Has your wrist suddenly started hurting? Maybe it was from a fall. Or is there swelling or pain that has been going on for a while? When you go to see a doctor at a time like this, it's very likely that they'll say, 'Let's take an X-ray of your wrist.' So today, let's talk about what this so-called wrist X-ray is, what it finds, and whether you should be afraid of it.
Simply put, what is a wrist X-ray?
A wrist X-ray is a test that takes a picture of what's inside your wrist. To be precise, it's like a 'photograph' using a special type of radiation (electromagnetic waves) that are invisible to our eyes and can pass through the body.
Imagine, inside our wrist there are different things like bones, muscles, and fat. When the X-ray beam passes through the body, the amount of radiation absorbed by each of these parts is different.
- Bones: Because our bones contain more calcium, they absorb more radiation. That's why bones appear white on an X-ray.
- Soft Tissues: Things like muscle and fat absorb less radiation, so they appear as varying shades of gray .
This way, the doctor can clearly see the shape of the bones inside your wrist, how they are positioned, and whether there is any damage to them. The two bones in your arm (the radius and ulna) and the eight small bones in your wrist (the carpal bones) can be seen clearly in this image.
In what situations is it advisable to take a wrist X-ray?
A wrist X-ray is the main reason a doctor will recommend a wrist X-ray to find the cause of pain, swelling, or tenderness in your wrist. There are several conditions that can be diagnosed with this. Let's take a look at what they are.
| Recognizable condition | A simple explanation |
|---|---|
| Fractures | You can check to see if a bone in your wrist has been broken or sprained, such as from a fall. |
| Dislocated joints | This helps to confirm that a wrist joint has been displaced from where it should be. |
| Conditions such as arthritis | Look at the damage to the bones caused by conditions such as joint pain and joint swelling that have been present for a long time. |
| Carpal tunnel syndrome | Check for any changes in the bones related to this condition. |
| Bone cysts | Identify things like fluid-filled cysts that form inside bones. |
| Bone Infection (Osteomyelitis) | If there is a suspicion that a germ has entered the bones and caused an infection. |
| Bone cancer | This is a very rare occurrence, but if the doctor has any doubts, he or she may perform this test. |
In addition, there are other opportunities.
- Track the progress of your treatment: Imagine you broke your wrist and had a cast put on it. After a while, you'll get an X-ray to see if the bones are properly aligned and healing.
- Check your child's growth: Sometimes, if a pediatrician thinks there is a problem with a child's growth, they will take an X-ray of the wrist to check the child's "bone age." This can help determine if there is a medical condition that is affecting the child's growth.
What happens before and during the X-ray?
This process is very simple. There's nothing to think about.
Who is doing this?
A wrist X-ray is taken by a radiologic technologist (`(Radiologic technologist)`). We usually call them X-ray technicians. They are people who have received special training for this purpose.
How should I prepare?
No special preparation is required, but keep these things in mind.
- Remove all jewelry from your hands and wrists. Items like watches, bracelets, and rings can show up on the X-ray image and interfere with an accurate diagnosis.
- If you are pregnant or suspect you are pregnant, be sure to tell the technologist. A wrist X-ray emits very small amounts of radiation, so it is considered safe during pregnancy, but it is important to let them know. This will allow them to take special precautions to minimize radiation exposure to the fetus.
What to expect when taking an X-ray?
The entire process should take no more than 15 minutes. The room where the X-ray is taken is usually a bit cold. Control the temperature of that X-ray machine.
You won't feel any pain. You won't even feel the radiation beam passing through your body.
The technologist will ask you to place your hand on the X-ray table. You may be given something like a sponge to hold your wrist in place. It is very important to stay still during the X-ray , as moving can blur the image.
Usually, at least two X-ray images of the wrist are taken. One with the hand turned upwards (posteroanterior view), and the other with the hand turned to the side (lateral view). Sometimes a picture may be taken with the hand tilted (oblique view). Just like taking a photograph, it is looked at from not just one side, but from several sides to find out exactly what is wrong.
What happens after the X-ray is taken?
After the X-ray is taken, you will be asked to wait a while while the technologist checks to see if the images are clear. If any of the images are unclear, they may need to be retaken.
Then, a doctor who is specially trained to analyze these X-ray images, called a radiologist, carefully studies the images. He or she writes a report about what they found on the images and sends it to your doctor. Your doctor will then review the report, explain your condition, and discuss any treatment options you may need.
In the event of an emergency (for example, at the ETU), the X-ray results can be known almost immediately. In normal cases, the results are available within a day or two.
Is there a risk in this? What else should you know?
An X-ray is a great way to diagnose diseases quickly and easily.
The amount of radiation from a wrist X-ray is very low, so there's no need to worry too much about it. A doctor will recommend this test because the benefits far outweigh the very small risks.
Although excessive exposure to radiation can pose a risk of cancer, the amount received from a single wrist X-ray is not enough to pose that much of a risk. If you have any doubts about this, you can talk to the technologist.
Can an X-ray show a sprain?
This is a problem that many people have. X-rays mainly show bones. A sprain is an injury to the ligaments (ligaments). These ligaments are soft tissues and do not show up clearly on an X-ray.
However, even if a doctor suspects a sprain, they will take an X-ray to make sure there is no fracture. Sometimes, if the small bones in the wrist are out of alignment, such as if they are too far apart or have moved over each other, this can be a sign that the ligaments have been damaged. If they need to look at the ligaments themselves, your doctor may recommend another test, such as a CT scan or MRI scan.
Take-Home Message
- A wrist X-ray is a simple, painless test to look at the bones inside your wrist.
- This helps to diagnose many conditions such as fractures, sprains, and arthritis.
- The amount of radiation from this is very low, so it is generally safe.
- If you are pregnant or suspect you are, be sure to tell your doctor before having the X-ray.
- Before the test, remove all jewelry such as watches, bracelets, and rings.
- Your doctor will explain the final results and any necessary treatments to you.
