ABSTRACT Background: Localization and delineation of extent lesions is critical for safe maximal resection brain spinal cord tumors. Frame-based frameless stereotaxy intraoperative MRI are costly not freely available especially in economically constrained nations. Intraoperative ultrasound has been around a while but relegated to the background. Lack objective evidence its usefulness perceived “user unfriendliness” US probably responsible this. We recount our experience with this “forgotten” tool propose an assessment score utility attempt revive practice. Materials Methods: Seventy seven (IOUS) studies were carried out patients Seven parameters identifi ed measure “utility” IOUS “utility score” was devised (minimum 0 maximum 7). Individual parameter overall scores calculated each case. Results: found be useful many ways. The median 6 (mean 5.65). There no less than 4 majority demonstrating 5 or more (91%). use signifi cantly infl uenced performance surgery these cases without prolonging surgery. Conclusions: very localization planning various stages tumor resection. It easy, convenient, reliable, widely available, above all cost-eff ective tool. should increasingly used by neurosurgeons developing world where costlier imaging freely.
