According to a study published in the National Library of Medicine, radiation therapy significantly improves the survival rates and quality of life in cancer patients undergoing treatment.
Utilization of Radioactive Isotopes in Cancer Imaging
One of the key applications of nuclear chemistry in cancer treatment is the use of radioactive isotopes for imaging purposes. This technique, known as nuclear imaging or nuclear medicine imaging, allows healthcare providers to visualize and diagnose various types of cancer in patients.
Radioactive isotopes are used in imaging studies such as positron emission tomography (PET) scans and single-photon emission computed tomography (SPECT) scans. These scans involve the injection of a radioactive tracer, which travels through the body and emits gamma rays. The gamma rays are then detected by special cameras that create detailed images of the internal structures and functions of tissues and organs.
Radioactive isotopes commonly used in cancer imaging include fluorine-18, technetium-99m, and iodine-131. These isotopes have specific properties that allow them to target and accumulate in cancerous cells, making them ideal for detecting tumors and monitoring the progression of the disease.
Benefits of Nuclear Imaging in Cancer Diagnosis:
