Direct coronal computed tomography of the lumbar spine: a new technical approach in supine position

Computed tomography (CT) was carried out on 46 subjects with L5-S1 disk hernia. All the patients had a L5-S1 angle equal or greater than 40 degrees. Coronal sections of the disk were obtained with a rostral angulation of the gantry, having placed the lumbar spine in a hyperlordotic position. Results are discussed and compared with those obtained from para-axial transverse sections and multidirectional reformated images.
