When imaging a trauma elbow that is in acute flexion, how is the central ray directed in order to image the distal humerus?
 
 perpendicular to the mid elbow joint
  perpendicular to the humerus
  perpendicular to the forearm
  angled 45 degrees towards the shoulder joint

Question 2

Excessive film drying may result in:
 
 stained radiographs
  emulsion cracking
  faded radiographs
  static discharge

Answer to Question 1

perpendicular to the humerus

Rationale: Situations of trauma elbows may present with the patient unable to fully extend the arm. Two AP projections may be acquired, one with the forearm parallel to the image receptor and the CR perpendicular to the forearm and the second with the humerus parallel to the image receptor and the CR perpendicular to the humerus. A 90 degree lateral is also taken in the most tolerable position possible.

Answer to Question 2

emulsion cracking

Rationale: The drying mechanism in automatic processing should remove the majority of moisture from the film. Excessive drying can remove all of the moisture, causing the film emulsion to crack.
