CT Protocols Practice Quiz

The next in-class quiz will be given on Thursday, April 9, 2009.

The questions will be presented in several formats: short answer, fill in the blanks, identification of anatomy, etc.

This practice quiz is a good indication of what to expect:

1. Regarding upper extremity trauma, in what areas or procedures does CT imaging improve on the capabilities of conventional radiography.

3. What is being demonstrated in the region circled below?

4. The image below was produced by a post-processing technique called ______________ rendering.



5. The image below shows a humeral CT scan of a pediatric patient. The fracture shown is in the region of the ______________ plate.



6. List six indications for CT evaluation of pediatric trauma patients.

7. What is an occult fracture?

8. What is an intra-articular fracture?

9. What result of patient trauma is being demonstrated in the image below?



10. Below, the arrow is pointing to a fracture of the ________________.



11. In musculoskeletal imaging MDCT has proven to be much more reliable at showing fractures than conventional radiography. Is this statement true or false? Give evidence from the presentation to justify your answer.

12. What are the consequences of an undiagnosed fracture?

13. List three reasons for CT examination of the tibial plateau?

14. The avulsion shown in the image below, is in the region of the tibial ______________.



15. What is the name of the major blood vessel shown in the CT angiogram?



16. The image below shows a fracture of the _______________.


17. There are two fractures shown in the image below, what are the specific anatomic regions where these fractures are located?


18. In the case of arterial injuries, what are the findings that are of interest to the radiologist based on CT angiogram studies.

19. Regarding CTA of the extremities, what are some of the pitfalls that may lead to sub-optimal studies?

20. Based on the statement below, what is meant by sensitivity and specificity when used in this context?
