What is Magnetic Resonance Imaging Characteristics Predict Pituitary Function in Non-functional Pituitary Macro-adenoma Undergoing Trans-sphenoidal Surgery about?

## Abstract ## Introduction Maintaining the pituitary function after surgery is highly important. The aim of this study was to investigate the relationship between preoperative magnetic resonance imaging (MRI) characteristics and pituitary function after surgery of non-functional pituitary macroadenoma. ## Methods This retrospective study was performed between 2016 and 2018. Preoperative and postoperative MRI imaging data were retrieved from electronic registration system. The relationship between preoperative MRI characteristics and postoperative pituitary function as well as reconstruction of pituitary gland was investigated using regression models. ## Results Complete data were available for 44 patients. Before surgery, invisible normal tissue was observed in 23 patients (53.5%). Suprasellar extension and cavernous sinus invasion were seen in 36 patients (each one 49.1%). There was a significant reverse relationship between preoperative tumor size and postoperative thyroid stimulating hormone (TSH) (odds ratio (OR): − 0.99 (− 0.18, − 0.003),p = 0.04). In addition, we found a significant positive correlation between prolactin level after surgery and tumor size before surgery, (OR
