目的探讨多层VCT(MSCT)后处理重建技术在手足关节疾病诊断中的应用价值.方法对50例手、足关节病变行MSCT扫描.并进行后处理重建,重建技术有多平面重建(MPR)、表面遮盖(SSD)、最大密度投影(MIP)和容积再现(VR),分析病变情况.结果骨折33例,X线共发现骨折40处,MPR、VR共发现51处.7例涉及关节面的骨折,VR和MPR显示最佳,清晰显示骨折全貌.SSD很好显示骨折脱位周围软组织、皮肤表面血管.4例石膏外固定的病人运用MIP成像,对比平片得到更为清晰的骨的三维图像.结论 64层VCT后处理重建技术在手足关节疾病诊断中具有很高的应用价值.

Objective To evaluate the diagnostic value of 64-slice VCT reconstruction techniques in the diseases of joints of foot and hand.Methods 50 patients with diseases of joints of foot and hand underwent MSCT scans,the data were reconstructed,including multiplanar reconstruction(MPR),maximum intensity projection(MIP),shaded surface display(SSD)and volume rendering(VR),the results were analysed.Results 33 patients with fractures,40 and 51 fractures were found by X-ray and MPR,VR,respectively.The joint surface involved in 7 fractures,which was best with VR and MPR to show the whole fractures.SSD was better to demonstrate the soft tissue and the vessels of the skin.3D bone reconstruction with MIP was better than plain film in showing the fractures in 4 patients with plaster external fixation.Conclusion 64-slice VCT reconstruction techniques are effective in diagnosis of the diseases of joints of foot and hand.
