한국 성인에서 전산화단층촬영을 이용한 흉치강의 측정 = Measurement of Thoracic Spinal Canal by Computed Tomography in Korea Adults

다국어 초록 (Multilingual Abstract)

The size of spinal canal is valuable to detect the body encroachment of spinal canal and expansion due to tumors by computed tomography. This study was designed for taking accurate measurement of the normal thoracici spinal canal in Korean adults. The anteroposterior diameter, interpediculate distance and cross-section area of thoracic spinal canal were measured in 80 normal adults. The results were as follows. 1. In A-P diameter, middle parts of the canal were smaller vaues than those of upper and lower parts from T1 to T6, and upper parts of the canal were larger than those of middle and lower parts from T7 to T10. 2. In interpediculate distance, middle parts of the canal revealed larger value than those of upper parts. 3. All measurements of male were larger than those of female at all levels of the spinal canals and 65 measurement (93%) were statiscally significant.
