Radiology Medical (Nuclear Medicine)

Medical radiology (Nuclear Medicine) is a branch of medicine that uses radionuclides in the process of studying, diagnosing and treating various diseases. In radiology, radiopharmaceuticals are used - substances containing radioactive isotopes. When introduced into the body, they concentrate in certain organs and tissues, emitting gamma quanta, which are recorded by special detectors. This allows you to obtain an image of the organ under study and assess its functional state.

Also in radiology, the therapeutic effect of ionizing radiation from injected radionuclides on the pathological focus is used (radionuclide therapy).

One of the branches of radiology is nuclear cardiology, in which radionuclide methods are used to diagnose heart diseases.

Medical radiology (Nuclear Medicine), also known as nuclear medicine, is a branch of medicine that uses radiation and radioactive nuclides to study, diagnose and treat various diseases. In this field of medicine, certain isotopes and elements are used for diagnosis. These substances have unique properties such as fast half-life, high tissue penetration, and the ability to accumulate in tissues during disease or injury.

Medical radiology uses technologies such as radiography, gamma camera, positron emission tomography (PET), single photon emission tomography

Introduction to medical radiology (nuclear medicine) Medical radiology (nuclear medicine) is a subsection of medicine that uses radionuclide sources to study, diagnose, and treat various pathologies in the patient’s body. Radionuclide diagnostics and treatment have high sensitivity and specificity, so they are often used for the primary diagnosis of malignant and benign neoplasms. The radiologist also has the ability to provide targeted drug treatment for breast, prostate, lung and other organ cancers. Treatment with radioactive gold improves metabolic processes in the brain in Parkinson's disease. Treatment with strontium-89 is used for metastatic bone lesions. Modern and informative radionuclide testing can be used to plan clinical trials and also help in the development of new effective therapies.

Advantages of using radionucloids One of the main advantages of using radiologists is the high quality of visualization of disease areas that may not be visible by other methods. Imaging is carried out using gamma rays or x-rays. The intensity of the glow depends on the amount and location of radioactive isotopes used in the diagnosis. Also, visual observation of the patient can be carried out by one doctor in just a few minutes. Images can be recorded and saved on a CD. Snapshots of images can be recorded in digital format, allowing them to be stored, archived and replayed. As a disadvantage of the method, some risks can be noted not only for the patient, but also for the researcher, especially in cases where it is planned to do a biopsy using a gamma camera. After a nuclear medicine test, the patient needs a change of clothing. This requirement is due to the fact that radioactive particles can settle on the patient’s clothes and skin. It must be kept in mind that

Medical radiology (Nuclear Medicine), also known as nuclear medicine, is one of the branches of medicine that uses radionuclide research to study, diagnose and treat various diseases. This is a very specific branch of medicine, which requires high qualifications from specialists working in this field.

Radionuclides are radioactive isotopes that are used in medicine to visualize various organs and tissues. During the research process, the patient receives a dose of a radioactive isotope, which then accumulates in certain tissues and organs. After this, the patient undergoes an examination, which allows doctors to obtain information about the condition of his body.

One of the most common methods of medical radiology is positron emission tomography (PET). This method is used to evaluate the condition of the brain, heart, lungs, liver and other organs. PET scans provide doctors with information about cell metabolism, allowing them to diagnose various diseases such as cancer, stroke, Alzheimer's disease and others.

Another medical radiology technique that is widely used is single photon emission computed tomography (SPECT). SPECT allows doctors to obtain images of organs and tissues using gamma radiation from radioactive isotopes. This method is also used to diagnose and treat cancer, stroke, Parkinson's disease and other diseases.

In general, medical radiology is a very important branch of medicine, which allows doctors to obtain more accurate information about the patient’s condition and prescribe more effective treatment. However, it also has some limitations and risks, so doctors must be very careful when using radionuclides.
