9 Fig 8 Effects of magnification on radiation scatter exposure to the operator, assistant, and anesthesiologist in digital subtraction angiography (DSA) imaging. The increased utility of endovascular procedures has exposed interventionalists to potentially high levels of occupational radiation. This study demonstrates that the magnitude and distribution of scatter radiation can be measured to the operator, assistant, and anesthesiologist under various fluoroscopic imaging conditions and techniques. Knowledge of the various angiographic parameters and their impact in scatter radiation levels can help operators utilize the dose reduction techniques and incorporate them in their routine practices.
