ABSTRACT
Objective:
To study the morphology of middle cerebral artery ( MCA ) M1 segment .Me-thodsWe selected the MRA data of 794 MCA (400 of the left side and 394 of the right side ) from Ja-nuary 1, 2011 to June 30, 2011 consecutively and analyzed the morphology of the MCA M 1 segment in axial, anteroposterior and lateral view , measured the length of the M1 segment, and analyzed the simila-rity of the left and right side M1 segment morphology .Results:
In axial, anteroposterior and lateral view , the MCA M1 segment showed C-shape >L-shape >S-shape .In axial view , it was about 373 ( 47%) M1 segment performance for the C-shape, of which 340 (42.8%) M1 segments showed bowing to the dorsal side, only 33 (4.2%) M1 segments showed bowing to the ventral side .In anteroposterior view, it was about 322 (40.6%) M1 segments of the performance of the C-shape, of which 262(33.0%) M1 segments showed a bowing to the superior , 60 (7.6%) showed bowing to the inferior .The similarity of the left and right MCA M1 segments was 27.2% (114/419) in axial view and 42.7% (179/419) in anteroposterior view.It was more similar in anteroposterior view than in axial view .Along with the increase of age, in the axial view, L-shape converted to C-shape very obviously, but only mildly elevated in S-shape .In anteroposterior view , the L-shape converted to the C-shape or S-shape along with the increase of age.Conclusion:
The different morphology of MCA M1 segment in axial and anteroposterior view may be involved in the development of intracranial atherosclerosis .
