General diagnostic exams may be ordered by your physician to diagnose conditions in the chest, bone, sinuses, skull or spine. Diagnostic x-ray was the first procedure developed in the field of radiology and in many ways it is still the most commonly employed form of diagnostic radiology. There is little reason to worry about the small amount of radiation an x-ray exposes you to. However, if you are pregnant, or suspect that you may be, you should tell your physician or technician before the test is performed, as special precautions may have to be taken.
