Study Summary
The PREFER II trial primary objective of the trial is to show how much radiation attenuation is provided by XPF thyroid collars in absolute and relative terms.
Primary Outcome
Radiation attenuation. The null hypothesis is that the XPF thyroid collar is equal to the standard 0.5mm Pb lead equivalent thyroid collar with regard to radiation attenuation/transmission in relative (%) terms. The alternative hypothesis is that the XPF thyroid collar is superior or inferior to the standard thyroid collar. Based on our results obtained during the 60 procedures (PREFER trial), 150 procedures are required to demonstrate a significant difference with an alpha level of 5% and a pow
Interventions
- DEVICE XPF thyroid collar
