Study Notes
Fluoroscopy in Radiology
Definition
- Fluoroscopy is a type of medical imaging that uses continuous X-ray beams to guide diagnostic and therapeutic procedures.
Principle
- Fluoroscopy works by transmitting X-ray beams through the body, which are then detected by a digital image receptor or an image intensifier.
- The resulting images are displayed on a monitor, allowing the operator to visualize internal structures in real-time.
Applications
- Guiding interventional procedures:
- Angiography and angioplasty
- Biopsy and tumor treatment
- Pain management procedures
- Diagnostic imaging:
- Swallowing studies (e.g., barium swallows)
- Upper GI series
- Voiding cystourethrograms
- Orthopedic and musculoskeletal procedures:
- Guiding joint injections and aspirations
- Reduction of fractures and dislocations
Advantages
- Real-time imaging allows for precise guidance during procedures
- Enables dynamic assessment of anatomical structures and physiological processes
- Can reduce procedure time and radiation exposure
Limitations
- Higher radiation exposure compared to other imaging modalities
- Requires specialized equipment and trained operators
- Image quality may be affected by patient size, motion, and anatomical complexity
Radiation Safety
- Fluoroscopy operators must follow radiation safety guidelines to minimize exposure to patients, staff, and themselves.
- Techniques to reduce radiation exposure include:
- Using lowest possible X-ray beam intensity
- Limiting fluoroscopy time
- Using shielding and Protective Equipment
Digital Fluoroscopy
- Digital fluoroscopy systems use digital image receptors and computer algorithms to process and display images.
- Advantages over traditional fluoroscopy:
- Improved image quality and resolution
- Reduced radiation exposure
- Ability to store and review images electronically
