Q

OSHA

A

And agency within the United States Department of Labor. OSHA standards are designed to protect healthcare workers from major blood borne diseases.

20
Q

Patient chart

A

Compilation of patient information, including medical history, results of physical exam, patient symptoms, and laboratory test results

21
Q

Society for diagnostic medical sonography and American Institute of ultrasound in medicine

A

Professional ultrasound organizations for sonographers and sonologists

22
Q

Sonographer

A

Ultrasound professional responsible for performing and recording ultrasound studies for phys interpretation

23
Q

Sonologists

A

Position responsible for providing the final, legal, interpretive report may include differential diagnosis of ultrasound findings.

24
Q

Technical observation

A

Sonographers written summary of the ultrasound findings using sonographic terminology. Never a diagnosis, as it is not considered justified or legal

25
Q

Ultrasound request form

A

Patient identification data, clinical symptoms, and examination request and why.

26
Q

Universal precautions

A

Treating all patients as if they may have HPV/HIV or other blood borne diseases, meaning that engineering, workplace, and housekeeping controls are in place to ensure safety.

27
Q

Echogenic

A

Having many echos

28
Q

Hyperechoic

A

Extremely bright and exaggerated echoes

29
Q

hypoechoic

A

Low level echos

30
Q

Anechoic

A

Without echos

31
Q

Echopenic

A

A mass which has low level echos- but is less echogenic then the surrounding tissues

32
Q

Isoechoic

A

Two structures having the same echogenicity

33
Q

Sonolucent

A

A cystic or fluid filled structure

34
Q

Homogenous

A

Echo pattern smooth and even

35
Q

Heterogeneous

A

Indicates an irregular or uneven pattern which may appear to have mixx echogenicities

36
Q

Posterior enhancement/thru transmission

A

Characteristic of structures containing fluid

37
Q

Shadowing

A

Opposite of posterior enhancement. Due to:

  1. Tissue is so dense or completely absorbs sound.
  2. Reflects sound like air/gas.
  3. Result if refraction/bending the sound beam
38
Q

Refraction

A

Bending the sound beam. Can result in shadowing. This is when echoes are not received by the transducer, and therefore cannot be compressed and shown on the monitor.

39
Q

Reverberation

A

A type of artifact caused by the sound bouncing off a highly reflective interface- freq seen when fluid filled structures are near the transducer.

40
Q

Comet tail/ring down

A

A specific type of reverberation artifact caused by a strong air interface (like the trachea) and appears as multiple spiral, parallel lines

41
Q

Side lobe artifact

Slice thickness artifact

A

Can make a fluid filled structure appear filled with sludge.

CAN BE ELIMINATED!
Adjust focal zone/depth
Change frequency
Change transducer

42
Q

Mirror Artifact

A

Occurs when the sound beam hits a curved structure. Produces mirror image directly behind orig reflector. Diaphragm is known for this

43
Q

Split image

A

Type of artifact. Caused by refraction of sound as it travels thru abdominal muscles. Causes duplicate image NEXT to the reflector.

CAN BE ELIMINATED!

Change transducer position

44
Q

Propagation velocity

A

Type of artifact that causes mis registration of information due to changes in velocity as it passes through different densities. If the sound is delayed, it recorded as positioned deeper then expected.

45
Q

Cyst features

A

A specific type of mass. Must meet these criteria.
1- well defined borders
2-no internal echoes
3-posterior enhancement

46
Q

Solid mass features

A
  1. Irregular borders
  2. Multiple internal echoes
  3. NO posterior enhancement
47
Q

Complex mass

A

Both cystic and solid features. May be septated
