Normal and high accuracy computed tomography of the brain: dose and imaging considerations.
The high accuracy scanning mode of the EMI CT1010 scanner generates scans with imaging characteristics superior to those produced in the normal accuracy mode. The comparative dosimetry of normal and high accuracy scans is presented, along with an analysis of the image quality of the two scanning modes. High accuracy scanning is an effective adjunct in patients with difficult lesions in the cerebral hemispheres.
