MRA delineation of the vertebral-basilar system in patients with hemifacial spasm and trigeminal neuralgia.
Detailed depiction of the vertebral-basilar system is often obscured by other vascular structures on the MR angiogram. A special MR angiography technique that can better delineate the branches of the vertebral-basilar system has been designed and has proved particularly useful in the identification of tortuous vascular branches when they come in contact with the seventh or fifth cranial nerves.
