title: Limiting artifact in CT stereotaxic periventricular procedures. Technical note.
abstract: One potential source of computerized tomography image artifact during stereotaxic data acquisition is scatter from standard steel-tipped fixation pins as supplied for use with the Brown-Roberts-Wells stereotaxic headframe. In some cases, this can hinder selection of periventricular targets. Replacement of the steel-tipped pins with aluminum-tipped pins, which produce less artifact, helps to facilitate stereotaxic intervention.
