Abstract:
Both signal intensity on trace images and apparent diffusion coefficient measurements on mapped images evolved rapidly on serial diffusion-weighted sequences in a case of pyogenic brain abscess that was monitored primarily by MRI before a biopsy was performed. Considering only the signal intensities on the trace images would have led to an underestimation of the intrinsic tissue changes.
