RT Journal Article SR Electronic T1 Sellar Contour: Anatomic-Polytomographic Correlation JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 331 OP 334 VO 2 IS 4 A1 Turski, Patrick A. A1 Newton, Thomas H. A1 Horten, Bruce H. YR 1981 UL http://www.ajnr.org/content/2/4/331.abstract AB In the polytomographic evaluation of the sella, the spectrum of normal sellar contour is broad. Minimal sellar contour changes may be insignificant. Therefore, the polytomographic diagnosis of pituitary microadenomas should be limited to those patients with definite focal, usually asymmetric, expansion of the sellar floor.
