The Technological Advancement Ensures A Bright Future For Interventional Radiology
Interventional radiology (IR) is a subspecialty of radiology in which physicians perform minimally invasive treatment procedures with the help of image guidance. The future of interventional radiology treatments is very bright that promises to care a variety of conditions by offering less risk, less pain and less recovery time, compared to open surgery. The treatment procedures are done for purely for diagnosis purposes. In the wide sense, this biological imaging involves radiology, nuclear medicine, investigative radiological sciences, endoscopy, thermography, microscopy and medical photography.
Images taken by IR guide to inject needles or other tiny instrument like small tubes called catheters. These pictures provide road maps to interventional radiologists. The common interventional imaging modalities include computed tomography, fluoroscopy, ultrasound, and magnetic resonance imaging (MRI). Fluoroscopy and computed tomography use ionizing radiation that may be potentially harmful to the patient as well as to the interventional radiologist. MRI provides superior tissue contrast. However, this technology is an expensive and requires specialized instruments. However, ultrasound suffers from image quality and tissue contrast problems, but it is a fast and inexpensive imaging technology. The 2D techniques cost low in comparison to the 3D tomography.
Generally, Interventional radiologists are board-certified and fellowship trained physicians who provide their expertise in minimally invasive, targeted treatments. These experts carry a comprehensive knowledge of the advance and least invasive treatments. They also undergo the specialized training certified by the American Board of Medical Specialties. The common IR procedures include angiography, balloon angiography/stent, cholecystostomy, drain insertion, embolization, radiofrequency ablation, IVC filters, nephrostomy placement. In future, interventional radiology is going to see some more advancement in the technological infusion.
