Neurology Imaging

Question 1

Cerebral Angiography

Answer 1

cerebral angiogram can detect the degree of narrowing or obstruction of an artery or blood vessel in the brain, head, or neck. It is used to diagnoze stroke and to determine the location and size of a brain tumor, aneurysm, or vascular malformation. This test is usually performed in a hospital outpatient settting and takes up to 3 hours, followed by a 6-to 8-hour resting period

Question 2

biopsy

Answer 2

muscle or nerve biopsies are used to diagnose neuromuscular disorders and may also reveal if a person is a carrier of a defective gene that could be passed on to children. A small sample of muscle or nerve is removed under local anesthetic and studies under a microscope

Question 3

Magnetic resonance imaging (MRI)

Answer 3

neurological uses include the diagnosis of brain and spinal cord tumors, eye disease, inflammation, infection, and vascular irregularities that may lead to stroke. MRI can also detect and monitor degenerative disorders such as multiple sclerosis and can document brain injury from trauma

Question 4

Positron emission tomography (PET) scans

Answer 4

PET scans of the brain are used to detect or highlight tumors and diseased tissue, measure cellular and/or tissue metabolism, show blood flow, evaluate patients who have seizure disorders that do not respond to medical therapy and patients with certain memory disorders and determine brain changes following injury or drug abuse, among other uses

Question 5

brain scan-general

Answer 5

brain scans are imaging techniques used to diagnose tumors, blood vessel malformations or hemorrhage in the brain. These scans are used to study organ function or injury or disease to tissue or muscle. Types of brain scans include computed tomography, magnetic resonance imaging, and positron emission tomograpny

Question 6

Head CT

Answer 6

head CT scans are used to view the brain and spine. They can detect bone and vascular irregularities, certain brain tumors and cysts, herniated discs, epilepsy, encephalitis, spinal stenosis (narrowing of the spinal canal), a blood clot or intracranial blleeding in patiens with stroke, brain damage from head injury, and other disorders. Many neurological disorders share certain characteristics and a CT scan can aid in proper diagnosis by differentiating the area of the brain affected by the disorder

Question 7

Myelography

Answer 7

myelograms are used to diagnose spinal nerve injury, herniated discs, fractures, back or leg pain, and spinal tumors
