Perfusion changes associated with intratumoral embolization and feeder occlusion for meningiomas: an arterial spin labeling study
Key Points
This research investigates the impact of two interventions on blood flow in meningiomas.
Retrospective cohort analysis
Comparison of intratumoral embolization and feeder occlusion
Assessment of tumor blood flow via arterial spin labeling (ASL)
Intratumoral embolization resulted in a greater reduction in tumor blood flow
Feeder occlusion showed less reduction in blood flow compared to embolization
Abstract
In this retrospective cohort, intratumoral embolization was associated with a greater reduction in tumor blood flow than feeder occlusion as assessed by ASL.
