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 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 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? frontal lobe and/or temporal lobe
