Comparison of brain abscess on conventional DWI and DL-DWI. A 64-year-old male visited emergency room with seizure. Conventional DWI revealed an approximately 2cm lobulated contour, diffusion restricted lesion with perilesional edema in the left parietal lobe (a, b). With DL-DWI, the lesion clearly demonstrated better contrast (c, d), leading to brain abscess diagnosis.
