Spinal infections (pyogenic or non-pyogenic) are increasing in incidence and are a common cause of morbidity in high-risk patients (elderly, immunocompromised patients, diabetic patients, drug addicts, and patients with sickle-cell disease).To provide an overview of the radiological features of spinal infections, focusing on magnetic resonance (MR) imaging, and to illustrate the differential diagnosis.We reviewed the spine imaging of 118 patients with spinal infections from our files. All patients underwent radiography and MR imaging examinations. computed tomography (CT) was performed in 96 patients.MR imaging has greatly contributed to prompt diagnosis, thus allowing implementation of timely appropriate treatment.Prompt diagnosis and treatment are essential to prevent serious bone and joint destruction, and severe neurologic sequelae.
