Radioisotopes are used in nuclear medicine primarily for imaging internal organs and tissues, allowing for the diagnosis and monitoring of various medical conditions.

Iodine-131 is commonly used in nuclear medicine imaging, particularly for thyroid function tests and treatment of thyroid disorders.

Radioisotope administration refers to the process of introducing a radioisotope into a patient's body, typically through injection or ingestion, for diagnostic or therapeutic purposes.

SPECT is a nuclear medicine imaging technique that uses gamma rays emitted by radioisotopes to create three-dimensional images of internal organs and tissues.

Radiation therapy primarily works by damaging the DNA of cancer cells, leading to their death or inhibition of their growth.

Gamma rays are commonly used in radiation therapy for cancer treatment due to their high energy and ability to penetrate deep into tissues, targeting cancer cells.

Radioisotope therapy refers to the use of radioisotopes to treat diseases, typically by targeting specific cells or tissues with the radiation emitted by the radioisotope.

Iodine-131 is commonly used in radioisotope therapy, particularly for the treatment of thyroid cancer and hyperthyroidism.

Radioisotopes allow for the tracking of metabolic processes within the body, providing valuable information for diagnosing and monitoring various medical conditions.

Radioisotopes are also used in the sterilization of medical devices and equipment through a process called gamma irradiation.

Radiobiology is the field of study that focuses on the effects of radiation on biological systems, including the interactions between radiation and living organisms.

Technetium-99m is commonly used in nuclear medicine for bone scans due to its ability to accumulate in bone tissue, allowing for the detection of bone abnormalities.

Radiolabeling involves attaching radioisotopes to molecules of interest, allowing for their detection and tracking within biological systems.

Iodine-131 is commonly used in the treatment of thyroid cancer due to its ability to accumulate in thyroid tissue, delivering targeted radiation to cancer cells.

Molecular imaging utilizes radioisotopes to label and track biological molecules, allowing for the study of their structure, function, and interactions within living organisms.
