Three-dimensional computed tomographic reformations of sellar and para-sellar lesions
Tóm tắt
The purpose of this study was to determine whether diagnostically useful three-dimensional (3D) reformations could be obtained from unmodified high resolution pituitary CT scans. Twelve CT examinations in 9 patients in whom an enhancing tumour or extensive bone destruction was identified around the sella, were studied using 3D images obtained on soft tissue and bone thresholds. 3D images were considered superior to conventional CT sections and reformations for the assessment of the vascular relations of tumours with large supra-sellar components, and in cases of extensive bone erosion. In selected cases, 3D CT imaging may facilitate a faster and more comprehensive appraisal of high resolution CT studies by clarifying otherwise complex spatial relationships.
