[X-ray computed tomographic exploration of cervico-brachial neuralgia. Value of the intravenous injection of contrast media].

Cervicobrachial neuralgias can now be easily evaluated by computerized tomography of the cervical spine due to recent technical progress (improved resolution, ultra-thin cuts, precise localization by computed radiography), and especially the use of intravenous contrast material, thus avoiding intrathecal metrizamide. The authors describe normal findings obtained by this method as well as disk herniations and disco-uncarthrosis. On the basis of this initial study of 35 patients (7 disk herniations and 16 disco-uncarthrosis), this method could be employed following routine studies as the first preoperative examination for cervicobrachial neuralgia. Thus, the indications for cervical myelography would decrease, limiting the use of a more invasive procedure and patient discomfort.
