ABSTRACT
Objective Toinvestigatethehemodynamicchangesofthegraymatterandwhitematterinpatientswithchronicmountain sickness(CMS).Methods 14CMSpatientsand12healthyvolunteerswererecruitedinthisstudy.Allofthem wereperformedbyroutineMRI andperfusionweightedimaging(PWI)scans.Aftertheappropriatepost-processing,therelevanthemodynamicparametersofdifferent graymatternucleiandwhitematteroffrontallobewereobtained,andthedifferenceofeachvaluebetweenthetwogroupswascompared.Results Therelativecerebralbloodflow (rCBF)decreasedinthebraingraymatterandwhitematterinCMSpatientswhencomparedwith normalgroup(P<0.05)[rCBFofthespleniumofthecorpuscallosum was(40.57±18.89)mL·100g-1·min-1forCMSpatients, and (64.56±18.55)mL·100g-1·min-1fornormalgroup],andatthesametime,meantransittime (MTT)andtimetopeak (TTP)werebothprolonged(P<00.5)[MTTofthespleniumofthecorpuscallosumwas(66.3±19.5)sforCMSpatients,and(48.0±2.17)sfor normalgroup;TTPofthespleniumofthecorpuscallosum was(26.86±4.67)sforCMSpatients,and (23.17±3.01)sfornormal group].Conclusion Collateralcirculation mayexistinCMSpatients’brain.Therearecerebralhemodynamicdifferencesbetween CMSpatientsandhealthyvolunteers.MRPWIisanimportantwayfordiagnosisofCMS.
