Comparison of delivered and residual Technetium labeled Diethylenetriamine-pentaacetic acid when ventilating: corrugated vs. non-corrugated tubing.

Conclusions: This study proved that after ventilation, the non-corrugated tubing retained 149.7% less counts when compared to the corrugated tubing. In addition, the ambu bag attached to the non-corrugated tubing retained 119.2% more counts than the ambu bag attached to the corrugated tubing. A higher amount of Tc-DTPA delivered to the lungs would allow for a lower prescribed dose, while keeping the same image sensitivity. Further research should be conducted to see how much the prescribed dose of Tc-DTPA may be reduced to keep patient radiation exposure as low as reasonably achievable.
