OBJECTIVE: To evaluate the value of CT and MRI in the diagnosis of @entity2530 of the vertebral body (ANV). METHODS: Twelve ANV @entity1 were retrospectively analysed by their medical history, clinic manifestation, CT and MRI. Twelve AVN @entity1 were treated with percutaneous vertebroplasty ( @entity12468 ). The @entity158 level of each @entity1 was assessed, both before and after the procedure, using a visual analogue scale (VAS). RESULTS: All the @entity1 had ANV in the thoracolumbar spine. The intravertebral vaccum phenomenon (VP), with gas or fluid-like collection, was seen on computed tomographic (CT) images and magnetic resonance images (MRI). In the early stages, the VP zone was characterized by fluid-like collection, and was low intensity on T1, high intensity on T2. In the latter stages, the margin of VP zone had sclerotic change on CT scan. VAS score decreased from preoperative (9.08 +/- 0.76) to (2.33 +/- 1.43) at 3 days after @entity12468 . CONCLUSION: ANV must be considered as a possible diagnosis of @entity3604 . Both CT and MRI could provide reliable diagnostic proof for ANV. @entity12468 is proved to be an effective and safe procedure for the treatment of ANV, and could provid quick @entity158 relief.
