Abstract

The fractional anisotropy value of the brain white matter region was analyzed by Tract-Based Spatial Statics(TBSS) method after acquiring the diffusion tensor image to identify the presence or absence of brain white matter damage to smoking in male. As a result, smokers showed lower fractional anisotropy than non-smokers in all areas but fractional anisotropy values were not statistically significant. the fractional anisotropy value, on the other hand, was statistically significant only for the right choroid plexus. In other words smoking, although, does not significantly affect the micro structural changes of brain white matter, it affects the choroid plexus area.

흡연 유무의 남성을 대상으로 뇌 백질의 손상 유무를 파악 할 수 있는 확산텐서영상을 검사하여 영상을 획득 한 후 Tract-Based Spatial Statics(TBSS)방법으로 뇌 백질 부위의 신경섬유로의 비등방도 FA(fractional anisotropy)값을 측정 분석한 결과 모든 영역에서 흡연자가 비흡연자보다 비등방성 측정값이 낮게 나타났지만 FA값은 통계적으로 유의하지 않았으며 오른쪽 맥락총 부위에 대한 FA값에서만 통계적으로 유의하였다. 본 연구의 결과 값으로 추측하자면 즉 흡연이 뇌 백질의 미세구조성 변화에 크게 영향을 미치지는 않지만 맥락총 부위에는 영향을 미친다고 할 수 있다.
