Applications of Radiology in Contemporary Medical Science
Radiology refers to studying images of human body with the help of radiant energy. Radiologists are involved in interpretation of radiological images for diagnosis and treatment of diseases. They offer assistance to physicians while carrying on a diagnosis.
Originally, the field involved the usage of radiological devices or X-rays in medical imaging. However, the field has witnessed immense expansion. Today, radiology incorporates radioactive, magnetic and high frequency sound imaging. Presently, the technologies utilized by radiologists include nuclear medicine, magnetic resonance imaging (MRI), computed tomography (CT or CAT), positron emission tomography (PET), and ultrasound as well as computed tomography (CAT/CT).
Fluoroscopes and X-rays are deployed for diagnosis of broken bones, bone tumors as well as other problems related to internal organs. PET employs radiotracer for emission of gamma rays. MRI technology facilitates in focusing radiations on smaller body parts by utilizing super-cooled magnets. At times, CT, MRI and PET could be utilized together for providing a combination of images thereby enabling an accurate diagnosis.
Radiology can also be utilized for destruction of cancerous cells by means of targeted radiation that utilize radionuclides. The radiations could be administered internally or externally through a machine. Such high-energy radiations enable in preventing the growth of cancerous cells.
Hospitals consult the radiology groups for obtaining information that could be useful in treatment or diagnosis. However, such services are usually outsourced. Outsourcing is considered cost-effective as well as time-saving. However care should be taken that the outsourcing is done to a centre that is well qualified as well competent enough to deliver authentic reports and that too on time.
