MSCT对腹膜后寄生胎的诊断价值

目的：探讨腹膜后寄生胎MSCT轴位图像及后处理图像的表现，进一步提高对该病检查方法的认识。方法：2例临床可疑诊为腹膜后寄生胎患儿先行MSCT平扫，再将原始薄层图像传至AW4．2工作站进行多平面重组（仲R）、容积再现（VR）和最大密度投影（MIP）；观察轴位、MPR、VR、MIP影像学特征。结果：2例轴位图像示中上腹见一混杂密度影，形态不规则，边界清楚，其内见液体、脂肪、骨骼和软组织密度影，后处理图像示脊柱、骨盆及部分四肢影像。结论：MSCT后处理技术对腹膜后寄生胎具有较高诊断价值，特别是VR可以直接提供寄生胎的影像学特征性表现。

The Diagnostic Value of Multislice CT in Retroperitoneal Parasitic Foetus

Objective： To evaluate retroperitoneal parasitic foetus of MSCT axial images and image postprocessing performance, further improve the understanding of the disease inspection method. Methods： 2 cases of clinical suspected diagnosis of retroperitoneal parasitic foetus with MSCT scan first, then the original image to AW workstation 4.2 a thin layer of multiplanar reconstruction （MPR）, volume representation （VR） and maximum density projection （MIP）; Observation of axial, MPR, VR, probably have shown in the image to see a mixed density fat, bone, soft tissue density with post processing image in MIP imaging characteristics. Results： 2 cases of axis of with irregular shape, clear boundary, which see liquid, the spine, pelvis, and part of limbs. Conclusion： MSCT post-processing techniques of retroperitoneal parasitic has high diagnostic value, especially VR can directly provide parasitic foetus imaging characteristic.
