Hand X-Ray

How does a hand X-ray work?

X-rays are a type of radiation. Small beams of radiation pass through your body and produce an image on special photographic film or a detector.

Your body parts absorb different degrees of radiation. Your bones are dense and filled with calcium, so they appear white on X-rays. Muscle, fat and organs are less dense and let more radiation through, so they appear varying degrees of gray. Air appears black.

How do I prepare for a hand X-ray?

Hand X-rays don’t need much preparation. Before the test, you’ll be asked to remove all jewelry from your hand and wrist. Jewelry may interfere with the X-ray images.

It’s important to tell your radiologic technologist if you’re pregnant or if there’s any possibility you might be pregnant. The amount of radiation used for a hand X-ray is minimal and considered safe during pregnancy. But your healthcare provider will decide if an X-ray is necessary. Your technologist will use precautions to reduce radiation exposure to the fetus.

Before your X-ray, your radiologic technologist will explain the procedure to you and answer any questions you have.

What can I expect during a hand X-ray?

A radiologic technologist will perform your hand X-ray in your healthcare provider’s office or a hospital radiology department. Once in the X-ray room, you may be given a lead apron to protect your reproductive organs from radiation exposure. The X-ray room may be cold, but the whole test usually only takes five to 10 minutes. The procedure itself is painless — you won’t feel the radiation.

The technologist will have you place your hand on the X-ray table. Sponges, sandbags, pillows or other equipment may be positioned around your arm to keep it from moving during the X-ray. It’s important to keep very still during the test because movement can blur the X-ray images. You may be asked to hold your breath for a few seconds while the images are being taken.

Your technologist will place an X-ray film holder or digital recording plate under the X-ray table. Then they’ll go into a small room or behind a wall to operate the X-ray machine. You may be asked to turn your hand and hold various positions so images can be taken from multiple angles. You also may be asked to hold sandbags or other devices to show what the area being studied looks like when it bears weight. Two or three images from each angle will be taken. Let your technologist know if you’re in any pain. They’ll find ways to assist you through the test.

What can I expect after a hand X-ray?

After your hand X-ray, your radiologic technologist may ask you to wait a few minutes while they take a quick glance at the images. They want to make sure none of the images are blurry before letting you go. If any of the images are blurry, they’ll retake them.

After that, a doctor called a radiologist will review the images. Radiologists are trained to analyze X-ray images and interpret the results. Once the radiologist has reviewed the results, they’ll send them to your healthcare provider. Your healthcare provider will discuss the findings with you and recommend appropriate treatment.

Depending on the results, you may be asked to return for a follow-up exam. Your healthcare provider may want additional X-ray images for different views of your hand. You may also be asked to return to track your condition and see if any changes have occurred over time.

What are the risks of a hand X-ray?

X-rays provide a fast and easy way for your healthcare provider to diagnose medical conditions in your hand or hands. The amount of radiation exposure in a hand X-ray is minimal. The radiation passes right through you. X-rays usually don’t cause any side effects.

People who are pregnant have a slightly higher risk of problems with radiation exposure. They should always tell their radiologic technologist if they’re pregnant or think they could be pregnant. You may wear a lead apron to protect certain parts of your body from radiation exposure. Children have a slightly higher risk as well. Lower amounts of radiation may be used on children.

Excessive exposure to radiation carries a slight risk of cancer. However, all healthcare providers agree the benefit of an accurate diagnosis outweighs the risk of radiation exposure. If you’re concerned about the amount of radiation you’ll be exposed to, ask your healthcare provider.
