Conventional Radiography and MRI for the diagnosis of vertebral metastases
Main Article Content
Abstract
SUMMARY
Purpose: Describe the imaging characteristics and evaluate the value of conventional radiography and MRI for the diagnosis of
vertebral metastases.
Material and methods: 62 patients with vertebral lesions suspected metastates were taken biopsy at radiology department
in Bach Mai Hospital from November 2011 to August 2013.
Result: A total of 42 patients with vertebral metastases,male/ female 26/16, the mean age is 57.43 ± 13.29. The percentage of lesions detected on X-ray were 52.4% with the sensitivity of signs of vertebral collapse,condensation of vertebral body, pedicle
destruction were 31.8%; 18.7%; 21.4%. MRI: the sensitivity, specificity, accuracy were 97.6%; 75%; 90.3%.
Conclusion: Although X-ray is the first method but less valuable in diagnosing vertebral metastases. Magnetic resonance imaging has great value in the diagnosis of vertebral metastases with many special signs.
