title: Prefrontal sonic treatment: MR findings.
abstract: The authors describe the use of MR in a patient who underwent prefrontal sonic treatment for relief of intractable headaches. MR demonstrated well-demarcated regions of encephalomalacia within the white matter of the frontal lobe (with relative sparing of cortex) in a characteristic conical volume that corresponded to the insonified regions.
