RESULTS:
All n=56 of patients were charted and broken down based on factors related to gross total resection status of their tumor and frequency of use of iMRI during their procedure. Of these 56 patients, 10 of them had documented post-operative MRI results in our data set and their outcomes related to identifiable tumor residual was charted as well.
Gross total resection was observed in 67% (n=37) of patients who underwent iMRI during the resection of their tumor. 33% (n=19) of patients who underwent iMRI did not achieve gross total resection of their pituitary mass (Figure 1). The reasons for not pursuing gross total resection in these patients are further outlined in the discussion section.
IMRI was used exactly one time in a single case in 96% (n=54) of patients during tumor resection. IMRI was used more than once in a single case in 4% (n=2) of patients during tumor resection. (Figure 2).
Post-operative tumor residual was found in 32% (n=6) of patients in our data set of n=19 patients who underwent postoperative MRI (Figure 3).
