Interventional radiology uses imaging technologies such as x-rays, fluoroscopies, MRIs, ultrasounds, and CT scans as guidance for diagnosis and treatment.
X-ray imaging creates pictures using a small amount of electromagnetic. Doctors use the x-ray in interventional radiology to monitor patients before and after procedures.
Fluoroscopy is a real time x-ray to monitor and guide the positioning of probes, needles and catheters. A contrast "dye" is often used to guide us through the body.
Magnetic resonance imaging (MRI) is an imaging technique that uses a powerful magnetic field and radio waves to produce pictures of the body for the doctors to diagnose, monitor, and treat health conditions in order for doctors to biopsy legions that aren't visible with other imaging technologies.
Ultrasound is used to create images of the body including tendons, muscles, joints, blood vessels, and internal organs. Interventional Radiologists use real time ultrasounds to guide needles and probes to appropriate locations.
Computerized tomography, often referred to as a CT scan, is an imaging technique that uses multiple x-rays at different angles to reconstruct the internal structures of the body to enable safe insertion of needles and probes avoiding vital structures like blood vessels and vital organs.
