Narrowing of the central sulcus, upward shift of the brain, and narrowing of CSF spaces at the vertex occurred frequently and predominantly in astronauts after long-duration flights. Further investigation, including repeated postflight imaging conducted after some time on Earth, is required to determine the duration and clinical significance of these changes.

MRI显示太空飞行对宇航员大脑结构的影响

长时间飞行后，宇航员经常发生中央沟变窄，大脑向上移动以及顶点处的CSF空间变窄的情况。需要进一步的研究，包括在地球上一段时间后进行的飞行后重复成像，以确定这些变化的持续时间和临床意义。（由国家航空航天局资助。）
