Abstract:
Objective To explore the applied value of high-field intraoperative magnetic resonance imaging (iMRI) in multi-image fusion guided stereotactic brain biopsy.Methods Twenty-four patients with intracranial lesions were examined by conventional MRI and diffusion tensor imaging (DTI) with 1.5T iMRI system before operation in our hospital from June 2011 to April 2012.The digital image data and preoperative PET/CT image data were transferred into BrainLAB planning workstation and all kinds of images were automatically fused.We used the BrainLAB software to reconstruct the corticospinal tract (CST) and three-dimensional display the anatomic relationship of CST and brain lesions.Leksell surgical planning workstation was used to help to choose the best target site and the reasonable needle track.The 1.5T iMRI was used to effectively monitor the intracranial condition during brain biopsy procedure.Results Needle biopsies were successfully performed in all 24 patients and pathological diagnosis was explicitly obtained in 23 patients,leading to a diagnostic yield of 95.8％.No patient suffered from significant complications during or after surgery.Conclusions With the help of high-field iMRI,multi-image fusion guided stereotactic brain biopsy conduces to achieving the purpose of higher positive rate of biopsy and lower incidence of complications.The method with this design combining MRI-DTI fusion images with the frame-based stereotactic biopsy can play a significant role in intracranial lesions of deep functional areas.
