Nervous system FINAL Flashcards
the imaging modality of choice to evaluate patients with suspected neurologic dysfunction cause by head trauma is
CT
arterial bleeding sometimes associated with head trauma can cause what kind of hematomas
epidural hematomas
venous bleeding sometimes associated with head trauma can cause what kind of hematomas
subdural hematomas
movement of the brain within the calvaria following blunt trauma to the skull sometimes results in a cerebral
contusion
bleeding into the ventricular system caused by injury to surface veins, cerebral parenchyma, or cortical arteries can cause
subarachnoid hemorrhage
plain radiographs of the facial bones should always be made with the patient in what position if possible
erect
the most common primary brain tumor is a
glioma
a benign tumor that arises from arachnoid lining cells and is attached to the dura is called a
meningioma
the most common neoplasms that metastazise to the brain arise in what 2 places
lung, breast
a viral inflammation of the brain and meninges is called
encephalitis
the best imaging modality to evaluate brain abscesses is
CT
the two imaging procedures of choice to evaluate the extent of a stroke in the brain are
CT and MRI
the acronym TIA stand for
Transient
Ischemic
Attack
the imaging modality of choice to demonstrate the plaques of demyelination that are characteristic of multiple sclerosis is
MRI
a condition in which brain impulses are temporarily disturbed, the results of which range from loss of consciousness to violent seizures, is termed
epilepsy
a diffuse form of progressive cerebral atrophy that develops at an earlier age than the senile period is called
alzheimers disease
a progressive degenerative disease characterized by involuntary tremors of the extremities that disappear with voluntary movement is named
Parkinsons disease
sinus radiographs should be taken using what kind of beam and with the patient in what position
a horizontal beam and patient in the erect position
the pathologic condition that refers to dilation of the ventricular system and is usually associated with increased intracranial pressure is
hydrocephalus
if a pt. needing facial or sinus radiographs is unable to stand or sit erect, a _________ using a _________ beam may be performed to demonstrate any air fluid levels that may be present
a cross table lateral using a horizontal beam
