Electromagnetic radiation is a source of energy that travels through space, including light, X-rays, gamma rays, microwaves, and radio waves. It has many uses, such as sterilizing food and medical equipment, creating diagnostic imaging tests, or even treating certain diseases.

X-Ray in any format manual or digital it emits radiation but in small amount where as Ct Scan has higher than X-Ray. For patients who under go radiation therapy very frequently may have some problems with these two tests , if patient go once twice thrice in a week have not so much effects of radiation rest test like USG, MRI, EEG has nothing to do with radiations.

X-ray is a type of radiation with a large amount of electricity, used in medical imaging tests such as X-ray, computed tomography (CT scan), PET/CT or angiography and electrocardiogram. intervention. As X-rays pass through the body, the internal organs absorb part of the X-rays, the rest create images. X-rays help detect unusual health problems and diagnose certain medical conditions.

Computerized and digital x-ray equipment is utilized to produces a more detailed study of the body. X-rays are most commonly used for taking images of bones to examine injury or diagnose tumors, and are often used for visualization of the urinary and gastrointestinal systems.

A radiologist is a medical doctor (M.D.). Your radiologist is a physician who specializes in diagnosing and treating disease and injury by using medical imaging techniques.

A radiologic technologist is a specially trained medical professional that performs your diagnostic imaging examination. They do not interpret the images—that is the job of the radiologist. Each of our technologists has successfully passed a national certification examination and they also must continue their education by earning credits every year to perform imaging studies.

The length of a CT scan depends on what type of exam you hare having, and what part of your body we are scanning. A typical scan of the body, without intravenous contrast, can take about 10 minutes. If we use IV contrast, it can take about 30 minutes. If you need to take contrast, we will ask you to arrive an hour early. We will have you drink oral contrast (barium). The contrast needs to be in your system long enough to outline the gastrointestinal tract. You may need to allow extra time for your procedure in case there are delays or need for additional scans.

Intravenous contrast, also known as iodine or dye, is harmless. We use it to make it easier to see your internal organs and blood vessels. It is essential that you inform the nurse and technologist if you have any allergies. We will ask you to sign a consent form stating you understand the risks and benefits of the contrast. You may feel a warm flush sensation for a few seconds, sometimes followed by a metallic taste in your mouth. You may also get the sensation that you’re urinating on yourself, but you’re not. You might also feel itchy. If so, we can give you medication to help. A more severe reaction, while uncommon, includes difficulty breathing and swelling of the throat or other parts of the body. If this should happen, we will treat it immediately.

It is extremely important that you bring any previous pertinent studies. The radiologist needs to see how your current exam compares with previous exams. This can often eliminate the need for further studies and also helps to identify any subtle changes that have occurred since your last examination.

Wear comfortable, loose-fitting clothes. You may have to put on a gown. Metal objects like jewelry, eyeglasses, dentures, and hairpins may affect the images. When you can, leave those items at home. You may also remove them just before your exam.

Yes you can do this but better is that you contact with the disease related doctor to identify whether radiology test is required or not. Unnecessarily radio therapy or test must be avoided.
