Coronal and sagittal reconstruction in computerised tomography.

Abstract

As useful and dramatic as axial computed tomograms are, severe limitations have been encountered. Most of these involve the accurate location of masses and, as in angiography, projections in several planes are essential. Recent advances in both hard and softward allow three millimeter slice thicknesses at low radiation dosage. Coronal and sagittal reconstructions are practical and obtained with ease. The computerized tomogram is invaluable in complementing standard neuroradiological procedures and, in some cases, allows definitive diagnosis. This degree of accuracy is not possible without multiplane reconstructions.
