Some patients are given baking soda crystals to create gas, extending the GI and creating a more defined image. Advantages of Fluoroscopy • • Minimally invasive diagnostic method – Decreases length of hospital stay – Cut hospitalization and anesthesia charges Less soft tissue damage during surgery because of the increased view and detail that the fluoroscopy gives. Limitations • • • Amount of radiation you can be safely exposed to. High degree of technological knowledge of the system is required to operate safely and effectively.
