Abstract:

Objective  To compare the image characteristic of SAPHO syndrome by X-ray and CT findings as well as 99mTC-MDP bone imaging for accurate diagnosis of this entity. Methods  The imaging property was examined on X-ray, CT and 99mTC-MDP bone imaging in 22 cases and compared with the advantages and disadvantages. Results  SAPHO syndrome presented distinctive features by different imaging technique, and the nature appeared prominent on X-ray and CT images, yet was more sensitive to 99mTC-MDP. Conclusion  Patients with suspected SAPHO syndrome may receive early examination by X-ray or CT, and additional nuclide bone imaging, as appropriate, may improve the diagnostic accuracy.
