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?

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 D: LATERAL ELBOW Positioning:   Anatomy:   Improvements?  

Explain which view or projection should be done in place of the routine lateral if there is a known or suspected fracture of the proximal humerus:  Explain how the humerus is positioned and how it should appear on the film?  (2 pts)

Answer either true or false. If the statement is false, correct it. The amount of obliquity for an oblique hand is 30 degrees.

If the statement is true, type “true” and “false” if it is false. Correct the False Statements. (2 point each) With digital imaging, the amount of radiation reaching the IR determines the brightness of the image.

Answer either true or false. If the statement is false, correct it. The humeral epicondyles are positioned perpendicular to the IR on an accurately positioned AP humerus.
