High-resolution Magnetic Resonance Vascular Wall Imaging Analysis Of Vascular Morphology Of Lenticulostriate Arteries In Healthy People

Objective: The high-resolution magnetic resonance vascular wall imaging technique was used to explore the differences in morphological characteristics such as the number and depth of soybean veins in healthy people of different age groups.Methods:Recruit 60 healthy subjects of different age groups,divided into group A(20~40 years)? group B(40~60 years)?and group C(60~80 years)by age.High resolution magnetic resonance wall imaging(HRMRA)3T MR system t1wi-3d visita sequence was performed on all patients.The image was processed by the post-processing application software Philips intelligent portal software.The minimum density projection method(minIP)was used to reconstruct the blood vessel image for analysis,and the number and depth of the branches of lenticular artery were observed,and statistical analysis was used SPSS 21.0.The comparison between independent groups of measurement data was performed by t test,the comparison between multiple groups was by single factor analysis of variance,and the LSD method was used for comparison between groups.Chi-square analysis was used to compare the count data between groups.Result:There was no statistically significant difference in the gender composition ratio between the three groups(P>0.05).There was no significant difference in the number and depth of bilateral lenticular arteries in right and left side of the same group(P>0.05).There was significant difference in the depth of bilateral lenticular arteries between each groups on the same side(P<0.05).After LSD comparison,There was significant difference in the number of bilateral lenticular arteries between group A and group C(P<0.05).There was no significant difference between group A and group B,and between group B and group C(P>0.05).conclusion:With the increase of age,the number and depth of lenticular artery branches decreased.High resolution magnetic resonance angiography has certain clinical value for morphological analysis of lenticular artery.
