70551 MRI brain stem without dye
Also known as: brainstem MRI, MRI brainstem noncontrast, pons MRI, MRI brain without contrast, brain MRI, brain MRI without contrast
Magnetic resonance imaging of the brainstem without intravenous gadolinium contrast medium. High-resolution imaging evaluates brainstem structures including midbrain, pons, and medulla.
In Plain Language
brainstem scan without dye; lower brain imaging
Clinical Context
Used for evaluation of brainstem lesions, demyelinating disease, vascular accidents, and tumors. Excellent soft tissue contrast for identifying pathology without need for contrast enhancement.
