Study notes
Question | Answer |
---|---|
diagnostic radiologist | creates images by X-rays, magnetic fields, sonar and radiocativity. Images allow the doctor to make a diagnosis of the clients disease or injury. |
radiationi oncologist | deals with the use of radiatioin i nthe treatment of cancer |
invasive imaging | requires the introduction of contrast media into various systems of the body. |
contrast media | substances that allow internal images to be reviewed. |
aniogram | an image of arteries and veins filled with contrast media |
ateriogram | an image of arteries only of contrast media |
fluroscopy | imagaing process used to guide the catheter through the artery, into the heart, and then into the coronary artery. It projects the x-ray image onto fluorescent screens |
external beam therapy | delivered in daily doses for several weeks. |
brachy therapy | involves using radionuclide sources to treat tumors inside the body. |
invasive procedures | require contrast media |
noninvasive procedures | no media required |
anaphylaxis | severe allergic reaction |
computed tomography tech. (CT or CAT) | use an x-ray machine called a computed axial tomographing scanner (CT or CAT), obtains transverse cross-sectional anatomical images of the body, can give the size, shape, and locationi of a tumor or specific organ. |
magnetic resonance tech. | use a special machine to take longitudinal and transverse cross-sectional anaatomical images of the body. MRI contains a large electromagnetic field |
Major concers for MRI | no metal present on patient, room magnetic free, claustrophobic clients find it difficult to remain in the tube. |
mammographer Papsmear | produce diagnostic images of the breat tissue with special mammography machines, use to assist in detection and treatment of breast cancer. |
radiologic technician job responsibilities | transport patients, aseptic and sterile technique and SP, explain all proccedures, operate all equipement in a clean and efficient manner |
safety factors for radiation protection | perform procedure correctly the first time to eliminate retakes, use lead shielding aprons, gloves, partitions, and blocks during exams, shuold cover reproductive organs at all time |
echocardiogram | uses sound waves to create a moving picture of the heart |
intravenous pyleogram | looks at kidneys, bladder, ureters |
sialogram | looks at salivary ducts and glands |
cystogram | looks at urinary bladder |
upper gastrointestinal exam | looks at esophagus, stomach, duodenum |
radiologic technologist | support radiologist as the perform their duties |
radiographer | high demand because of the use of radiographs for medical diagnosis |
echocaridogram | use transducer to pick up echoes of sound waves and transmit them as electrical impulses, uses echocardiography machine and transudecer |
