The medical applications of krypton also stand out. The isotope krypton-85 is used to study blood flow and in nuclear medicine to study lung function for problems. Magnetic resonance imaging (MRI) makes use of isotope krypton-83.
Hyper-polarised MRI scanners based on another isotope of Krypton, 83-Kr, are used across the globe for the study of the spatial distribution of tobacco smoke condensate in the human lungs, which can cause major pulmonary diseases in humans such as lung cancer.
The use of nuclear chemistry in medical technologies is increasing over time. The medical uses can be divided into two categories : medical imaging of organs or diagnosing any malfunction and; therapeutic use, mainly for killing cancerous cells.
27 Σεπ 2023 · Krypton-81m, a radioactive isotope of krypton, is used in nuclear medicine imaging techniques. It can be inhaled or injected to produce gamma radiation that can be detected and used for imaging certain organs, such as the lungs, heart, and brain.
Laser energy can be safely and effectively used for lithotripsy, for the treatment of various types of cancer, for a multitude of cosmetic and reconstructive procedures, and for the ablation of abnormal conductive pathways.
Lasers are used in Western medicine primarily for their thermal effect. In a laser, intensive electromagnetic energy can be concentrated within a very small area, producing a burning or cutting effect, which can be utilised for various diagnoses and surgical procedures.
Krypton-81m is ideally suited for lung ventilation studies. It has very short half-life and results in a low radiation burden for the patient. With gamma energy higher than that of 99m Tc, it enables lung ventilation studies to be performed immediately after a perfusion study of the pulmonary vascular bed. Marika Bajc MD, PhD, ...
