核磁共振及三维重建在奥美定面部填充患者中的诊断价值

摘要

目的：对MRI及三维重建在面部软组织的三维扫描及三维重建效果进行研究，以探讨其在奥美定面部填充患者中应用价值。方法：对15名接受奥美定面部填充患者进行MRI扫描，扫描数据以DICOM格式储存。在诊断工作站上以SSD法对图像进行重建。结果：在扫描层厚较小的情况下，MRI能完成面部大部分的软组织的三维扫描和重建，质量图像好，三维重建后，奥美定积聚区显影清晰。结论：MRI三维扫描及三维重建对于面部填充剂填充患者能够清晰显示填充剂填充范围、残留多少及体内形态，不仅有助于判断有无填充剂游离，而且可判断填充剂在体内的变化，可以作为面部填充剂填充患者术后进行随访检查的常规检查。%Objective To evaluate the reconstructed image of craniofacial soft tissue created by MRI, for the using of polyacrylamide hydrogel injection. Methods 15 patients was scanned by MRI .The date was recorded in DICOM format.The digital image was reconstructed on GE advantage workstation in SSD way. Results When the scan thickness was very thin ,MRI could undergo scanning and reconstructed most of head.It could reconstructed facial tissue And the quantity of image is very good. Conclusion MRI can be used to scan and reconstructed facial soft tissue ,and can be first choice for craniofacial reconstructed in polyacrylamide hydrogel injection patients.
