[Computed tomography and magnetic resonance imaging for painful spinal column: contributions and controversies]

The use of tomographic imaging techniques, computed tomography (CT) and magnetic resonance imaging (MRI), to complement or replace plain-film radiography in the study of spine pain is becoming more and more common. The aim of this paper is to provide a general review of the CT and MRI manifestations of the wide spectrum of lesions that can cause pain in the spinal column. This spectrum includes degenerative disease, malalignment, tumors, inflammatory processes, and infectious processes. Precise knowledge and accurate reporting of the findings at CT and MRI are fundamental for clinical decision making in patients with spine pain.
