Routine x-rays do not require an appointment and usually require a minimal wait time. If you are having a GI, GU or bone density test, an appointment is recommended, although walk-ins are performed between scheduled appointments but may require a longer wait.
The department is located at 6560 Fannin in the Scurlock Tower, 5th floor. Check in 10-15 minutes before the time of your appointment.
The science behind radiography involves exposing part of the body to a small dose of radiation, which produces an image of the internal organs. When the radiation penetrates the body, it is absorbed in varying amounts by different parts of the anatomy, resulting in either white or light gray images (such as the ribs and spine) or dark (such as with lung tissue).
Depending on the medium used, x-rays can be produced as film to be filed or, more commonly, as filmless computerized or digital images that can be stored electronically. Electronically stored images allow your physician to view your x-rays from his/her office.

Your x-rays are retained in General Electric’s Centricity PACS, a revolutionary picture archival communications system. Centricity stores digital images and data of patient procedures and provides immediate access to the hospital network.
Clinical images created in the Diagnostic Radiology, CT, MRI, US, Endovascular and NM departments are now available within seconds of test completion. This means faster test results and treatment for patients.
Note: In compliance with HIPAA regulations, only authorized personnel will have access to patient health care information.
