ARRT MRI exam study guide
If a brain exam is being performed and the request is made to rule out acoustic neuroma, a
protocol with thin cuts through the _________ should be performed.
Inner auditory canals
The _____________ imaging plane would be the most optimal slice orientation for
evaluation of Arnold Chiari Malformation and its inferior cerebellar tonsillar herniation.
sagittal
A FLAIR sequence with a long TI is utilized to:
null the signal from CSF
If a brain exam is being perfomed and the request is made to rule out microadenoma due to
elevated prolactin levels, a protocol with thin cuts through the ____________ should be
performed.
pituitary gland
If a brain exam is being perfomed and the request is made to rule out globe tumor due to
symptoms of diplopia, a protocol with thin cuts through the ____________ should be
performed
orbits/ optic nerves
We have an expert-written solution to this problem!
MR findings of a low volume corpus callosum and increased white matter lesions can be
indicative of a diagnosis of:
multiple sclerosis
If a brain exam is being performed and the request is made to evaluate cranial nerves VII
and VIII due to the patient's symptoms of tinnitus, a protocol with thin cuts through the
____________ should be performed.
Inner Auditory Canal
How many cranial nerves are there?
12 pairs
, To best visualize the pituitary gland in MRI, high resolution T1 weighted images in the
__________ planes pre and post contrast are optimal.
sagittal and coronal
____________ is a condition in which part of the cerebellar tonsil is displaced through the
foramen magnum.
chiari malformation
We have an expert-written solution to this problem!
When imaging a hemorrhagic infarct in the brain, which pulse sequence would demonstrate
the magnetic susceptibility effects better?
gradient echo

_______ sequences are performed to suppress CSF (cerebro-spinal fluid)and aid in the
detection of demyelination.
FLAIR
The brainstem includes what?
midbrain, pons, medulla oblongata
On a T2 weighted image, CSF appears bright because it has a __________ relaxation time.
long T2
Which area(s) of the brain is/are typically affected in patients with a history of epilepsy?
