Objective To evaluate and discuss the usage of T2 reversed magnetic resonance (MR) image in neurosurgical operations. Methods T2 MR image was integrated in neuronavigation and then it was reversed. The T2 reversed image was used in image-guided neurosurgical operations in 36 cases to localize central sulcus and precentral gyrus. In 13 cases of a brain functional area tumor, the results of localization of central sulcus by somatosensory evoked potential (SEP) and precentral gyrus hand-knob by direct electrical stimulation (DES) were compared with those of reversed T2 guided navigation. Results The sulcus, gyms, brain surface vein, suture, pacchionian corpuscles, sinus, and brain edema were conspicuous in T2 reversed image. The reversed T2 image-guided navigation results of the central sulcus and the hand-knob were consistent with those of electrical examination completely. Conclusion The T2 reversed image is reliable in localizing sulcus and gyrus. It could substitute for SEP in localizing the central sulcus and provide more image information in neuronavigation.
