Fingers & Hand

Question 1

What should be clearly seen in the evaluation criteria for imaging digits 2-5?

Answer 1

Evidence of proper collimation and presence of side marker placed clear of anatomy of interest

Proper collimation ensures that the image captures only the area of interest, reducing unnecessary exposure and improving image quality.

Question 2

What is the required positioning of the digit in imaging?

Answer 2

Entire digit from fingertip to distal portion of the adjoining metacarpal

This ensures complete visualization of the digit and its relationship with adjacent structures.

Question 3

What should be avoided to ensure clarity in imaging?

Answer 3

No soft tissue overlap from adjacent digits

Overlapping soft tissues can obscure important details and lead to misinterpretation.

Question 4

What indicates that there is no rotation in the imaging of digits?

Answer 4

Equal concavity on both sides of the phalangeal bodies

This ensures that the digit is properly positioned and not rotated, which is crucial for accurate assessment.

Question 5

What should be equal on both sides of the phalanges in imaging?

Answer 5

Equal amount of soft tissue on both sides of the phalanges

This indicates proper alignment and positioning of the digit during imaging.

Question 6

Where should the fingernail be centered in an imaging evaluation?

Answer 6

Centered over the distal phalanx

Centering the fingernail provides a visual reference for proper positioning of the digit.

Question 7

What joint spaces should be open in the imaging of digits?

Answer 7

Open IP and MCP joint spaces

Open joint spaces are essential for assessing joint health and potential injuries.

Question 8

What detail should be visible in the imaging of digits?

Answer 8

Bony trabecular detail and surrounding soft tissues

This detail helps in evaluating the integrity of the bone and associated soft tissues.

Question 9

True or False: Digits that cannot be extended can only be examined in whole sections.

Answer 9

False

Digits that cannot be extended can be examined in small sections for better assessment.

Question 10

What type of projection is recommended when joint injury is suspected?

Answer 10

AP projection instead of a PA projection

The AP projection may provide a clearer view of the joint and surrounding structures in cases of suspected injury.
