The research of remodeling pattern in middle cerebral artery atherosclerotic disease:high-resolution magnetic resonance
摘要
Abstract
Objective The application of HRMRI in middle artery atherosclerotic remodeling pattern.Methods Seventy-five cases of moderate to severe middle cerebral artery atherosclerotic stenosis imaging data were analyzed.Vessel area and lumen area of maximum stenosis in middle cerebral artery and reference were measured respectively.The WA,PA,PB,RI,SR were calculated respectively.According to the remodeling index,75 cases were divided into positive remodeling and non-positive remodeling group.The parameters were compared between two groups.Results The RI in two groups were (0.86±0.10) and (1.36±0.30) respectively.There was significant difference between the two groups (P<0.001).VA,PA was significantly different in two groups at the maximum luminal narrow site (P<0.001).LA,WA,PB was significantly different in two groups (P=0.009,P=0.001,P=0.002).As for SR,there was no significantly different between two groups (P=0.106).VA was significantly different between two groups at reference site (P=0.013).LA and WA was no significant difference between two groups(P=0.494,P=0.065).Conclusion The features of the MCA atherosclerotic stenosis was clearly shown in the HRMRI.That was important for evaluating the remodeling pattern.Non-PR was as normal as PR.The VA,LA,WA,PA and PB in PR was bigger than that in non-PR.The patients in PR group was more terrible than non-PR group.In a word,evaluating the remodeling pattern was beneficial for patients.关键词
