PET/CT is a method that simultaneously provides clear anatomical structure images of CT and early lesion images at the cellular and molecular levels of PET, so PET/CT has high sensitivity, specificity, and accuracy, and is capable of detecting lesions and pathologies at very early stages even when they have not been detected on CT, MRI...

Radiation therapy is a method of using high-energy particles or waves (X-rays, gamma rays, etc.) to irradiate cancerous tumors to destroy them. In addition to its main effect of treating cancer, radiation therapy has many side effects.

Radiation sickness, also known as acute radiation syndrome or radiation poisoning, is damage to the body caused by receiving a large amount of radioactive material in a short period of time (acute). The amount of radiation absorbed by the body will determine the level of damage to the body.

Nowadays, the application of nuclear medicine in the diagnosis and treatment of diseases, especially cancer, is becoming more and more popular. The outstanding advantages of this method are accuracy, safety and high treatment efficiency for patients.

Renal function scintigraphy is a simple, easy-to-perform diagnostic technique that is very valuable in kidney diseases. Renal scintigraphy not only provides information on the function of each kidney through quantitative and qualitative analysis, but also provides information on the location, size and anatomy of the kidney. In addition, this test is very useful in cases where patients are sensitive to contrast agents containing high levels of iodine or urea and cannot undergo X-rays.

Ionizing radiation originates from external sources such as gamma rays, X-rays or from radioactive isotopes introduced into the body for the purpose of treating diseases. Radiation exposure occurs when the concentration of ionizing radiation entering the body exceeds the safe level, causing serious health effects and leading to other dangerous diseases.
