A lumbar puncture is also known as a:
|
During a lumbar puncture procedure, cerebrospinal fluid (CSF) is withdrawn from the spinal cavity using a needle directed into the subarachnoid space. The CSF is withdrawn for laboratory analysis. Lumbar puncture, also called a spinal tap, may also be used to administer antibiotic medications to treat meningitis.
|
|
|
The ER physician suspected Baby Chang had meningitis and performed a lumbar puncture to obtain ________spinal fluid for analysis.
|
A lumbar puncture is performed in various therapeutic and diagnostic procedures, including withdrawal of cerebrospinal fluid (CSF) for analysis. Cerebrospinal fluid flows through and protects the four ventricles of the brain (cerebr/o = cerebrum), the subarachnoid space, and the spinal canal.
|
|
|
_____________ is the radiographic imaging of the blood vessels in the brain after injection of contrast medium.
|
Blood vessel = angi/o and brain (cerebrum) = cerebr/o. Cerebral angiography uses a contrast medium to visualize the arterial blood vessel system in the brain.
|
|
|
Electro________ is the recording of the electrical activity of the brain.
|
electr/o refers to the electrical activity mentioned in the question, the suffix -graphy = process of recording, and encephal/o = brain. Electroencephalography reveals seizure activity resulting from brain tumors, diseases, or trauma.
|
|
|
A _____________ scan, which is abbreviated ___ scan, is a computerized imaging technique that shows chemical activity of the brain and gives information about brain function.
|
Positron emission tomography (PET) uses radioactive glucose to image chemical (metabolic) activity of cells.
|
|
|
The procedure in which CSF is withdrawn for analysis from between two lumbar vertebrae is:
|
A lumbar puncture is a surgical procedure that uses a needle to puncture a space between two lumbar vertebrae for the purpose of withdrawing cerebrospinal fluid (CSF) for laboratory analysis.
|
|
|
The imaging modality that generates computerized multiple images of the brain and spinal cord using a contrast material is:
|
In the case of computed tomography (CT) of the brain, multiple computerized images of the brain and spinal cord are taken while contrast material is allowed to leak through the blood-brain barrier from the vessels into the brain.
|
|
|
_____ is a computerized imaging technique that shows the chemical activity of the brain.
|
Positron emission tomography (PET) uses radioactive glucose injected into the brain to image the chemical (metabolic) activity of brain cells. This diagnostic procedure can detect malignancy and evaluate brain abnormalities in Alzheimer disease, stroke, schizophrenia, and epilepsy.
|
|
|
This imaging study uses sound waves to detect blood flow in the carotid and intracranial arteries.
|
The carotid artery carries blood to the brain. Doppler ultrasound studies use sound waves to detect blood flow in the carotid and intracranial arteries and can detect occlusion in the blood vessels.
|
|
|
During __________ radiosurgery, a focused beam of radiation, called a(n) _________, can target a tumor to destroy it.
|
Stereotactic radiosurgery is the use of a specialized instrument to locate and treat neoplasms in the brain. The stereotactic instrument is fixed onto the skull to locate the tumor.
|
|
|
Treatment of hydrocephalus involves the use of a __________ to drain the excess cerebrospinal fluid.
|
To relieve pressure in cases of hydrocephalus, a shunt can be placed from the ventricle of the brain into the peritoneal space or right atrium of the heart so that the CSF is continuously drained from the brain.
|
|
|
Which of the following diagnostic procedures uses a magnetic field and pulses of radiowave energy to image the brain and spinal cord?
|
Magnetic resonance imaging (MRI) uses a magnetic field and pulses of radiowave energy to create images of the brain and spinal cord.
|
|
|
Which of the following is a procedure to diagnose abnormal electrical activity of the brain?
|
Electroencephalography (EEG) records the electrical activity of the brain. EEG can demonstrate seizure activity resulting from brain tumors and other diseases as well as injury to the brain.
|
|
|
Which of the following is a procedure that uses radioactive material that is taken up by the brain to gather information about the brain?
|
With positron emission tomography (PET), radioactive glucose is injected and taken up into the brain where it can be detected with images that record the metabolic activity of brain cells.
|
|
|
Preferred imaging technique for viewing brain damage related to infection, inflammation or tumors:
|
Magnetic resonance imaging (MRI) uses a magnetic field and pulses of radiowave energy to create images of the brain and spinal cord. MRI is better than CT at evaluating brain parenchyma. MRI is excellent for viewing brain damage related to infection, inflammation, or tumors. MRI is used to look for causes of headaches, to help diagnose a stroke, and to detect bleeding.
