Radiology As A Field Of Science
Radiology is a large subspecialty of medical science that includes several smaller branches. A radiologist receives training in all the branches of radiology. However, there are certain disciplines or subspecialty in both diagnostic as well as interventional radiology. For instance, musculoskeletal radiology deals with imaging of muscles and joints as well as bones. Likewise, mammography deals with the imaging of breast tissue.
While talking about therapeutic radiology, we are referring to radiation therapy. This therapy is mostly utilized for treatment of cancers and tumors. During the procedure, specific quantity of radiation is administered. This helps to control the reproduction of cancer cells in human body. Generally, this field is identified as radiotherapy.
Interventional radiology describes that subspecialty of radiology wherein minimally invasive procedures are conducted with the help of image guidance. These procedures are conducted for treatment and vascular diseases. Hence, there is a separate branch of interventional radiology called vascular interventional radiology. While some of the procedures are conducted for the purpose of diagnosis. (Example: Angiogram), certain other procedures are performed for the purpose of treatment (Example: Angioplasty). During these procedures, images are utilized for guiding. Such procedures are usually performed with the help of a needle or any other instrument such as catheters (small tubes). The images offer a road map which allows the radiologist to guide the instruments to the diseased areas.
Vascular interventional radiology as well as non vascular interventional radiology provides state of the art, minimally invasive image guided therapeutic and diagnostic care for a variety of vascular and nonvascular conditions affecting the abdomen, chest as well as extremities.
