to interpret and utilize medical imaging technology to diagnose and treat many different types of diseases and disorders throughout the body, for example, determining the severity of injuries or discovering tumors.
Radiology is a medical specialty that utilizes a variety of medical imaging techniques to diagnose and treat diseases such as cancer. Within radiology there are many subspecialties or areas, including emergency radiology, gastrointestinal radiology, cardiovascular radiology, breast imaging, interventional radiology and nuclear radiology, among others. Radiologists are trained physicians capable of performing image-guided, minimally invasive procedures to either diagnose or treat certain diseases – treatment techniques provided are often an alternative to other surgical methods.
In the diagnosis of disease, radiologists are trained to safely perform radiation based-imaging, including magnetic resonance imaging (MRI), fluoroscopies, X-rays (protectional radiographs), computed tomography (CT) scans, ultrasound and nuclear medicine imaging techniques, among others. These imaging techniques allow radiologists to interpret and diagnose diseases such as cancer by identifying malignant growths of tumors that would otherwise go unnoticed or undiagnosed.
When radiologists provide patients with treatment options for diseases, they are able to offer less invasive, highly targeted procedures that will often replace more invasive and/or painful surgeries. For example, treatment benefits in interventional radiology usually include less risk, no large incisions, shorter recovery times, less pain and sometimes a lower cost.
