Interventional radiology; Diagnostic radiology; X-ray imaging
Radiology is a branch of medicine that uses imaging technology to diagnose and treat disease.
Radiology may be divided into two different areas, diagnostic radiology and interventional radiology. Doctors who specialize in radiology are called radiologists.
Diagnostic radiology helps health care providers see structures inside your body. Doctors that specialize in the interpretation of these images are called diagnostic radiologists. Using the diagnostic images, the radiologist or other physicians can often:
The most common types of diagnostic radiology exams include:
Interventional radiologists are doctors that use imaging such as CT, ultrasound, MRI, and fluoroscopy to help guide procedures. The imaging is helpful to the doctor when inserting catheters, wires, and other small instruments and tools into your body. This typically allows for smaller incisions (cuts).
Doctors can use this technology to detect or treat conditions in almost any part of the body instead of directly looking inside of your body through a scope (camera) or with open surgery.
Interventional radiologists often are involved in treating cancers or tumors, blockages in the arteries and veins, fibroids in the uterus, back pain, liver problems, and kidney problems.
The doctor will make no incision or only a very small one. You rarely need to stay in the hospital after the procedure. Most people need only moderate sedation (medicines to help you relax).
