A CT scan combines a series of X-Ray imagery of a patient’s body and is used to provide medical information that is different from other imaging exams. Some people have the misconception that CT tests are dangerous due to radiation exposure but the degree of exposure is actually small. This practice test will get you ready for the CT registry, give it a try!
