MR Textural Analysis on Contrast Enhanced 3D-SPACE Images in Assessment of Consistency of Pituitary Macroadenoma

Wenting Rui1


This study aimed to explore the value of MR textural analysis in assessing consistency of pituitary macroadenoma (PMA) based on contrast enhanced (CE) 3D-SPACE images. Fifty-three patients with PMAs that underwent CE 3D-SPACE scanning and endoscopic trans-sphenoidal surgery were included. First-order energy and second-order correlation negatively correlated with hard PMAs, while first-order entropy and second-order variance, sum variance, and sum entropy positively correlated with stiffness (P<0.05). Diagnostic accuracy of combined negative features could achieve an AUC of 0.819, and an AUC of 0.836 of positive features (P<0.001). MRTA using CE 3D-SPACE images is helpful for assessing PMA consistency preoperatively and noninvasively.
