Abstract:
Objective To investigate the relationship between MRI signal type and CT structural characteristics on lumbar hy-perostogeny ,and the possible mechanism of vertebral body remodeling on degenerative lumbar spine .Methods Imaging data of for-ty-five subjects who were referred for both MRI and CT imaging of the lumbar spine from July 2011 to January 2012 were retro-spectively analyzed .Volume Rendering(VR) and Multi-Planar Reformation(MPR) were used to observe structural characteristics of osteophyte .Osteophyte formation ,MRI signal type and CT features of osteophyte were recorded ,then analyzed their relationship . Results 45 subjects contain 225 vertebral bodies ,there were 38 vertebral bodies containing osteophyte visible to naked eye .The four types of MRI signal were type Ⅰ to type Ⅳ ,accounting for 2(5 .3% ) ,4(10 .5% ) ,10(26 .3% ) and 22(57 .9% ) ,respectively . The three types of CT structural characteristics are type A to type C ,accounting for 4(10 .5% ) ,11(28 .9% ) and 23(60 .5% ) ,re-spectively .The main MRI signal of type A is type Ⅱ(100% ) ,and that of type B and C are both type Ⅳ(72 .7% and 65 .2% ) .Con-clusion There is a corresponding relation between MRI signal type and CT structural characteristics on lumbar hyperostogeny . Constant reconstruction of osteophyte remodels vertebral body on degenerative lumbar spine .
