Radionuclide Diagnostics

Radionuclide scanning

A radionuclide is an unstable isotope that becomes more stable when it releases energy as radiation (nuclear decay). This radiation may include the emission of a particulate or gamma-ray photons.

Radiation diagnostic methods in nephrology

Radiation, or visualization, methods of examination occupy an important place in the diagnostics and differential diagnostics of kidney diseases. Their role has increased especially in recent years due to technical improvements in methods, which has significantly increased their resolution and safety.

Radioisotope diagnostics of urological diseases

Modern medical disciplines are impossible without interaction with related specialties, especially diagnostic ones. Successful treatment and its prognosis largely depend on the quality and accuracy of diagnostic studies.

Angiography of the brain and spinal cord

Angiography is a method of examining the vascular system of the brain and spinal cord by injecting a contrast agent into the arteries supplying blood to the brain. It was first proposed by Monitz in 1927, but its widespread use in clinical practice began only in the 1940s.

Thermography

Medical thermography is a method of recording the natural thermal radiation of the human body in the invisible infrared region of the electromagnetic spectrum. Thermography determines the characteristic "thermal" picture of all areas of the body. In a healthy person, it is relatively constant, but changes in pathological conditions.

Clinical radiometry

Clinical radiometry is the measurement of radioactivity of the whole body or part of it after the introduction of a radiopharmaceutical into the body. Gamma-emitting radionuclides are usually used in clinical practice.

Single-photon emission tomography

Single-photon emission tomography (SPET) is gradually replacing conventional static scintigraphy, as it allows for better spatial resolution with the same amount of the same radiopharmaceutical, i.e. to detect significantly smaller areas of organ damage - hot and cold nodes. Special gamma cameras are used to perform SPET.

Scintigraphy

Scintigraphy is the production of images of a patient's organs and tissues by recording the radiation emitted by an incorporated radionuclide on a gamma camera.

Radionuclide study

The distance between physics laboratories, where scientists recorded the tracks of nuclear particles, and everyday clinical practice seemed depressingly long. The very idea of using nuclear-physical phenomena to examine patients might seem, if not crazy, then fabulous. However, this was the idea that was born in the experiments of the Hungarian scientist D. Hevesi, who later won the Nobel Prize.
