ABSTRACT
<p><b>OBJECTIVE</b>To explore the clinical value of imaging diagnosis of the vertebral injury in earthquake.</p><p><b>METHODS</b>Twenty-two cases of the vertebral injury in earthquake with clinical and imaging data were analyzed retrospectively. All of the cases were performed X-ray plain film examination, CT in 20 cases and MRI in 15 cases.</p><p><b>RESULTS</b>Imaging examination can establish definitive diagnosis in all cases. In the 22 cases, the vertebral compression fracture was found in 20 cases, and vertebral bursting fracture in 2 cases,single-level vertebral fracture in 12 case,and multiple-level vertebral fracture in 10 case. Among the 31 vertebral bodies of fracture, the fracture of cervical vertebra, thoracic vertebra, lumbar vertebra and sacral vertebra was found in 3, 12, 14, 2 vertebral bodies, respectively.</p><p><b>CONCLUSION</b>Imaging examination is the most valuable examination method in diagnosis of the vertebral injury in earthquake. It can not only make definitive diagnosis, but also play an important role in selection of therapeutic method.</p>

Objective To study the value of DSA for hepatic vascular anatomy,and to evaluate the efficacy of portal vein occlusion in rabbits with hepatic VX2 tumor.Methods Twenty New Zealand white rabbits were randomly divided into two groups with 10 in each group,including test group A and positive control group B of ham operation.For the test group A,portal branch ligation(PBL)was performed for the left external branch after 3 weeks of the tumor implantation to the left external lobe.Two weeks later,the DSA of hepatic artery and portal vein were performed in all of the rabbits.Results The total displaying effectiveness of the branches of hepatic artery by DSA was better than that by vascular perfusion.There was hypovascular blood supply to hepatic artery implantation of the tumor in the test group A,comparing with that of the group B.Conclusion DSA can clearly display spacial details of the hepatic vascular anatomy in rabbits,and play an important role in post-procedual evaluation of the portal vein occlusion in rabbits.
