Medical treatments using Nuclear power

there are many types of medical treatments that use nuclear energy. five different types to be exact. including MRI, X-ray, PET, Radiation counselling, and Radiotracers

Medical Treatments for Nuclear Radiation

  • Nuclear Radiation can be treated with Nuclear medicine. This medicine uses radiation to provide information
about the functioning of a person's specific organs or to treat disease.
  • Also another treatment is called radiotherapy. That can be used to cure diseases such as cancer and is used to destroy the targeting cells.
  • When using nuclear radiation medicine is very safe and also causes no pain.


MRI Scans


MRI (Magnetic resonance imaging) is a medical imaging procedure that uses magnetic fields and radio waves to produce cross sectional images of the internals of the human body. The way MRI's work is that they detect the amounts of water content, being able to find different tissues in and on the human body. A MRI shows a lot more than the traditional x-ray can. It can show both bones, and the organs and tissues in detail. The way that the MRI works is the patient is surrounded by a electric current in the machine. Radio waves are then transmitted through the machine and person, creating a digital image seen on monitors.

Uses of MRI scans are:
Abnormalities of the brain and spinal cord
Tumors, cysts, and other abnormalities in various parts of the body
Injuries or abnormalities of the joints
Certain types of heart problems
Diseases of the liver and other abdominal organs
Causes of pelvic pain in women (e.g. fibroids, endometriosis)
Suspected uterine abnormalities in women undergoing evaluation for infertility

Risks of MRIs:
-The magnet may cause pacemakers, artificial limbs, and other implanted medical devices that contain metal to
malfunction or heat up during the exam.
-Any loose metal object may cause damage or injury if it gets pulled toward the magnet.If a contrast agent is used, there is a slight risk of an allergic reaction. MRI contrast agents can cause problems in patients with significant kidney disease.
Dyes from tattoos or tattooed eyeliner can cause skin or eye irritation. Medication patches can cause a skin burn.
The wire leads used to monitor an electrocardiogram (ECG) trace or respiration during a scan must be placed
carefully to avoid causing a skin burn. Prolonged exposure to radio waves during the scan could lead to slight warming of the body.

PET Scans


PET scans or positron emission tomography is an imaging test that uses a radioactive substance called a tracer to look for disease in the body. These tests are used to see tissues on the body. This scan works by injecting through an IV radiation. The radiation takes some time to be mixed with the blood. Once mixed you go onto the same bed or table as an MRI scan. The radiation is seen with cameras that print photos onto a monitor. These tests are used for the same reasons as MRI scans. They look for abnormalities in the body like cancers, diseases, and other illnesses.

The risks of a PET scan are very limited. The radiation dosage is not damaging to adults, but parents who breast feed or are pregnant may want to opt out of the test.

X-Rays



An x-ray is a test using radiation to see the inside of a human body, usually bones. The muscle and fats of the body are barely seen along with other organs. X-rays are used for all parts of the body, like head, chest, and legs. They are used to find diseases, cancers, and other illnesses. The risks of getting an x-ray are the same as PET and MRI scans. The major risks are towards pregnant women or women who breast feed.

Radiotracers


Radiotracers are a sub category to PET scans. They are injected into the blood stream through an IV. They are again, used to find illnesses and abnormalities in the body. Cameras pick up the radiation and the area they are in to get detailed images of the tissues of someone's body.
