25 normal
