Nuclear imaging is an advanced medical diagnostic test which uses radioactive tracer to examine your organs and tissue. It's an alternative to other imaging methods such as X rays and CT scanners.
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 done in order to detect abnormalities at an early stage of disease.
What are some of the risks?
Radiation and allergic reactions are the main risks associated with nuclear imaging. These risks are extremely rare, and many patients do not experience any adverse reactions to these tests.
What is the radioactive tracer?
There are many different types of tracers that are used in nuclear medicine. 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 is the appearance of these radioactive tracers like?
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 tracer molecules are special molecules that react with proteins or sugars in the body.
What are the different nuclear medicine imaging techniques?
Single photon emission computed Tomography (SPECT), and positron-emission tomography, are the two most commonly used nuclear medicine imaging methods. These two procedures employ radiopharmaceuticals for the production of three-dimensional pictures of the internal organs.
SPECT is performed using gamma beams emitted by radioactive tracer particles as they move through the body. Gamma cameras produce digital signals from the gamma-rays. These signals are used by the computer to create 3D views of your internal organs.
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 are the most commonly scanned areas on your body?
During the nuclear scan, you will lie on a table in a machine that rotates around you. A camera on the SPECT captures images of your organs and body parts. These images are then sent into a computer which creates 3D images of the organs in your body.
What type of radioactive tracers can you use for nuclear imaging?
Depending on which part of your body is being examined, doctors can choose from a range of radioactive markers. These include forms of the elements technetium, thallium, gallium, iodine and xenon.
What are these radioactive traces?
The majority of radioactive traces that are used in nuclear medicine imaging consist of very specific molecules. 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 are the main functions of a health care system?
The health system must provide quality medical services at affordable prices to all people.
This includes providing preventive healthcare, promoting healthy lifestyles, as well as appropriate treatment. It also includes equitable distributions of health resources.
What are the different types and benefits of health insurance
There are three main types for health insurance:
-
Private health insurance covers most of the costs associated with your medical treatment. This type of insurance is often purchased directly from private companies, so you pay monthly premiums.
-
While public insurance covers the majority cost of medical care there are restrictions and limitations. Public insurance, for example, will not cover routine visits to doctors or hospitals, labs and X-ray facilities.
-
For future medical expenses, medical savings accounts are used. The funds are held in a special account that is separate from any other kind of account. Many employers offer MSA programs. These accounts do not have to be taxed and can earn interest at the same rate as bank savings.
What is the difference between the health system and health care services?
Health systems can be more than just providing healthcare services. They encompass everything that happens in the overall context of people’s lives, such as education, employment, housing, and social security.
Healthcare services, on other hand, provide medical treatment for certain conditions like diabetes, cancer and mental illness.
They could also refer to generalist primary care services provided by community-based physicians working under the supervision of an NHS trust.
Why do we need medical systems at all?
Many people living in poor countries lack basic healthcare facilities. Many people living in these areas will die before they reach their middle years from diseases such as tuberculosis.
The vast majority of people in developed nations have regular checkups. Minor illnesses are usually treated by their general practitioner. However, many people continue to suffer from chronic conditions like diabetes and heart disease.
Statistics
- About 14 percent of Americans have chronic kidney disease. (rasmussen.edu)
- The health share of the Gross domestic product (GDP) is expected to continue its upward trend, reaching 19.9 percent of GDP by 2025. (en.wikipedia.org)
- Over the first twenty-five years of this transformation, government contributions to healthcare expenditures have dropped from 36% to 15%, with the burden of managing this decrease falling largely on patients. (en.wikipedia.org)
- Price Increases, Aging Push Sector To 20 Percent Of Economy". (en.wikipedia.org)
- For instance, Chinese hospital charges tend toward 50% for drugs, another major percentage for equipment, and a small percentage for healthcare professional fees. (en.wikipedia.org)

What are the Key Segments of the Healthcare Industry?
The key segments of healthcare include pharmaceuticals, diagnostics biotechnology, therapeutics, diagnosis, biotechnology and medical equipment.
Medical devices include blood pressure monitors, defibrillators, stethoscopes, ultrasound machines, etc. These devices are designed to diagnose or prevent disease.
Pharmaceuticals are drugs that are prescribed to treat disease or reduce symptoms. Some examples include antihistamines and antibiotics.
Diagnostics are tests performed by laboratories to detect illness or injury. Examples include blood tests, urine samples, CT scans, MRI scans, X-rays, etc.
Biotechnology refers the process of creating useful substances from living organisms such as bacteria. These include insulin, vaccines and enzymes.
Therapeutics refer to treatments given to patients to alleviate or treat symptoms. These therapies can include drugs or radiation therapy.
Health information technology includes computer software programs that help physicians, and their teams manage data related to patient records. It helps doctors and their teams track which medications are being used, when they should have been taken, and if they work properly.
Medical equipment is anything used to diagnose, treat, or monitor conditions or illnesses. Dialysis machines, pacemakers and ventilators are just a few examples.
