Computer reconstructed sagittal and coronal computed tomography head scans: clinical applications.

Recent technical advances to computed tomography (CT) have enabled evaluation of the head in multiple planes. A technique that utilizes computer reconstruction of data from 3 mm contiguous transverse scans to display images in sagittal and coronal planes is described. The clinical usefulness of this technique is discussed and illustrative cases are presented. Multiple plane CT evaluation has proven a valuable adjunct to axial plane CT scanning, which can provide better definition of the extent of lesions, facilitate treatment, and improve diagnostic accuracy in many cases.
