【摘要】Objective To investigate the diagnostic value of multi-slice spiral CT(MSCT) and its multi-planar reconstruction(MPR) and curved planar reconstruction(CPR) on sacroiliac joint with ankylosing spondylitis(AS).Methods Fifty-six patients with AS proved clinically were examined and analyzed with MSCT and reconstruction.Then the CT manifestations of sacroiliace joints were analyzed.And choose a sagittal image respectively in the margin of the sacrum one-four,one-second and two-four.Then went down the sacrum line trace for CPR technique get double sided sacroiliac joint imaging.The images,MPR transect images and CPR image were analyed.Results Early CT findings included coarsearticular

surface,interrupted

face,subcortical microcysts and sclerotic articular surface,while jiont space was normal.CT findings in progressive stage were uneven articular surface,damaged

microcyats,obviously sclerotic articular surface,extended jiontspace.In stable stage,CT findings included joint ankylosis,articular space dsiappearance,and sacroiliac ligament calcification.Fifty-six cases of AS
