The transabdominal sonographic examination of the lumbar intervertebral discs and the lumbar canal was carried out on 50 patients, for whom no existed clinical symptoms for a lumbosacral nerve root lesion. The sonographic device used was a mechanical sector scanner with a transducer with a frequency of 3.5 MHz. The transversal representation of the lumbar intervertebral discs and the lumbar canal was successful mainly at the height of the intervertebral space L4/5 (96%), less frequent at the height L3/4 (74%), L5/S1 (70%) and L2/3 (18%). The intervertebral disc and the intraspinal space at the height of the disc can be assessed in a transversal section, and thus the noninvasive sonographic method represents an improvement of the conventional X-ray-examination of the lumbar spine.
对50例无腰骶神经根病变临床症状的患者进行了腰椎间盘和椎管的经腹超声检查。所用超声设备为机械扇形扫描仪，换能器频率为3.5MHz。腰椎间盘和椎管的横向显示主要在L4/5椎间隙水平成功（96%），在L3/4（74%）、L5/S1（70%）和L2/3（18%）水平较少成功。椎间盘水平的椎间盘和椎管内间隙可在横断面上进行评估，因此这种无创超声检查方法是对传统腰椎X线检查的一种改进。
