Flashcards in Intro To Ultrasound Chapt 2 Vocab Deck (47):
1

Additional controls

Imaging controls such as body pattern, Doppler, power Doppler, post web, and mode, and screen monitor controls

2

Alphanumeric keyboard

Keyboard on the ultrasound system that allows alphabetical and numerical characters to be entered for patients examination

3

Calc key

Appropriate calculations package based on imaging preset

4

Clinical applications specialist

Customizes imaging settings and measurements, demonstrates proper use of ultrasound system.

5

Help menu

Excess reference manual for alter sound system

6

HIS

Acronym for hospital information system. Electronic system that stores patient demographic information and medical records.

7

Knobology

ultrasound system controls including one primary imaging, to calculation, and three additional controls.

8

PACS

Acronym for picture archiving and communication systems. Packs enables improved image resolution as images are stored in digital format and manipulated by software controls

9

Primary imaging controls

Controls such as imaging preset, frequency, depth, and time gain compensation that directly affect image quality.

10

RIS

Acronym for radiology information system. Electronic, radiology specific network that supports imaging, reporting, and relevant patient data. This is generally a subsystem of HIS

11

Teleradiology

Radiologist consult for imaging diagnosis using packs to imbue images transmitted from Site of origin

12

Ultrasound field service engineer

Person who performs installations of ultrasound system at an imaging site

13

Ultrasound system

Software based control system for image settings and measurements

14

Assessment notes

Results of the physical examination, including a listing of patient's symptoms.

15

Differential diagnosis

Multiple pathologic conditions that may be indicated by the ultrasound findings and reported as such by the interpreting physician

16

Hepatitis B virus

Blood-borne pathogen and that requires universal precautions to reduce exposure risk. Healthcare workers can protect themselves with the hepatitis B vaccine, which requires three shots over six months and is offered at most healthcare facilities

17

HIV

Blood-borne pathogen's that required universal precautions to reduce exposure risk. Virus may lead to aids, a deficiency of the auto immune system that in many cases is terminal

18

Interpretive report

Sonologist/radiologists formal, legal, interpretive report of the ultrasound findings.

19

OSHA

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

20

Patient chart

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

21

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

Professional ultrasound organizations for sonographers and sonologists

22

Sonographer

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

23

Sonologists

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

24

Technical observation

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

25

Ultrasound request form

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

26

Universal precautions

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

Echogenic

Having many echos

28

Hyperechoic

Extremely bright and exaggerated echoes

29

hypoechoic

Low level echos

30

Anechoic

Without echos

31

Echopenic

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

32

Isoechoic

Two structures having the same echogenicity

33

Sonolucent

A cystic or fluid filled structure

34

Homogenous

Echo pattern smooth and even

35

Heterogeneous

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

36

Posterior enhancement/thru transmission

Characteristic of structures containing fluid

37

Shadowing

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

Refraction

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

Reverberation

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

Comet tail/ring down

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

41

Side lobe artifact

Slice thickness artifact

Can make a fluid filled structure appear filled with sludge.

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

42

Mirror Artifact

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

43

Split image

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

Propagation velocity

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

Cyst features

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

46

Solid mass features

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

47

Complex mass

Both cystic and solid features. May be septated
