The authors performed spinal cord ultrasonography of 21 healthy newborn infants in Gyeongsna National University Hospital. Normal spinal cord revealed low echogenecity as that of cerevrospinal fluid and was demarcated by intense reflections from its dorsal and ventral surfaces. The central canal was routinely seen as a thin linear reflection in the center of the cord. The nerve roots making up the cauda equina formed a poorly defined collection of intense linear echoes extending from the conus. On real time image the normal spinal cord exhibited rather slow and rhythmical anteroposterior move-ment within the subaarachnoid fluid. A distinct and rapid vascular pulsation of the spinal cord was usually recognizable. The approximate level of vertebral bodies was determined as follows; most ventrally located vertebral body was thought to be 1.5 and S1 was seen slightly posterior to the 1.5 directed inferoposteriorly. According to the above criteria terminal portions of spinal cord were seen around the 1.2 body in 5MHZ and pointed termination of conus medullaris was clearly seen at L2-3 junction and in upper body of L3 by 7.5MHZ. So it would be better to examine by 5MHZ for spatial orientation and then by 7.5MHz. for more accurate examination. High-resolution rel-time ultrasonography was a safe rapid screening technique for evaluationof the spinal cord in infacts, Additional applications of spinal sonography may be possible in the evaluation of neonatal syr-ingogydromelia and meningocele as well as intraspinal cyst localization for possible percutaneous puncture by ultrasound guidance.
