[The role of TC and MRI in the identification, characterization and staging of tumors of the spinal vertebrae].

The early detection and characterization of primary and metastatic spinal bone tumors permits early and appropriate surgical or nonsurgical intervention directed toward preserving life and function. The sensitivity and multiplanar capabilities inherent in Magnetic Resonance imaging make it the imaging procedure of choice in detecting and characterizing a spinal bone lesion. Spiral Computed Tomography with multiplanar reconstruction may be a useful supplementary procedure, especially when detailed bony anatomy, particular of the posterior elements, is required for surgical intervention. Plain films play little if any role in modern imaging. The may be used as screening procedures in situations in which MR and CT are not available.
