Differential Diagnosis of Acute Vertebral Collapse Due to Osteoprosis or Metastasis Tumor in MRI / 中国医师杂志

ABSTRACT

Objective To analyze and sum up the MRI appearances of osteoporotic acute vertebral collapse(OAVC) or metastatic acute vertebral collapse(MAVC) and evaluate MRI value in both the differential diagnosis .Methods 30 cases of OAVC and 30 cases of MAVC were respectively collected at random according to clinical features,biochemical examinations,conventional radiograghy,and CT scan and all cases were studied with SE,T1-weighted images,gadolinium-enhanced T1-weighted images,and SE,T2-weighted images.Results 11 MRI apperances which were valuable in distinguishing OAVC from MAVC were summed up.Four images suggested that it was OAVC,one of which was specific:retropulsion of a bone fragment of collapsed vertebral body into the spinal canal.Seven images suggested MAVC,four of which were specific:dull-bell shaped body,destruction of pedicles,epidural mass,diffuse high or inhomogeneous signal intensity within the vertebral body on gadninium-enhenced T1-weighted images and T2-weighted images.Conclusion MRI is very useful in the differentiating OAVC from MAVC.
