초록
MRI를 이용하여 정상의 뇌량 크기를 측정한 결과 다음과 같은 결론을 얻었다. 1. 전체 대상자의 부위별 평균, 최소, 최대 1) Anteroposterior length는 평균 69.30mm, 최소 50.70mm, 최대 80.40mm이었다. 2) Diameter of genu는 평균 11.93mm, 최소 6.00mm, 최대 18.50mm이었다. 3) Diameter of mid body는 평균 7.00mm, 최소 3.40mm, 최대 10.40mm이었다. 4) Diameter of narrowing portion은 평균 4.51mm, 최소 0.80mm, 최대 9.50mm이었다. 5) Diameter of splenium은 평균 12.17mm, 최소 6.90mm, 최대 17.20mm이었다. 2. 전체 대상자의 성별에 따른 부위별 비교 1) Anteroposterior length는 남자가 여자보다 컸으며, 성별에 따라 유의미한 차이를 보였다. 2) Diameter of genu와 diameter of mid body, diameter of narrowing portion은 남자가 여자보다 컸으나 유의미한 차이는 아니었다. 3) Diameter of splenium은 남자가 여자보다 컸으며, 통계적으로도 유의미한 차이를 보였다. 3. 전체 대상자의 부위별 상관관계 1) Diameter of genu는 anteroposterior length와 통계적으로 유의미한 정적 상관관계를 보였다. 2)Diameter of mid body는 anteroposterior length, diameter of genu와 통계적으로 유의미한 정적 상관관계를 보였다. 3)Diameter of narrowing portion은 anteroposterior length와 통계적으로 유의미한 상관관계를 보이지 않았으나 diameter of genu, diameter of mid body와 통계적으로 유의미한 정적 상관관계를 보였다. 4)Diameter of splenium은 anteroposterior length와 diameter of genu, diameter of mid body, 그리고 diameter of narrowing portion과 통계적으로 유의미한 정적 상관관계를 보였다.
Abstract
As a result of measuring the size of corpus callosum in normal Korean people by using MRI, the following conclusions were obtained. 1. Maximum, minimum, and mean values by the region in whole subjects 1) Anteroposterior length amounted to the mean with 69.30mm, the minimum with 50.70mm, and the maximum with 80.40mm. 2) Diameter of genu amounted to the mean with 11.93mm, the minimum with 6.00mm, and the maximum with 18.50mm. 3) Diameter of mid body amounted to the mean with 7.00mm, the minimum with 3.40mm, and the maximum with 10.40mm. 4) Diameter of narrowing portion amounted to the mean with 4.51mm, the minimum with 0.80mm, and the maximum with 9.50mm. 5) Diameter of splenium amounted to the mean with 12.17mm, the minimum with 6.90mm, and the maximum with 17.20mm. 2. Comparison by region according to the gender in the whole subjects 1) Anteroposterior length was bigger in men than in women, and showed the significant difference depending on gender. 2) Diameter of genu, diameter of mid body, and diameter of narrowing portion were bigger in men than in women, but there was no significant difference. 3) Diameter of splenium was bigger in men than in women, and showed the statistically significant difference. 3. Comparison by region according to the age in the whole subjects 1) Anteroposterior length was the biggest in the 50s at the age, and was smaller in heir 10s than other age levels. In addition, the significant difference was indicated depending on age. 2) Diameter of genu and diameter of mid body were the biggest in their 30s, and were smaller in the 60s than other age levels. And, the statistically significant difference was indicated. 3) Diameter of narrowing portion was the thickest in their 20s, and was thinner in their 60s than other age levels. And, the significant difference was indicated depending on age. 4) Diameter of splenium was the thickest in their 30s, and was thinner in their 10s than other age levels. And, the statistically significant difference was indicated. 4. Correlation by region in whole subjects 1) Diameter of genu showed the statistically significant positive correlation with anteroposterior length. 2) Diameter of mid body showed the statistically significant positive correlation with anteroposterior length and diameter of genu. 3) Diameter of narrowing portion didn't show the statistically significant correlation with anteroposterior length, but showed the statistically significant positive correlation with diameter of genu and diameter of mid body. 4) Diameter of splenium showed the statistically significant positive correlation with anteroposterior length, diameter of genu, diameter of mid body, and diameter of narrowing portion.
