Accuracy In Treatment Comes Through Diagnostic Radiology Interventional Methods
Interventional radiology or vascular interventional radiology refers to a subspecialty of radiology under which we perform minimally invasive procedures with the help of image guidance. Many of such procedures are used for diagnostic purposes as well as treatment purposes. Through the diagnostic radiology interventional procedure, the images are used for the procedures to direct needles or other tiny instruments like small tubes/ catheters. These images are very helpful in allowing interventional radiologist to guide these instruments through the body during treatment procedures.
There are some common diagnostic interventional radiologic modalities that include fluoroscopy, ultrasound, magnetic resonance imaging (MRI), and computed tomography (CT). Fluoroscopy and CT use ionizing radiation to extract more crystal clear images. These methods have advantages of being fast and geometrically accurate, while ultrasound is not enough to provide quality image and suffers tissue contrast problems. The magnetic resonance imaging method provides superior tissue contrast with the help of specialized instruments. Though, some of these diagnostic radiology interventional modalities are expensive but they promise much to the diagnostic purposes.
Some of the common interventional radiology procedures are angiography, chemoembolization, cholecystostomy, drain insertions, embolization, balloon angiography/stent, etc. This branch is a very useful development in the guided techniques and now interventional radiologic procedure is seen as a good replacement of the surgery. The catheter direction and image guidance is safer, less painful, quicker recovery time, minimal invasive, shorter hospital for patients. A diagnostic interventional radiologist is a physician who receives special training to treat and diagnose and treat conditions by using miniaturized catheters through image guidance.
