Nuclear Radiology: An Effective Imaging Technique to Diagnose Fatal Diseases
Radiology is a special branch of medicine which deals with the study and application of imaging technology. This treatment method includes X-ray and radiation technology to diagnose several diseases including cancer. Radiologists use a number of imaging technologies such as ultrasound, computed tomography (CT), position emission tomography (PET), nuclear medicine and magnetic resonance imaging (MRI) to treat diseases. It is a minimally invasive medical procedure where interventional radiologists perform treatment with the help of imaging technologies.
In the treatment through nuclear radiology, radiologists use nuclear medicine (isotopes or radionuclides) and rely on the process of radioactive decay in the diagnosis of disease. Here radionuclides are combined with other chemical compounds to form radiopharmaceuticals. Once these radiopharmaceuticals are administered to the patient, they can localize to specific organs or cellular receptors. These radiopharmaceuticals enable to diagnose a disease based on the cellular function and physiology rather that anatomy.
In nuclear medicine imaging, doctors commonly use Technetium-99m, Iodine-131, Thallium-201 and Gallium-67. With the help of this technique, the organs like heart, thyroid, lung, gallbladder, bones, and liver can easily be evaluated for particular conditions. It can also be used to display excretory function of the kidney, blood flow of heart muscle iodine concentrating ability of thyroid, etc. The main principle imaging device is the gamma camera which suitably detects the radiation emitted by the tracer in the body and displays its image. The images taken from nuclear medicine can be combined with a CT scan taken quasi-simultaneously that help to improve diagnostic accuracy. So, patient can find an effective as well as accessible treatment through nuclear radiology.
