Q

Parasagittal plane

A

Vertical plane that divides the body into unequal right and left halves

21
Q

Coronal (frontal) plane

A

Vertical plane that divides the body into anterior and posterior portions

22
Q

Horizontal (transverse) plane

A

Plane that divides the body into superior and inferior portions

23
Q

Abduction

A

Movement away from the axis or midline of the body, or one of its parts

24
Q

Adduction

A

Movement toward the axis or midline of the body, or one of its parts

25
Q

Flexion

A

Folding movement where there is a decrease in the angle between two bones

26
Q

Extension

A

Increase in the angle between two bones; restoring a body part to its anatomical position after flexion

27
Q

Rotation

A

Movement around a vertical axis (movements of pronation/supination of the forearm)

28
Q

Plantarflexion

A

Movement of the foot at the ankle-joint extension

29
Q

Dorsiflexion

A

Movement of the foot at the ankle-joint flexion

30
Q

Inversion

A

Turning the foot so the sole faces inward or medially

31
Q

Eversion

A

Turning the foot so the sole faces outward or laterally

32
Q

Conventional radiography

A
  1. directing x-ray, detecting radiation

2. ability of substance to absorb and scatter x-rays varies with density

33
Q

Characteristics of conventional radiography

A
  1. Air filled structures are radiolucent
  2. Body fluids and tissues have similar density with fat, slightly more lucent.
  3. Bone is radio-opaque
  4. Denser the tissue, the lighter the image on the monitor
34
Q

Image directions of conventional radiography

A
  1. Posterior-anterior projection is where rays pass from posterior to anterior. Anterior-posterior is the opposite.
  2. Left lateral has rays passing through patient from left to right. Right lateral is the opposite
  3. Take at least 2 images from different directions
35
Q

Is the X-ray image more or less distorted the closer the body part is to the X-ray detector? What happens to size appearance?

A

Less distorted. The farther away from the X-ray detector the larger it appears

36
Q

Computer assisted tomography (CT)

A
  1. Multiple X-ray images rapidly performed
  2. Computer analyzes to produce images
  3. More detail than X-rays, but just as potentially harmful
  4. Use should be minimal (stronger than X rays–CT of chest=150 x-rays (in terms of radiation exposure))
37
Q

Ultrasonography

A
  1. High frequency sound waves reflected by surfaces separating structures from different densities
  2. No damaging effects
  3. Images more difficult to interpret
38
Q

Magnetic resonance imaging (MRI)

A
  1. Uses magnetic field to produce images
  2. Produces better soft tissue images than CT scan
  3. No damaging side effects
  4. Expensive, issues with claustrophobia, some patients can’t have done because of metal
39
Q

Nuclear medicine imaging

A
  1. Radioactive material injected and taken up selectively by different body organs
  2. Used to evaluate physiological function of organ or structure
40
Q

Extremity films (number and angles of films taken?)

A

AP, lateral, oblique

41
Q

What image generation test would you use to look for gallstones?

A

Ultrasound! No risk for radiation and the gallstones block the ultrasound, so nothing shows up behind them.

42
Q

What are some of the greatest uses for ultrasound?

A

Detecting pregnancy. Gallstones. Deep vein thrombosis. Best way to assess abdominal or pelvic pain in women (good at evaluating uterus and ovaries). Should be considered in checking abdominal pain in children and thin females (not enough fat can make CT hard to read)

43
Q

Is data able to be manipulated to better read CT after scan completed? MRI?

A

Yes. CT can be manipulated to view images in more than one plane. MRI cannot. You must get all the planes and images you want with the MRI before finishing the scan.

44
Q

What test is best for screening brain for acute hemorrhage and mass effect or herniation of the brain?

A

CT

45
Q

What is the best test for examining seizure foci or MS?

A

MRI

46
Q

What is the best test for ALMOST all abdominal screenings? Including PE, tumor, and interstitial lung disease?

A

CT

47
Q

Barium examinations

A

Antegrade for upper GI. Retrograde for colon. Not done nearly as often anymore, typically just do colonoscopy now or scoped from above to check the upper GI. Contrast used to determine bowel.

48
Q

PET

A

Useful in demonstrating metabolic issues in organs that appear physiologically normal. Based on the fact that tumor cells take up more glucose than normal cells. However, inflammation, infection, and healing can also be mistaken for tumor.
