are dexa scans bad for you?

How safe are bone density (DEXA) scans. Bone density scans are very safe. They use a much lower level of radiation than standard X-rays, which means that the radiographer (the technical specialist carrying out the scan) can stay in the scanning room with you during the scan.

The scanner bounces waves off your body which then go back to the machine for processing. The level of radiation you're exposed to during this process is lower than you get from your phone. At these low levels, exposure is considered safe for everyone, including pregnant women.

There are no risks associated with MRI scans. They are painless and generally quick with no lasting effects. The scanner does not touch your child during the scan. MRI scans are not suitable for people with certain metal implants inside them (such as pacemakers) because the scanner emits a strong magnetic field.

Cardiac CT scans have some risks. In rare instances, some people may have an allergic reaction to the contrast dye. There is a slight risk of cancer, particularly in people younger than 40 years old, because the test uses radiation.

Our CT scanners keep radiation doses as low as possible while still obtaining high-quality images. But in reality, the amount of radiation from a single imaging test really is not that much. In general, the benefits of imaging tests far outweigh the radiation risks.

It is said that tests and early treatment can help with early detection and allow a person to get the proper form of treatment. However, as it turns out, imaging scans such as digital x-rays may result in a false positive result, where imaging results look like cancer, but may not be at all.

Avoid food and drinks that contain sugar or carbohydrates for at least 24 hours before your scan. This will help to make sure that your images are of the best quality and help prevent having to reschedule your scan because of a blood sugar that is too high.

If you are given contrast by mouth, you may have diarrhea or constipation after the scan. Otherwise you don't need any special care after a CT scan of the abdomen. You may go back to your usual diet and activities unless your healthcare provider tells you differently.

Dental X-ray exams are safe; however, they do require very low levels of radiation exposure, which makes the risk of potentially harmful effects very small.

Chest CT scans have some risks. In rare instances, some people have an allergic reaction to the contrast dye. There is a slight risk of cancer, particularly in growing children, because the test uses radiation.

A three-phase bone scan is a nuclear imaging test that shows how the bones process an injected agent. A DEXA bone scan is a type of X-ray that tests bone strength and density to diagnose osteoporosis.

Follow a special diet for 12 to 24 hours before the scan. Don't drink or eat anything, except water, for 6 hours before the scan.

Risks. In general, X-rays are very safe. Although there's some minor risk to the body with any exposure to radiation, the amount of radiation used in an abdominal X-ray is small and not considered dangerous.

DXA Scan Results The lower your score, the weaker your bones are: T-score of -1.0 or above = normal bone density. T-score between -1.0 and -2.5 = low bone density, or osteopenia. T-score of -2.5 or lower = osteoporosis.

Takeaway. Both CT scans and MRI scans are relatively low risk. Both offer important information to help your doctor properly diagnose specific conditions. Most likely, your doctor will tell you which one they recommend.

They're generally painless and don't require needles, shots or cuts. You aren't exposed to ionizing radiation, so the procedure is safer than X-rays and CT scans. In fact, there are no known harmful effects when it's used as directed. Ultrasound captures images of soft tissues that don't show up well on X-rays.

A bone density scan uses low dose X-rays to see how dense (or strong) your bones are. You may also hear it called a DEXA scan. Bone density scans are often used to diagnose or assess your risk of osteoporosis, a health condition that weakens bones and makes them more likely to break.
