neuroradiology - Diagnostic significance of T2W hypointensity of the sella - 09/10/09
Valeur diagnostique d’un hyposignal T2 de la région sellaire |
Normal anatomical structures and lesions characterized by low T2W signal intensity are reviewed in this pictorial essay. The purpose is to demonstrate how evaluation of the appearance, shape and exact anatomical location of the T2W hypointense sellar region structure, correlated with its T1W signal intensity, can based on the clinical context lead to an appropriate differential diagnosis.
