    Intracranial tumor resection poses high risks due to complex brain anatomy, necessitating comprehensive presurgical imaging.

  • 2

    Access to advanced angiographic imaging is inequitable, particularly in low- and middle-income countries, due to cost and resource limitations.

  • 3

    A deep learning model was developed for automatic vessel segmentation on T1C MRI images to improve neurovascular imaging accessibility.

  • 4

    The study utilized a large multicenter dataset, including 1174 patients, to train and validate the deep learning model's performance.

  • 5

    Clinical validations demonstrated the potential of the deep learning model as an alternative to traditional angiographic methods.
