Nuclear imaging is an advanced medical diagnostic test which uses radioactive tracer to examine your organs and tissue. It is a good alternative to the traditional imaging methods, such as X-rays.
What is nuclear imaging?
Nuclear medicine imaging is a specialty of radiology that uses very small amounts of radioactive chemicals (radiopharmaceuticals) to study the function of your body. This is typically done to detect any abnormalities in the early stages of a condition.
What are some of the risks?
The main risks of nuclear imaging are allergic reactions and radiation risk. These reactions are extremely rare and patients usually have no issues with the tests.
What are radioactive tracers?
Nuclear medicine makes use of many different types. Some tracers have a very narrow application to a certain type of tissue or an organ. Others work on a more broad basis, such as the ability to track blood flow in the body.
What does the radioactive tracer look like?
Tracers are made up of a series of carrier molecules that are bonded tightly to a radioactive atom. These carrier molecules may be injected in the patient, or they can be placed on an organ that will undergo scanning. Some tracer molecules are special molecules that react with proteins or sugars in the body.
What are the different nuclear medicine imaging techniques?
The two most popular nuclear medicine imaging techniques include single photon emittance computed tomography and positron emissions tomography. These two procedures are performed using radiopharmaceuticals that produce 3-dimensional images of internal organs.
SPECT utilizes gamma rays, which are emitted by radioactive tracers as they pass through the body. Gamma rays can be detected using a gamma scanner that generates digital signals. The signals are used to create 3D imaging of your internal tissues by a computer.
How long does the nuclear scan last?
The time required for a nuclear scan is between 30 and 60 mins, plus any waiting period after receiving radioactive material. You can do the scans in one visit or spread out over a number of days.
What is the most common area of your body to receive a scan?
You will be lying on a table inside a rotating machine during the nuclear scan. A camera inside the SPECT takes images of your internal organs, and other parts. The images are sent to a computer, which uses them to create 3D pictures of your organs.
What are the different types of radioactive tracers that can used in nuclear imaging?
Doctors may use different radioactive tracer depending on the part of your body that is being scanned. These include elements like technetium.
What do radioactive traces appear like?
Most of the radioactive trace used in nuclear imaging is made of very specific molecule. These molecules may be a combination between a carrier that is tightly bound to a radioactive nuclear tracer and a molecule composed of an atom special that interacts a sugar or protein inside your body.
FAQ
What is the difference between a doctor and a physician?
A doctor refers to a person who is licensed to practise medicine and has completed his/her training. A physician is a doctor who specializes in a particular area of medicine.
What is an infectious disease?
Infectious disease can be caused by germs (bacteria or viruses) Infectious disease spreads quickly when people come in close proximity. Examples include measles, mumps, pertussis (whooping cough), rubella (German measles), chickenpox, strep throat, tuberculosis, influenza, polio, hepatitis A and B, HIV/AIDS, herpes simplex virus, syphilis, gonorrhea, and chlamydia.
What role can I play in public healthcare?
Participating in preventive efforts can help to protect your own health and that of others. You can also contribute to improving public health by reporting any injuries or illnesses to healthcare professionals to help them prevent future ones.
What is the best way to learn about health insurance?
You should always keep track of the policy documents if you have insurance for health. Ask questions if you are unsure about your plan. Ask your provider questions or call customer support if you don't get it.
When it comes to using your insurance, make sure you take advantage of the deductible. Your deductible is the amount you must pay before your insurance begins covering the rest of your bill.
What are the best ways to get free insurance for my health?
If you meet the eligibility requirements, you may be eligible for free insurance. You might be eligible for Medicaid, Medicare, CHIP, Children's Health Insurance Program (CHIP), Tricare, VA benefits, Federal Employee Health Benefits (FEHB), military health plans, Indian Health Service (IHS) benefits, or some other program.
What does it mean to "health promote"?
Health promotion refers to helping people stay healthy and live longer. It focuses more on preventing disease than treating it.
It includes activities like:
-
Eating right
-
Get enough sleep
-
exercising regularly
-
Staying active is key to staying fit
-
Smoking is not permitted
-
managing stress
-
Keeping up with vaccinations
-
How to avoid alcohol abuse
-
having regular checkups and screenings
-
How to manage chronic illness.
What does "health care" actually mean?
Providers of health care are those who provide services to maintain good mental and physical health.

Americans spend 9% on average for their health expenses.
-
As of 2014 there were more than 300,000,000 Americans who weren't insured.
-
Although the Affordable Health Care Act (ACA), has been approved by Congress, it hasn't yet been fully implemented. There are still significant gaps in coverage.
-
A majority of Americans believe that there should be continued improvement to the ACA.
-
The US spends the most money on healthcare in the world than any other country.
