What is General Nuclear Medicine?
In traditional diagnostic imaging, an external energy source such as X-rays, magnetic fields, or ultrasound waves is used to produce images of bone and soft tissue. Nuclear medicine imaging procedures use a specially designed agent that is associated with a very small amount of radioactive material. These substances, called radiopharmaceuticals, isotopes or markers, are absorbed into certain organs, bones or tissues….

In nuclear medicine, the source of energy is the radioactive material that enters the body. For nuclear medicine research, a small amount of a radioisotope is administered orally or by injection to a patient to improve visualization of selected organs or vascular structures. Once the radioisotope has accumulated in the area of the body being examined, the technologist places a camera near that area and begins the scanning process. The images are viewed on a computer monitor after being examined by a specially trained doctor who will report the results to your doctor…
Today, technetium-99m is the most widely used element in nuclear medicine and is used in a wide variety of nuclear medicine image research. This practice is often referred to as image fusion or co-recording, such as SPECT / CT and PET / CT. Nuclear medicine fusion imaging technology provides information about anatomy and function that would otherwise be unavailable or require a more invasive procedure or operation..
For this reason, it is called physiological imaging modality. Single-photon computed tomography and positron emission tomography are two of the most common imaging techniques in nuclear medicine. The FDA and states regulate the use of radioactive materials in nuclear medicine to ensure the safety of patients, medical personnel, and the public. Before using any type of nuclear medicine procedure, it is necessary to justify it so that the benefits of the procedures outweigh the risks to the patient. but, https://www.nirs.org/press/09-15-2009/ Exposure to too much radiation can quickly damage organs or tissues, while exposure to any amount of radiation can increase the risk of cancer years after exposure. Image The soft exterior icon is a campaign that encourages healthcare providers to use quantities of “baby-sized” radioactive material when a child is undergoing nuclear medicine. In traditional diagnostic imaging, an external energy source such as X-rays, magnetic fields, or ultrasound waves is used to obtain body anatomy images…
brought further development in the field of describing the successful treatment of a patient with metastatic thyroid cancer with radioactive iodine (I-131). Many historians consider these to be the most important articles ever published in the field of nuclear medicine. Among the many radionuclides that have been discovered for medical use, none has been as important as the discovery and development of the 99m technetium. Segre as an artificial element to fill the 43rd place in the Periodic Table. The development of a generator system for the production of technetium-99m in the 1960s became a practical method for medical use..
The purpose of this diagnostic test is to provide an image that assesses organ function and localizes a disease or tumor. A nuclear scan also shows the size, shape and position of the organ being scanned. After being given a small dose of radioactive material, images can be captured using a special camera based on the energy produced by the radioactive material. The degree to which an indicator is absorbed by a particular organ or tissue may indicate the level of functioning of this system. A diseased or malfunctioning organ emits a different signal from a healthy organ. One of the unique features of a nuclear medicine scan is that it shows the “function” of the organ or tissue being evaluated, rather than just an image. Nuclear medicine is a medical specialty in which radioactive tracers are used to help diagnose and treat a wide range of diseases….

As an integral part of patient care, nuclear medicine is used to diagnose, manage, treat and prevent serious diseases. Nuclear medicine imaging procedures often reveal abnormalities very early in disease progression, long before some medical problems become apparent with other diagnostic tests. This early detection allows the disease to be treated at an early stage when there can be a better prognosis. Nuclear medicine is a medical specialty that uses radioactive substances to diagnose and treat disease. In addition, nuclear medicine scans differ from radiographic scans because the emphasis is not on the anatomy of the image but on the function.
Once the indicator is inserted, the gamma camera and computer are used to create images or scan important functions of the body and organs. Scans are usually performed in conjunction with other imaging studies that provide more anatomical information on areas of interest. Nuclear medicine is a safe, painless, and cost-effective way to gather information that might otherwise be unavailable or that requires more expensive and risky diagnostic tests. One of the unique aspects of a nuclear medicine test is its extreme sensitivity to abnormalities in the structure or function of organs….
