Axial C.T. may detect a lesion, but accurate localization and evaluation of extent may be difficult. Multiple plane CT. provides three-dimensional anatomy and improved localization and extent of lesions. Recent technical advances in C.T. have enabled evaluation of lesion in multiple planes. Direct coronal scans have some limitations such as discomfort positioning, additional radiation exposure and inability of reconstruction of sagittal image. The SCI softward package allows to display sagittal or coronal images derived from a series of axial C.T. scans. This study reviews some of our experiences in computer reconstructed SCI of a variety of lesions within human body and attempts to illustrate the value of it. The SCI enables to provide the physician with all possible information relating a particular lesion to surrounding anatomic landmarks such as exact size and location of the lesion as well as increased specificity of diagnosis without the former's limitations. It is usefu in evaluation lesions of the skull base, apex and sellar region, determining if a lesion is intra-or extraventricular and intra-or extraaxial, and in distinguishing between supra-and infratentorial lesions. It is also helpful to determine approach of operation, to define portals of deep radiation therapy and chemotherapy and to evaluate the effect of treatment. Therefore, it is anticipated that referring physicians, especially surgeons, may benefit greatly from the availability of these images although they may also be diagnostically useful to radiologist.
