1
Q

bone densitometry

A

a radiographic procedure to measure the mineral concentration and structure of bone. Used primarily to diagnose osteoporosis.

2
Q

cathode

A

negative electrode from which electrons are emitted.

3
Q

claustrophobia

A

fear of being confined in any space

4
Q

Doppler

A

non-invasive technique used with ultrasonography to evaluate blood flow through major arteries and veins of the arms, legs, and neck. It can reveal blood clots or blockages.

5
Q

dosimeter

A

device for measuring x-ray output

6
Q

echocardiogram

A

non-invasive diagnostic method that uses ultrasound to visualize internal cardiac structure, including valves.

7
Q

fluoroscope

A

device consisting of a screen; mounts separately or with an x-ray tube that shows the images of objects interposed between the table and the screen.

8
Q

implantable cardioverter-defibrillator (ICD)

A

implantable device used for life-threatening arrhythmias. Shocks the heart out of the arrhythmia and into a more normal sinus rhythm.

9
Q

ionizing radiation

A

X-ray beams

10
Q

isotopes

A

a chemical element

11
Q

magnetic resonance imaging (MRI)

A

method of medical imaging that measures the response of tissues to a magnetic field and radio waves resulting in images of tissues and organs of the body.

12
Q

mammogram

A

Radiographic technique that allows imaging of the breast tissue to evaluate for abnormalities.

13
Q

noninvasive

A

procedure that does not require penetrating the skin or a body opening.

14
Q

oscilloscope

A

electronic device used for recording electrical activity of the heart, brain, and muscular tissues

15
Q

osteoporosis

A

thinning of long bones, pelvic bones, and vertebrae.

16
Q

palliative

A

refers to measures taken to relieve symptoms of disease.

17
Q

positron emission tomography (PET)

A

radiographic procedure that uses a computer and a radioactive substance. The substance is injected into the patient’s body and gives off charged particles. They combine with particles in patient’s body to produce color images that reveal the amount of etabolic activity in an organ or structure.

18
Q

radioactive

A

emits rays or particles from nucleus

19
Q

radiographs

A

film on which an image is produced through exposure to x-rays

20
Q

radiolucent

A

allowing x-rays to pass through. A dark area appears on the radiograph.

21
Q

radionuclides

A

atoms that disintegrate by emitting electromagnetic radiation.

22
Q

radiopaque

A

impenetrable to x-rays. A light area appears on the radiograph.

23
Q

radiopharmaceuticals

A

radioactive chemicals used in testing the location, size, outline, or function of tissue, organs, vessels, or body fluids.

24
Q

stomatitis

A

inflammation of the mouth associated with chemotherapy. Can include swelling, redness, halitosis, and ulcerations.

25
Q

transducer

A

device that converts one form of energy to another. During an ultrasound procedure, the transducer picks up echoes and converts them to electrical energy; the energy is transformed into digitalized images that can be viewed and printed. Photographs of the image can be taken.

26
Q

X-Ray Patient Position

A
  1. Anteroposterior view: X ray directed from front toward back of body.
  2. Posterioanterior view: X ray directred from back to front of body.
  3. Lateral view: pass through from one side toopposite side.
  4. Right Lateral view: From left to right. (Right side of body next to film)
  5. Left lateral view: From right to left (Left side of body next to film)
  6. Oblique view: Positioned at an angle
  7. Supine view: Body lying face up, on back.
  8. Prone view: Body lying face down on abdomen
