Fluoroscopy/Interventional Radiology
September 30, 2016
Fluoroscopy uses x-rays to display live images in real time on a computer screen. The technology also acquires x-ray movie clips of the procedure. This dynamic evaluation of a patient, allows us to image a region of interest continuously, while simultaneously watching on the screen. The machine, called a C-arm, also allows for rotation around the patient so that images can be obtained from any angle.
Examples of studies performed in fluoroscopy include:
- Airway evaluation – eg. for tracheal collapse
- Swallowing studies (esophagography)
- Contrast (dye) studies – eg. of the urinary tract
Flouroscopy is also used for minimally invasive or interventional treatment options as well. These procedures include:
- Tracheal stent
- Urethral stent
- Pacemaker implantation
- Balloon Valvuloplasty – Eg. For Pulmonic stenosis
- Repair of Patent Ductus Arteriosus (PDA)
- Biopsy and Needle aspirates
A pacemaker has been implanted into the right ventricle of the heart under flouroscopic guidance.
