When performing an MRI to confirm a suspected pituitary microadenoma, contrast is
injected and imaging is performed:
A. With fat suppression to better visualize the lesion-gland contrast
B. With delayed imaging because lesions enhance slower than the pituitary gland
C. Rapidly because lesions enhance before the pituitary gland

pituitary gland - Answer- D. Rapidly because lesions appear as low signal intensity
compared to the enhanced pituitary gland
When performing an MRI to confirm a suspected pituitary microadenoma, contrast is
injected and imaging is performed rapidly because lesions appear as low signal
intensity compared to the enhanced pituitary gland.

Which cranial nerve is responsible for Bell's Palsy?
A. Cranial nerve VII (the facial nerve)
B. Cranial nerve VIII (vestibulocochlear nerve)
C. Cranial nerve XII (hypoglossal nerve)
D. Cranial nerve X (vagus nerve) - Answer- A. Cranial nerve VII (the facial nerve)
Bell's palsy is a form of facial paralysis resulting from a dysfunction of the cranial nerve
VII (the facial nerve) that results in the inability to control facial muscles on the affected
side
,The right and left optic nerve join at the:
A. Optic chiasm
B. Foramen magnum
C. Transverse sinus
D. Internal optic canals - Answer- A. Optic chiasm
____________ is a condition in which part of the cerebellar tonsil is displaced through
the foramen magnum.
A. Hydrocephalus
B. PRES
C. Cavernous Angioma
D. Chiari Malformation - Answer- D. Chiari Malformation
Arnold-Chiari malformation, or often simply Chiari malformation, consists of an inferior
displacement of the cerebellar tonsils through the foramen magnum
A FLAIR sequence with a long TI is utilized to:
A. null the signal from fat
B. null the signal from CSF
C. null the signal from white matter
D. enhance the signal from flowing blood - Answer- B. null the signal from CSF
FLAIR (Fluid Attenuated Inversion Recovery) is used to null CSF signals, yielding an
image sensitive to white matter lesions
The dural venous sinuses that drain into the internal jugular vein are the:
A. Sigmoid sinus
B. Superior sagittal sinus
C. Inferior sagittal sinus
D. Transverse sinus - Answer- A. Sigmoid sinus
Which dural venous sinuses drain from the confluence of sinuses (by the internal
occipital protuberance) to the mastoid portion of the temporal?
A. Superior sagittal sinus
B. Transverse sinuses
C. Ethmoid sinuses
D. Sigmoid sinuses - Answer- B. Transverse sinuses
The transverse sinuses drain from the confluence of sinuses (by the internal occipital
protuberance) to the sigmoid sinuses (mastoid portion of the temporal)
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
A. Orbits/Optic Nerves
, B. Internal auditory canals
C. Pituitary gland
D. Cerebellar Tonsils - Answer- A. Orbits/Optic Nerves
Globe tumor of the Orbits can be associated with symptoms of diplopia (double vision)
_______ sequences are performed to suppress CSF (cerebro-spinal fluid)and aid in the
detection of demyelination.
A. T1 weighted
B. STIR
C. T2 weighted
D. FLAIR - Answer- D. FLAIR
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.
A. Pituitary gland
B. Orbits/Optic nerves
C. Internal Auditory Canals
D. Thyroid Gland - Answer- C. Internal Auditory Canals
A vestibular schwannoma, often called an acoustic neuroma, is a benign primary
intracranial tumor of the cells of the vestibulocochlear nerve (CN VIII), located in the
Auditory Canals
Which fissure divides the frontal and parietal lobes from the temporal lobes?
A. Salty fissure
B. Sylvian fissure
C. Anterior fissure
D. Longitudinal fissure - Answer- B. Sylvian fissure
The __________________ runs the length of the falx cerebri.
A. Frontal sinus
B. Transverse sinus
C. Sigmoid sinus
D. Superior sagittal sinus - Answer- D. Superior sagittal sinus
The superior sagittal sinus (also known as the superior longitudinal sinus), within the
human head, is an unpaired area along the attached margin of falx cerebri. This sinus
runs the length of the falx cerebri.
If the third ventricle is dilated, but the fourth ventricle is not, there would then be
pathology associated with:
A. Insular cortex
B. Basal ganglia
C. Aqueduct of Sylvius
D. Lateral ventricles - Answer- C. Aqueduct of Sylviu
