Relative Roles of Radiologists and Other Physicians in Percutaneous Endovascular Neurointerventions

Radiologists continue to maintain a strong presence in the field of neurointerventional radiology, particularly in percutaneous intracranial interventions, performing 51% of all intracranial procedures in 2013, down from 80% in 2000. However, neurosurgeons have made substantial inroads into ENI procedures, with their volume increasing from 10% to 33%, from 2000 to 2013. The overall volume of ENIs rose steadily from 2000 to 2013.
