Nuclear imaging, also known as medical diagnostic testing, uses radioactive tracers in order to study the organs and tissues of your body. It's an alternative to other imaging methods such as X rays and CT scanners.
What is nuclear Medicine 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 often done to detect anomalies very early in a disease's course.
What are the possible risks?
The two biggest risks from nuclear imaging are radiation and allergic reactions. These risks are extremely rare, and many patients do not experience any adverse reactions to these tests.
What is the radioactive tracer?
Nuclear medicine uses many types of tracers. Some tracers work only on a specific type of organ or tissue. Others work on a more broad basis, such as the ability to track blood flow in the body.
What does it look like when you use radioactive tracer?
Tracers contain a series of carrier molecule tightly bound with a radioactive particle. These molecules are usually placed either on the internal organs to be scanned or injected into a patient. Some tracers consist of a molecule which interacts with sugar or protein in the human body.
What are the different nuclear medical imaging techniques?
The most common nuclear imaging techniques are single-photon emission computedtomography (SPECT), as well as positron emission Tomography (PET). The two procedures produce images in three dimensions of the organs using radiopharmaceuticals.
The SPECT uses gamma-rays that are emitted as radioactive tracer passes through the body. Gamma rays can be detected using a gamma scanner that generates digital signals. These signals are used by the computer to create 3D views of your internal organs.
How long does a nuclear scan take?
A nuclear scan will take 30-60 minutes plus time for waiting after radioactive materials are given. The scans can be performed in a single session or over several days.
What are the most commonly scanned areas on your body?
During the nuclear scanning, you will lie down on a circular table. A camera in the SPECT machine captures pictures of your internal organs and other parts of your body. These images are sent by computer to create 3D models of organs and body parts.
What type of radioactive tracers can you use for nuclear imaging?
Doctors can use a variety of radioactive tracer substances, depending on what part of the body is being scanned. These include various forms of the element technetium.
What do these radioactive traces look like?
Most of the radioactive trace used in nuclear imaging is made of very specific molecule. These molecules are a combination of either a carrier molecule tightly bonded to a radioactive tracer, or a molecule made of a special element that interacts with sugar or protein in your body.
FAQ
What does "public" mean in public health?
Public Health refers to the preservation and enhancement of the health status of the community. It involves preventing disease, injury, and disability, promoting good health practices; ensuring adequate nutrition; and controlling communicable diseases, environmental hazards, and behavioral risks.
What are the main types of health insurance?
There are three types of insurance that cover health:
-
Private insurance covers the majority of your medical costs. This type of insurance is often purchased directly from private companies, so you pay monthly premiums.
-
Public health insurance covers most of the cost of medical care, but there are limits and restrictions on coverage. Public insurance doesn't cover everything.
-
Medical savings accounts (MSA) are used to save money for future medical expenses. The funds are kept in a separate account. Many employers offer MSA programs. These accounts are exempt from tax and earn interest at rates comparable to savings accounts.
What is a health care system?
All aspects of healthcare, from prevention to rehabilitation, are covered by health systems. It includes hospitals as well as clinics, pharmacies, community health services, long-term and home care, addictions, palliative care, regulation, finance, education, and financing.
Health systems are complex adaptive systems. They have emergent properties which cannot always be predicted by looking at individual components.
It is difficult to manage and understand complex health systems because of their complexity. This is where creativity steps in.
Creativity allows us to find solutions for problems we don’t know how. Our imaginations are used to invent new ideas and improve things.
Because they are constantly evolving, health systems require people who think creatively.
Individuals who think creatively have the potential to change the way healthcare systems operate.
What does "health promotion” actually mean?
Promoting health is about helping people live longer and stay healthy. It focuses more on preventing disease than treating it.
It also includes:
-
Healthy eating
-
Get enough sleep
-
exercising regularly
-
Staying active is key to staying fit
-
Not to smoke
-
managing stress
-
Keeping up to date with vaccinations
-
Avoid alcohol abuse
-
Regular checkups and screenings
-
Understanding how to cope with chronic diseases.
How can I get my free health insurance?
If you meet the eligibility requirements, you may be eligible for free insurance. You might be eligible if you qualify for Medicaid, Medicare and CHIP.

How To
How to Find Home Care Facilities
People who need assistance at home are assisted by home care facilities. Home care facilities can be used by elderly or disabled individuals who are unable to get around on their own, as well those suffering from chronic diseases like Alzheimer's. These facilities offer services such as personal hygiene, meal preparation and laundry, cleaning, medication reminders, transportation, and so on. They often work with rehabilitation specialists, social workers and medical professionals.
Recommendations from family, friends, and local businesses or reviews online are the best ways to find a home-care service provider. Once you have found a couple of providers, it is time to get in touch with them to learn more about their qualifications. Look for providers that offer flexible hours to accommodate your needs. Also, make sure they offer emergency assistance 24/7.
Ask your doctor or nurse to refer you. If you don't know how to search, try searching online for "home healthcare" or "nursing home". You could, for example, use websites such Angie's List HealthGrades or Yelp.
For more information, you can also contact your local Area Agency on Aging or Visiting Nurse Service Association for further assistance. These organizations will be able to provide you with a list containing agencies in your local area that are specialized in home care services.
Finding a good home care agency is important because many companies charge high patient fees. In fact, some agencies can charge up to 100% of an individual's monthly income. Avoid this problem by selecting an agency that has been highly reviewed by the Better Business Bureau. Get references from former clients.
Some states even require home care agencies to register with the State Department of Social Services. To find out what registration requirements your agency must meet, check with your local government office.
There are several things to keep in mind when choosing a home care agency :
-
Do not pay upfront for any services if you are being asked.
-
Choose a well-established, reputable company.
-
For those who are paying out-of-pocket for insurance, make sure you have proof.
