Myth: All Radiation

Myth: All Radiation

1. Myth: All Radiation is bad

Fact: Radiation is all around you and is part of the natural environment in the form of radon in soil, cosmic radiation, cell phones, trace amounts found in the food and water we ingest. An average person receives 1.5 -3.5 mSv background radiation per year from natural radiation which is equal to 15 to 35 chest X rays. Imaging technologists work to ensure patients are exposed to the least amount of radiation possible during any medical imaging scan.

2. Myth: Medical Scans Can Impact Fertility

Fact: The RSNA reports that the risk to fertility for men or women from radiological imaging such as X-rays and CT scans is essentially zero, and there are no known cases of infertility caused by these exams.

3. Myth: CT scan delivers high dose.

Fact. Modern CT scan machine and HRCT protocol delivers radiation dose from 1.0 to 2 mSv which is equal to 10 to 20 chest radiograph. Important information obtained from CT scan helps clinicians to know the diagnosis as well as guide the treatment for various diseases including Covid 19.

4. Myth: Radiation can cause cancer.

Fact-Dose range relevant to radiography, some nuclear medicine and CT studies is below 10 mSv. In this range of radiation dosage there is no epidemiological data to directly support increased cancer risk. In such scenario the diagnostic information obtained from the scans outweighs the minimal amount of radiation risk.

5. Myth: You can get radioactive after x-ray or CT scan

Fact-The very nature of X-rays is to pass through the body, meaning they do not stick around in your body. As a result, you cannot expose other people to radiation after your own examination.

6. Myth: All scanning technologies have radiation.

Fact- Magnetic resonance imaging (MRI), which uses magnets rather than radiation. The magnets work with radio waves, rather than radiation, to create pictures of structures inside the body. Another non-radiation scanning technology is ultrasound. This method uses sound waves that are sent real-time to a nearby computer, which translates how the waves move through the body into images.

7. Myth: X rays are an outdated techniques

Fact- X-rays are still the most widely used diagnostic imaging procedure today, and they are also the most widely available. They provide quick results, and the technology is relatively inexpensive as compared to other types of medical imaging.
We have digital X-ray available in our department, which uses even less radiation than traditional X-ray machines and gives excellent quality for diagnostic purpose.

8. Myth: Pregnant women can’t get X -rays

Fact- During the first trimester, when the fetal organs are still developing radiation can indeed be hazardous. But if the scan is performed with necessary precautions- all dangerous can be avoided. Chest x-ray can be done with a lead proton protecting the abdomen; extremities can also be scanned freely. MRI can safely be performed in a pregnant patient, after first trimester.
