Computed Tomographic Cisternography of the Sellar and Parasellar Region: A Radiological Approach to Cisternal Anatomy
With the introduction of microsurgical techniques in neurosurgery new requirements have been established for the radiological management of the sellar region. For planning an operation the surgeon needs exact information about the extension of lesions and their encroachment upon surrounding structures (Yasargil 1984). Concerning the parasellar cisterns computed tomographic (CT) cisternography with metrizamide is a suitable method to visualize both nerval and vascular contents and its spatial relationships (Dickob 1987; Galanski et al. 1986). It is superior to magnetic resonance imaging (MRI) in image acuity and should be performed if more details were needed than intravenous contrast-enhanced CT or MRI can provide.
