Radiology involves the study of images of internal organs of a living human body. A Radiologist is a physician who reads the results of various radiology exams. Before the arrival of diagnostic imaging, it was only a patient's death that allowed doctors to study the internal organs of the human body.
Radiology was originally a branch of medical imaging, X-rays are used in large flat sheets of photographic films for diagnosis. Modern day radiology practice is no longer limited to x-rays and now covers other methods of beam diagnostics such as computed tomography (CT), magnetic resonance imaging (MRI) and ultrasound. Unlike other fields of radiology, MRI and ultrasound have a separate method of diagnostic imaging, which does not involve the use of ionizing radiation.
Magnetic resonance imaging of non-invasive diagnostic method that combines a large powerful magnetic field, radio frequency, look to the human body, without the use of X-rays. This type of radiation assuming that produce detailed images of organs, soft tissue, bone, and other internal structures of the body without the use of ionizing radiation. Detailed MRI allows physicians to better appreciate the body parts and some diseases that can not be assessed adequately with other imaging techniques such as X-ray or computed tomography. MRI scans produce the highest quality of soft tissue contrast of all other forms of diagnostic imaging and is especially beneficial for the imaging of the brain, spine and musculosketal system.
