The risk of side effects of an X -ray while you are pregnant is extremely minimal, but it is always important to protect the developing fetus from harm. X -ray examinations of areas of the body including the arms, legs, chest, head, or teeth do not expose your reproductive organs or your unborn child to a direct X -ray beam.
If there is a radioactive isotope used, your doctor may recommend you stop breastfeeding for a short time. Computed tomography (CT) scans combine X -ray with computer processing to create detailed pictures (scans) of cross-sections of the body that are combined to form a three-dimensional X -ray image.
Cardiac angioplasty uses fluoroscopy with a contrast agent to guide an internally threaded catheter to help open clogged arteries. Fluoroscopy is also used to precisely place instruments in certain locations within the body, such as during epidural injections or joint aspirations.
You may be asked to remove any metal objects such as eyeglasses, jewelry, or watches that may interfere. If you are getting an X -ray with contrast such as barium or iodine, you may be given a liquid to swallow, an injection, or enema with the agent prior to the X -ray.
If you are getting an X -ray of your gastrointestinal tract you may be told not to eat or drink anything for 8 or more hours before the procedure, so your stomach is empty. The X -ray test works by positioning the part of the body being X-rayed between the source of the X -ray and an X -ray detector (such as a film).
Barium may cause your stool to turn a whitish color, and iodine injections may cause some people to feel sick or develop a rash. Injections given to relax the stomach before an X -ray of that body part may cause temporary blurred vision.
Although previous studies have suggested such X -ray cartography is possible in principle, this is the first time that any real-world visualization of stiffness using the concept has been demonstrated. How long it takes those protons to make this move tells us a similar story about stiff or hard tissues.
“This greater precision doesn't just mean identification of much smaller or deeper lesions,” said lead researcher Water Fashion, an associate professor from the Institute of Multidisciplinary Research for Advanced Materials (IMAM) of Took University, “but, importantly for patients, because smaller lesions can be newer ones, potentially also much earlier on in a disease or condition.” The next step is to further develop the technique to produce 3-D visualizations, and ultimately the researchers want to manufacture X -ray cartography medical diagnostic equipment.

The amount of radiation you're exposed to during an X -ray depends on the tissue or organ being examined. Generally, however, radiation exposure from an X -ray is low, and the benefits from these tests far outweigh the risks.
In general, you undress whatever part of your body needs examination. You may wear a gown during the exam, depending on which area is being X-rayed.
Contrast mediums, such as barium and iodine, help outline a specific area of your body on the X -ray image. You may swallow the contrast medium or receive it as an injection or an enema.
The machine produces a safe level of radiation that passes through your body and records an image on a specialized plate. A technologist positions your body to obtain the necessary views.
