Radiation Therapy uses ionizing radiation, generally as part of cancer treatment, to control or kill malignant cells. Radiation Therapy is applied to the cancerous tumor because of the former's ability to control cell growth. The subspecialty of oncology that focuses on radiotherapy is called Radiation Oncology. Contrasted Radiology refers to a chemical substance which is introduced in the human body via entral/parentral route to visualize certain structures not seen in plain radiography. Since different parts of the body block the X-rays in various degrees, Contrasted Radiology is a method of studying the organs through X-rays by the administration of a special dye called contrast medium.
Because Contrasted Radiology is an effective tool for detecting and diagnosing disease, medical science has come up with different advanced varieties of Contrasted Radiology procedures. Various types of Contrasted Radiology exams are given for different reasons such as Intravenous Pyelography, Upper GI, Angiography, and Cardiac Catheterization, among others.
It is important to note that while Contrasted Radiology is effective, it does involve exposure to radiation. In addition, some discomfort is associated with various Contrasted Radiology exams, but it is usually minor.
