摘要
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(MPR)、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。
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.
