When taking an equine cervical vertebrae radiograph, there are 3 areas we discussed in lecture. Name an area, the corresponding cervical vertebrae included in the shot and identify the vertebrae the beam should be centered over for that “area’s” view.
Area 1 (skull base): C1-3; center C2
Area 2: C3-5; center C4
Area 3: C5-7; center C6
