Interventional Radiology
Interventional radiology is the future of science. Rather than cutting people open and performing invasive surgery that lands patients in the hospital for weeks on end, minimally-invasive procedures using small tools and imaging technology are on the rise. These procedures have helped millions of patients who suffer from heart and lung trouble, cancers, strokes, aneurysms, nerve blocks, uterine fibroids and varicose veins, to name a few. Radiology is also important in assessing a person’s need for either minimally invasive procedures or larger surgery.
There are many procedures that medical professionals use to help patients in need. “Nonsurgical Uterine Fibroid Embolization is truly a major advance in women’s health,” writes Brian F. Stainken M.D., Society of Interventional Radiology President. With uterine fibroid embolization, a specialist uses a radiology MRI scan to check the status of the growth on the uterus. The procedure then involves blocking the blood vessels that deliver blood to the fibroid tumors, thus causing them to die and symptoms to subside. Radiologist Scott C. Goodwin says, “Uterine Fibroid Embolization is a safe, effective and minimally invasive option for women to consider. This is especially significant news for the more than 300,000 women who have hysterectomies performed annually in the United States to treat symptomatic uterine fibroids.”
Stent-assisted coil embolization is another procedure used in interventional radiology. “Our study shows that stent-assisted coil embolization is a feasible treatment option for ruptured brain aneurysms that are difficult to treat surgically or with balloon-assisted embolization,” reports Olli Tähtinen M.D. of Finland’s Tampere University Hospital. He says that stent-assisted embolization is ideal for critically ill patients. In the US, embolization is the preferred treatment for ruptured aneurysms (compared to surgery), but it can be extremely challenging when the width of the bulge is particularly large. Using metal coils and a balloon has shown to make the procedure easier, Finnish radiologists noted.
In addition to treating certain conditions, Interventional radiology also diagnoses patients. For instance, with an angiography, imaging investigates the blood vessels using contrast media, CO2 gas and computers. Cancer, heart trouble, organ failure, strokes, internal bleeding, aneurysms and a number of other conditions can be revealed using diagnostic radiology tools like ultrasound, computed tomography, fluoroscopy and magnetic resonance imaging. The outlook for jobs in this specialized field are plentiful for medical students who want to ride the crest of a growing trend.
