Objective To investigate the methods of MRI 3D reconstruction of dural tail sign of meningiomas and its guiding significance for meningioma resection.Methods Twenty-three patients with convexity meningioma and parasagittal meningioma with dural tail sign on contrast-enhanced MRI-T1 images treated at the Department of Neurosurgery of Linyi People' s Hospital,Shandong Province were selected from May 2013 to November 2014.After injection of gadolinium diethylene-trianmine pentaacetic acid (DTPA) enhancer,MR 3D-FLASH TIMPR sequence axial scanning was performed,and the layer thickness was 1.5 mm.the syngo program was used to perform the 3D reconstruction of dural tail sign.The vertical diameter and anteroposterior diameter of meningioma dural tail sign on the enhanced T1 MRI tomographic images and 3D reconstruction images were measured and compared.The surgical incisions were designed by using the 3D reconstruction images of dural tail sign,and their advantages and disadvantages were evaluated under the guidance of navigation.Results Dural tail sign performed MRI 3D reconstruction could reveal its overall picture.Most of dural tail signs around the tumors were uneven.The dural tail sign extended farther nearby the dural vessels.The vertical diameters of dural tail sign measured on contrast-enhanced T1-MRI were 2.74-7.54 cm (mean 4.67 ± 1.234 cm);the vertical diameters of dural tail sign measured on 3D reconstruction irrages were 2.75-7.64 cm (mean 4.70 ± 1.249 cm).There was no significant difference between both of them (P > 0.05).The anteroposterior diameters of dural tail sign measured on contrast-enhanced T1-MRI were 2.84-7.61 cm (mean 4.81 ± 1.19 cm);the anteroposterior diameters of dural tail sign measured on 3D reconstruction images were 2.88-7.74 cm (mean 4.85 ± 1.22 cm).There was no significant difference between both of them (P >0.05).Designing surgical incisions referring dural tail sign 3D reconstruction images,the excellent rate was up to 91%.Conclusion MRI 3D reconstruction can intuitively and accurately reveal the range and shape of dural tail sign,and thus provide evidence for meningioma incision design and dural resection range.
