[Imaging of the spine].

Modern imaging techniques allow early and precise diagnosis of spinal diseases. Their sensitivity and specificity are variable, but in general they are more complementary than competitive. After emphasizing the different patterns which characterize the late evolution of diagnostic imaging, the author reviews the indications and limits of plain films, bone scintigraphy, computed tomography, and in particular of magnetic resonance, in trauma, degenerative lesions, inflammations, infections and tumors of the spine.
