QUIZ THREE

Match neurological diagnostic procedures with the correct descriptions.

1. a  ------------  X-rays are done with the contrast medium into the intracranial vessels; to visualize aneurysms, tumors, or other vascular lesions.

                                                                                                         

                                                                                                   
 1. Echoencephalography

1.  b -------------- Contrast medium is injected into the sub-arachnoid space of the spinal canal to visualize a herniated disc, tumor, or other abnormality.

                                                                                                   
 2. Cerebral angiography

1. c  --------------- Air is injected through a lumbar puncture into the sub-arachnoid space and x-rays are taken to reveal the outline of the ventricular system and sub-arachonoid cisterns.

                                                                                                        
 3. Digitalized angiography

1. d --------------- A needle puncture is made into the sub-arachonoid space between third  and fourth or the fourth and fifth lumbar vertebrae performed for various reasons.

                                                                                            
4. Computerized axial tomography

1. e --------------- X-rays are taken after the cerebrospinal fluid is substituted with air to diagnose tumors.

                                                                                                      
 5. Electroencephalography

1. f ---------------- Electric impulses emitted by the brain cells are recorded by specialized equipment for detection of abnormalities in the central nervous system. The recording is made on special paper, results from the electrodes attached on the head of the patient.

                                                                                                                      
6. Myelography

1. g --------------- Ultrasonic waves are used to detect brain tumors, hematomas, swelling or abscesses.

                                                                                                                    
7. Lumbar puncture

1. h --------------- Cerebral angiography with the computer is used to digitize the x-rays to an image on the computer screen, creates clear image of the  vessel of the brain.

                                                                                                      
 8. Pneumoencephalography

1. i ----------------Produces multiple x-rays of the brain, spinal cord, or other areas of the body in cross section.

                                                                                                                 
9. Ventriculography
