I am About 23 years ago I was diagnosed with hypothyroidism. So I have struggled with thyroid medication to keep me going. What I do now is make sure I have a radiation apron on my neck when ever I get an xray or mamogram etc. Suggest everyone who gets a mamogram has a cover for the thyroid. Once you lose the thyroid you are subjected to life long dependency on the pharmaceutical industry creating a pill that keeps you alive.
And the costs are rising. Oddly enough the insurance companies do not cover the best thyroid medication. Armour Thyroid. Deb W RN. Would Neuroendicrine cancer patients be at risk for developing other types of cancer cells due to receiving CT scans every months on a yearly basis? An X-ray is a quick, painless test that produces images of the structures inside your body — particularly your bones.
X-ray beams pass through your body, and they are absorbed in different amounts depending on the density of the material they pass through. Dense materials, such as bone and metal, show up as white on X-rays. The air in your lungs shows up as black. Fat and muscle appear as shades of gray. For some types of X-ray tests, a contrast medium — such as iodine or barium — is introduced into your body to provide greater detail on the images.
Knee arthritis can affect one side of the joint more than the other. This X-ray image shows how the cushioning cartilage has worn away, allowing bone to touch bone. A chest X-ray helps detect problems with your heart and lungs. The chest X-ray on the left is normal. The image on the right shows a mass in the right lung. Some people worry that X-rays aren't safe because radiation exposure can cause cell mutations that may lead to cancer.
The amount of radiation you're exposed to during an X-ray depends on the tissue or organ being examined. Sensitivity to the radiation depends on your age, with children being more sensitive than adults.
Generally, however, radiation exposure from an X-ray is low, and the benefits from these tests far outweigh the risks. However, if you are pregnant or suspect that you may be pregnant, tell your doctor before having an X-ray. Though the risk of most diagnostic X-rays to an unborn baby is small, your doctor may consider another imaging test, such as ultrasound.
This X-ray using contrast reveals a kidney stone at the junction of the kidney and the tube that connects the kidney to the bladder ureter.
The X-ray tube is focused on the abdomen. X-rays will pass through the body and produce an image on the specialized plate below. For more information, see GOV. UK: patient dose information. The benefits and risks of having an X-ray will be weighed up before it's recommended. Talk to your doctor or radiographer about the potential risks beforehand, if you have any concerns. Page last reviewed: 13 July Next review due: 13 July How X-rays work X-rays are a type of radiation that can pass through the body.
When X-rays are used X-rays can be used to examine most areas of the body. Problems that may be detected during an X-ray include: bone fractures and breaks tooth problems, such as loose teeth and dental abscesses scoliosis abnormal curvature of the spine non-cancerous and cancerous bone tumours lung problems, such as pneumonia and lung cancer dysphagia swallowing problems heart problems, such as heart failure breast cancer X-rays can also be used to guide doctors or surgeons during certain procedures.
Preparing for an X-ray You don't usually need to do anything special to prepare for an X-ray. Having an X-ray During an X-ray, you'll usually be asked to lie on a table or stand against a flat surface so that the part of your body being examined can be positioned in the right place.
More than one X-ray may be taken from different angles to provide as much information as possible The procedure will usually only take a few minutes. Contrast X-rays In some cases, a substance called a contrast agent may be given before an X-ray is carried out. Types of X-rays involving a contrast agent include: barium swallow — a substance called barium is swallowed to help highlight the upper digestive system barium enema — barium is passed into your bowel through your bottom angiography — iodine is injected into a blood vessel to highlight the heart and blood vessels intravenous urogram IVU — iodine is injected into a blood vessel to highlight the kidneys and bladder These types of X-rays may need special preparation beforehand and will usually take longer to carry out.
What happens after an X-ray You won't experience any after effects from a standard X-ray and will be able to go home shortly afterwards. Additionally, the Earth is constantly bombarded by cosmic radiation, which includes X-rays. These rays are not harmless but they are unavoidable, and the radiation is at such low levels that its effects are virtually unnoticed. Pilots, cabin crew, and astronauts are at more risk of higher doses because of the increased exposure to cosmic rays at altitude.
There have, however, been few studies linking an airborne occupation to increased incidence of cancer. To produce a standard X-ray image, the patient or part of their body is placed in front of an X-ray detector and illuminated by short X-ray pulses.
Because bones are rich in calcium , which has a high atomic number, the X-rays are absorbed and appear white on the resulting image. Any trapped gases, for instance, in the lungs, show up as dark patches because of their particularly low absorption rates. Radiography: This is the most familiar type of X-ray imaging. It is used to image broken bones, teeth, and the chest. Radiography also uses the smallest amounts of radiation.
Fluoroscopy: The radiologist, or radiographer, can watch the X-ray of the patient moving in real-time and take snapshots. This type of X-ray might be used to watch the activity of the gut after a barium meal. Fluoroscopy uses more X-ray radiation than a standard X-ray, but the amounts are still extremely small. Computed tomography CT : The patient lies on a table and enters a ring-shaped scanner. A fan-shaped beam of X-rays passes through the patient onto a number of detectors.
This procedure uses the highest dose of X-rays because a large number of images are taken in one sitting. X-rays can cause mutations in our DNA and, therefore, might lead to cancer later in life. However, the benefits of X-ray technology far outweigh the potential negative consequences of using them.
It is estimated that 0. Some scientists expect this level to rise in parallel with the increased use of CT scans in medical procedures.
