title: MR of the diaphragma sellae.
abstract: The appearance of the diaphragma sellae is described in cryomicrotomic sections and on MR in patients with and without intra- and suprasellar masses. On MR, it appears as a thin band of negligible signal that is best shown when adjacent CSF or a mass has greater signal intensity. Its position or absence can be used to differentiate intrasellar masses with suprasellar components from suprasellar masses.
