Diagnostic Evaluation of Articulations of Foot and Hand by 64-slice VCT Reconstruction / 实用放射学杂志

ABSTRACT

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.
