Nuclear Medicine Technology


Nuclear medicine technology is one kind of special medical treatment with the use of Safe and little amount of radioactive material for diagnostic, therapeutic, and research purposes. Nuclear medicine technology uses radioactive materials to perform body function studies.

The nuclear medicine technology also uses for organ imaging, analyze biologic specimens and treat, manage, and prevent serious disease. Sometimes nuclear medicine technology can result in more effective treatment and better prognosis for comprehensive diseases. Scientists now give proper treatment for critical diseases by using this technology.


This technology combined the use of radioactive substances, detectors, and computers to provide physicians to see the human body. Positron emission tomography (PET) and single-photon emission computed tomography (SPECT) are included in these specific techniques. The nuclear medicine imaging is applied to detect tumors, irregular or inadequate blood flow to various tissues, blood cell disorder, and inadequate functions of organs.In the time of diagnostic, the patient may experience little of o discomfort. The radiation of the nuclear technique is small.

This type’s technologists are highly skilled. They have to be highly skilled because they work closely with nuclear medicine physicians. They have some responsibilities that are Vivo procedures, performing radiation safety, and quality control procedures. Operating the cameras that create an image and patient positioning and education are also included as their responsibility. The skilled technologists collect paper and analyze biologist specimens. Then they prepare data for the physicians.

Radioactive materials are used to diagnose and for the treatment of difficult diseases in nuclear medicine. Radiopharmaceuticals attracted specific organs, bones, or tissues. Emit gamma rays that can be detected externally by scintillation cameras. And then all images and pictures are created by computers and give data and information. The total amount of radiation is comparable to that receive during a diagnostic x-ray.

Before the procedure, the technologist explains the test report to the patient. Then he prepares a dosage of the radiopharmaceutical. While preparing technologists to adhere to safety standards that keep the radiation dose as low as possible. After positioning the image, the technologist starts a gamma scintillation camera. This camera scans the radioactive material and creates images of its distribution and emits signals from the patient’s body.

The technologist also has to perform radioimmunoassay studies. The studies assess the behavior of a radioactive substance in the body.

Nuclear medicine technologists work in a variety of clinical settings. Their workplace may including community hospitals, university-affiliated teaching hospitals, research institutions, imaging centers, public health institutions, and physicians’ offices. Some technologists work as sales or training representatives for medical equipment and radiopharmaceutical manufacturing firms. Some work as radiation safety officers in regulatory agencies or hospitals. Radiation risks do exist in the workplace. But the risk kept to a minimum by adherence to strict safety guidelines include the use of shielded syringes, gloves, and another protective device. Technologists wear badges to measure radiation levels.

Education and training

To build a Nuclear medicine technology carrier it needs a strong background in anatomy, physiology, mathematics, chemistry, physics, radiation safety, clinical nuclear instrumentation, and laboratory technique.

Nuclear medicine technology programs take one to four years according to various programs. One can earn a certificate, bachelor’s degree. Radiologic technologists take a year certificate program to specialize in nuclear medicine. Like a bachelor program, hospital and community college offered certificate programs for four years.

There two national certification exams are held one is the American registry of radiologic technologists and the Nuclear medicine technologist certification board.
