Radiographic diagnostic choice for brain stem lesions
What is the radiographic examination of choice for brain stem lesions?
Magnetic resonance imaging (MRI) is the examination of choice for suspected brain stem lesions.
It provides a highly sensitive and noninvasive method of evaluating the posterior fossa, unhampered by skull base artifact.
Enhancement with gadolinium may be useful to characterize breakdown of the blood–brain barrier.
Magnetic resonance angiography also may be helpful to investigate further the major branches of the vertebrobasilar system in brain stem ischemia or infarction.
