English Abstract:

  【Abstract】 Objective：To compare the value of radionuclide bone imaging and MRI in the diagnosis of osteoporotic vertebral compressive fracture.Method：Between February 2010 and December 2010，a total of 66 vertebrae from 24 cases（4 males and 20 females） with the mean age of 71.5 years old（range，60 to 82 years old） suffering osteoporotic thoracolumbar vertebral compressive fractures received X Ray，MRI and radionuclide bone imaging in the whole body with 99mTc-MDP，before experienced percutaneous kyphoplasty，in our hospital.Result：Of the compression vertebrae compared，60 vertebrae were positive for fracture on MRI and 58 vertebrae by bone scans.Four patients with entirely positive bone scans were negative by MRI，and two patients were entirely positive by MRI but negative by bone scan.The same vertebrae were 56，with a Kappa statistic of 0.72（P=0.000），indicating essentially excellent agreement.Conclusion：Radionuclide bone imaging was another good choice for the diagnosis of osteoporotic vertebral compressive fracture.Especially for cases exist contraindication of MRI，it could offer a reliable proof to decision-maker.
