If the statement is true, type “true” and “false” if it is false. Correct the False Statements. (2 point each) On a short scale contrast radiograph, there are many useful Densities.

If the statement is true, type “true” and “false” if it is false. Correct the False Statements. (2 point each) Because overexposure of the digital image receptor typically produces an image with appropriate brightness and no quantum noise, all studies should be done with a little more exposure than needed.

Appropriate radiographic brightness:

AP SHOULDER (label the anatomy indicated on the radiographs… 1 point each): use the format below A – B – C –  

The overall quality of the radiographic image is determined by:

The degree of difference between adjacent densities is:

ELBOW (label the anatomy indicated on the radiographs… 1 point each): use the format below A –                                                           J – nothing to identify B –                                                           K –  C –                                                          L – D –                                                          M – E –                                                           N – F –                                                           O – G –                                                           P – H –  nothing to identify                           Q – I –  

A poorly positioned AP forearm image demonstrates superimposition of the third & forth metacarpal bases and the wrist demonstrates the pisiform and hook of the hamate.  How should the pt. be repositioned to obtain an optimal image?

Critique the following radiographs and determine their diagnostics quality. The following should be included in your answer: (3 points for each film) Positioning criteria: is it positioned properly? / do not state a simple yes or no – explain why it is, or how you know it is not… Anatomy included: is all anatomy included? / specifically state what anatomy is missing Improvements: explain how to make this radiograph better (be sure to use proper terminology)   Radiograph E: AP NEUTRAL SHOULDER Positioning:   Anatomy:   Improvements?    

A poorly positioned true lateral hand radiograph demonstrates the 5th metacarpal anterior to the 3rd – 4th metacarpals. How would you correct this film?
