CAMRT Radiography Practice Exam

A patient is suspected of having a fractured ramus of the mandible. What projection routine is best for this condition?

1. Axial view

2. PA axial mandible projection

3. Axiolateral oblique projection

4. Both B and C

The correct answer is: Both B and C

To evaluate a suspected fracture of the ramus of the mandible, utilizing both the PA axial mandible projection and the axiolateral oblique projection is the most effective approach. The PA axial mandible projection specifically allows for visualization of the entire mandible, with an increased focus on the ramus. This projection is advantageous as it angles the X-ray beam to project any potential fractures more clearly, making it easier to assess the integrity of the ramus and any other associated osseous structures. On the other hand, the axiolateral oblique projection provides a lateral view of the mandible, emphasizing the ramus while minimizing superimposition from surrounding anatomical structures. This projection is particularly useful when there are suspected fractures, as it helps delineate the fracture line and assess displacement, if present. Using both of these projections in conjunction allows for a comprehensive evaluation of the condition, ensuring that any fractures in the ramus are accurately diagnosed and assessed. Thus, employing both the PA axial and axiolateral oblique projections together offers a thorough examination of the mandible, particularly beneficial in trauma cases where fractures are suspected.
