Use Of Radioactive Materials In Nuclear Medicine

Medicine that uses radioactive materials is called nuclear medicine, which is also known is referred to as nuclear medicine. Which radioactive materials are used in some studies and in the provision of treatment of some diseases?

Everywhere natural radioactivity

Everywhere around us is invisible, odorless, tasteless and intangible radioactivity. Which radioactivity is slightly more present under the soil, air, walls, our food and our body tissues? These quantities are called natural radioactivity and are not harmful. Also, the radiation in the conduct of studies with the use of radioactive material is very low, but in the treatment of disorders the radiation is higher.

Radioactive substance administered in research

In investigations carried out in the nuclear medicine a patient is given a small amount of radioactive substance is administered after which the functioning of the body and organs can be examined. The kind of substance to be administered is dependent on the research that is being done. There are different ways to administer the choice being determined by the type of study. The substance the most commonly used way is to inject into the bloodstream. The substance an important feature of radioactive material is that it emits radiation that can be easy. Collected!

Radiation provides information for determining diagnosis

After administration, the substance is taken up by parts of the body or bodies to be examined. Then the radiation emitted from the body parts or organs recorded by a special camera creates an image scan is called. That image provides information about the body and the functioning of certain organs after which a diagnosis can be made.

Preparation for examination

The preparation of such an examination may be different depending on the type of research. Sometimes it is not allowed to eat or advance should be taking drugs to stop put. For research from a certain moment the time an investigation takes is varying.

Care in nuclear medicine

Although radiation in principle is detrimental to the human body is there with this kind of research because less of the amount of radiation is very low and hardly causes harm to healthy tissue. Still going nuclear medicine extreme care and only go on to study after they are convinced that the research has real utility for the patient.

Higher dose radioactive substance

It is certain that even the case where radioactive substance is used in the treatment of disorders. The applied dose of radioactive material is much higher than that is used. At the investigations for treatments is so much dust that it is used diseased tissue is rendered harmless but which is restricted. The damage to the healthy cells as much as possible the treatment in this way be applied to both benign and malignant diseases. Typically those treatments are outpatient, but sometimes a recording in an isolated room necessary because the radiation is too high. Once these back under the legal standard, the patient can leave the hospital.

Example of nuclear research

An example of a nuclear research is investigating a possible shortage of oxygen in the heart muscle, which may be a narrowing in the coronary arteries caused. Because the research is also clear how extensive this potential shortage of oxygen. This study looks at the blood flow in the heart muscle. The research is conducted by making a vasodilator spray through an IV in the arm and administer. radioactive material after a maximum impact An alternative is to by means of a cycling test to come to the vasodilating effect, and then to administer.
