LSA branches in symptomatic and asymptomatic unilateral MCA stenosis patients at 7T

Motivation: The annual stroke risk of symptomatic middle cerebral artery (MCA) stenosis patients is more than four times that of asymptomatic patients, and doctors need to identify these two types for personalized treatmentGoal(s): We aim to investigate whether there is a difference in the number of stems and branches of the Lenticulostriate Artery (LSA) between symptomatic and asymptomatic unilateral MCAstenosis patients at 7TApproach: Count the number of LSA stems and branches in the patient's cerebral hemisphere using 7T TOF MRAResults: :We found that the number of LSA branches varies between symptomatic and asymptomatic patientsImpact: LSA may serve as an imaging indicator for early diagnosis and personalized treatment of different types of MCA stenosis patients.
