Radiology is the science that uses medical imaging to diagnose and sometimes also treat diseases within the body. A variety of imaging techniques such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine including positron emission tomography (PET), and magnetic resonance imaging (MRI) are used to diagnose and/or treat diseases.
Interventional radiology is the performance of (usually minimally invasive) medical procedures with the guidance of imaging technologies. Our advanced technology helps us in the identification and treating the diseases in the body thereby providing disease-free happy patient history.
Radiography is an imaging technique using X-rays to view the internal structure of an object. To create the image, a beam of X-rays, a form of electromagnetic radiation, is produced by an X-ray generator and are projected toward the object. A certain amount of X-ray is absorbed by the object, dependent on its density and composition. The X-rays that pass through the object are captured behind the object by a detector (either photographic film or a digital detector). The generation of flat two-dimensional images by this technique is called projection radiography.
Medical ultrasound (also known as diagnostic sonography or ultrasonography) is a diagnostic imaging technique based on the application of ultrasound. It is used to see internal body structures such as tendons, muscles, joints, blood vessels and internal organs. Its aim is often to find a source of a disease or to exclude any pathology. The practice of examining pregnant women using ultrasound is called obstetric ultrasound and is widely used.
Clinical magnetic resonance imaging (clinical MRI) is an imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease. MRI scanners use strong magnetic fields, radio waves, and field gradients to generate images of the organs in the body. MRI does not involve x-rays, which distinguishes it from computed tomography (CT or CAT).
A CT scan, also known as computed tomography scan, makes use of computer-processed combinations of many X-ray measurements taken from different angles to produce cross-sectional (tomographic) images (virtual "slices") of specific areas of a scanned object, allowing the user to see inside the object without cutting. Other terms include computed axial tomography (CAT scan) and computer-aided tomography.
Nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear medicine, in a sense, is "radiology did inside out" or "end radiology" because it records radiation emitting from within the body rather than radiation that is generated by external sources like X-rays.
