CH 1 Flashcards
Bone densitometry (BD)
Measurement of bone density, using Joel energy x-ray absorptiometry to detect osteoporosis
Cardiac and vascular interventional radiology (CI)
Radiologic procedures for the diagnosis and treatment of diseases of the cardiovascular system
- uses x-rays to visualize human blood vessels and heart anatomy
- Requires use of catheter and contrast
Computer tomography (CT)
Recording of predetermined plane in the body using an x-ray beam, that is measured, recorded, and then process by computer for display on a monitor
Diagnostic medical sonography
Visualization of deep structures of the body, by recording the reflection of pulses of ultrasonic waves directed into the tissue
Echocardiography
Ultrasound image of her and associated vasculature
Energy
Capacity to operate or work
ionization
Any process by which a neutral atom gains or loses an electron creating a net charge
Medical resonance imaging (MRI)
Process of using a magnetic field and radio frequencies to create sectional images of the body
Mammography
Radiography of the breast
Nuclear medicine technology
Branch of radiology that involves introduction of radioactive substances into the body for both diagnostic and therapeutic purposes
Positron emission tomography (PET)
Creation of sectional images of the body, that demonstrate the physiologic function of various organs and systems
Radiation
Energy transmitted by waves through space or through medium
Radiation therapy
Branch of radiology involved in the treatment of disease by means of x-rays or radioactive substances
Radiography
Making of records of internal structures of the body by passing x-rays or gamma rays through the body to act on specially sensitized film, or imaging plate or system
Radiologic technologist (RT)
General term applied to an individual who performs radiographic, radiation, therapy, or nuclear medicine technology
Radiologist
Physician who specializes in the use of x-rays and other forms of both ionizing, and non-ionizing radiation in a diagnosis and treatment of disease
Radiologist assistant (R.A.)
In advanced level radiographer, who extensive capacity of the radiologist in the diagnostic imaging environment, enhances patient care
Radiology
Branch of the health sciences, dealing with radioactive substances and radiant energy and with diagnosis and treatment of disease, by means both of ionizing and non-ionizing radiation
Roentgen Ray
Synonym for x-ray
x-ray
Electromagnetic radiation of short wave links that is produced when electrons move at high velocity are suddenly stopped
Explain the use of radiation in medicine
Different types of imaging
give an overview of the history of medicine
- Prehistoric skulls found in Europe and South America demonstrate early human deliberately removing bone from skull successfully
- Potent drugs, castor oil and opium, were used in ancient Egypt
- Hippocrates is the father of Western medicine and he emphasized the importance of carefully observing the patient , how nature can heal over time, and prevention of disease through diet and exercise, high standard of ethical conduct
- Romans recognized importance of proper sanitation
- 17th century: William Harvey (English physician) first, to demonstrate the function of the heart and circulation of blood, Anton van Leeuwenhoek (dutch zoologist) described bacteria
- 18th century: surgery started happening, mental health reforms, Edward Jenner (English physician) introduced a vaccine to prevent smallpox
- 19th century: theory that germs cause disease was established, Louis Pasteur (French chemist) proved germ theory of infection, Robert Koch (German bacteriologist), establish bacterial cause for infection, Florence nightingale develop foundations for modern nursing, Rontgen discovered xrays
- 20th century: development of the scientific method, sir Alexander Fleming, discovered penicillin, Clark and Watson identified DNA, human genome project completed in 2003
Give an overview of radiologic technology history
November 8, 1895: wilhem roentgen, German physicist, been experimenting with cathode rays and exploring their properties outside glass tubes, was using a crooks tube and saw that a screen that had been painted with barium was emitting light
1970s imaging at further advanced to include sonography, CT, MRI
1901: won Nobel prize
