Radio - Ultrasound Of EQ

Question 1

Reasons for using ultrasound

Answer 1

Injury to flexor tendons
Radiographs fail to pick up tendons
Well established

Question 2

Strong reflection of tissue

Answer 2

Will appear white

Question 3

Weak reflection of tissues

Answer 3

Will appear grey or black

Question 4

Depth sensed on ultrasounds

Answer 4

Depth is determined by how long the wave took to travel out and back to the transducer

Question 5

High frequency

Answer 5

Leads to better resolution but shallow penetration

Question 6

Lower frequency

Answer 6

Has decreased resolution but deeper penetration

Question 7

Echogenicity

Answer 7

Appearance using shades of grey

Question 8

Anechoic

Answer 8

Darker appearances on ultrasounds
Has to do w tissue density - edema /fluid often appears anechoic

Question 9

Isoechoic

Answer 9

A similarity in adjacent shades of gray

Question 10

Hyperechoic

Answer 10

Bright appearance of tissues due to increased density

Question 11

Common preparation

Answer 11

Hair clipping
Clean area - wet /gel

Question 12

Standard equipment

Answer 12

Ultrasound machine
High frequency lines transducer
Stand-off pad

Question 13

Purpose of stand off pad

Answer 13

Creates distance for superficial structures

Question 14

Imaging technique

Answer 14

Evaluate structures individually
Scan prox to distal
Scan abnormalities in both places (transverse & longitudinal)
Limbs are weight bearing
