Using the magnetic resonance three-dimensional volume rendering for tissues technique in the planning of craniotomy flaps with linear scalp incision.
Preoperative three-dimensional images with surface venous anatomy may be used in the planning of a linear scalp incision and the opening site of the dura mater for protection of surface veins during surgical dissection, and to find the splitting site of the brain according to the lesion. In 45 patients who had a brain tumor, linear scalp incision planning was done by regarding the three-dimensional images derived from post-contrast time-of-flight (TOF) sequence raw data. The findings of correspondence and the quality of routine contrast-enhanced magnetic resonance imaging (MRI) and three-dimensional volume rendering for tissues (VRT) images were analyzed separately with the surgical findings according to a visual grading system. Our experience revealed that the surgical findings correlated well with the three-dimensional VRT images. According to a visual surgical grading system, a grade III correlation was found in 20 (45%), grade II in 15 (33%), grade I in 7 (15%), and grade 0 in 3 (7%) patients in our study population. At the end of our research we conclude that this method is useful in terms of the preoperative determination of brain surface anatomy and may be used in the determination of the site of a linear scalp incision according to the localization of an intracranial lesion.
