X-rays produce images in different shades of black, white, and gray based on how much radiation is absorbed by different tissues in your body.

• Bones absorb the most radiation, so they appear white on an X-ray.
• Fat and soft tissues absorb less, appearing gray.
• Air absorbs the least, which is why the lungs appear black.

The type of X-ray performed (e.g., chest, abdomen, pelvis, or bones) depends on the area being examined and the medical diagnosis.

There are certain situations when you should avoid an X-ray, such as:

• Pregnancy: If you are pregnant or suspect you might be, it’s important to notify your technologist, as X-rays could potentially affect a developing fetus.
• Allergies to X-ray dye or iodine: If you’re undergoing an IVP (Intravenous Pyelogram) or other procedures that require a contrast medium, and you have an allergy to iodine or foods like shellfish, be sure to inform your healthcare provider beforehand.

An X-ray is quick and typically takes only a few minutes when no contrast is involved. If contrast is used, the procedure may take longer (up to 20 minutes or more).

• The technologist will explain the procedure, assist with the removal of jewelry or metal objects, and position you correctly to ensure the clearest possible images.
• Depending on the area being examined, you may need to lie on a table, stand, or sit between the X-ray machine and plate.
• The technologist will step into a shielded room to control the machine but will still be able to see and hear you during the procedure. You may be asked to move or adjust your position for multiple images.

While X-rays are generally safe, unprotected radiation can be harmful to those who are pregnant, growing children, and reproductive organs. At Advanced Radiology, we follow strict ALARA (As Low As Reasonably Achievable) radiation safety standards to minimize exposure.

• Pregnancy test: If there's a possibility you may be pregnant, a test should be performed before the X-ray. This ensures the safety of a developing fetus.
• Allergic reactions to contrast: If your exam requires contrast material, there is a slight risk of an allergic reaction. Most reactions are mild (itchiness or hives), but in rare cases, they may cause swelling, particularly in the throat. Be sure to inform your technologist or doctor immediately if you experience any symptoms during or after the exam.

We offer same-day, walk-in X-rays at our Columbia location between 8:00 AM and 5:45 PM, as long as we have a provider's order and the following information:

• The type of X-ray needed
• The reason for the exam

From check-in to departure, the entire process typically takes about 30 minutes, with the exam itself usually lasting less than 5 minutes.
