In this research, territorial Arterial Spin Labelling (t-ASL) and unenhanced 3D-TOF-MRA were used to evaluate the usage in identification of the feeding vasculature of meningiomas in 20 consecutive patients. Results showed that the inter-observer agreement was excellent for the identification of the origin of the feeding arteries by t-ASL, which was better than the inter-observer agreement of 3D-TOF-MRA. The inter-modality agreement between t-ASL and 3D-TOF-MRA for the feeding arteries was moderate. The information about feeding arteries was potentially related to patients’ symptoms and pathology, making it crucial for neurosurgeons in planning surgery and evaluating prognosis.
