Among the orientation candidates chosen from the convex hull of a model, the best orientation is selected using the simple additive weighting method, a widely used multi-criterion method for decision making.
Therefore, we have suggested that improved intraoperative in situ identification of F-FDG-avid tissue sites can be accomplished by the use of the three-sigma statistical threshold criteria method for determination of gamma detection probe positivity [ 2].
In that regard, as based upon categorical variable comparison of the K-alpha probe as a function of the specific threshold criteria used, we specifically found that the three-sigma statistical threshold criteria method was significantly better than the ratiometric threshold criteria method for determining probe positivity for the K-alpha probe (P = 0.050).
The purpose of our study was to evaluate the 1.5-to-1 ratiometric threshold criteria method versus the three-sigma statistical threshold criteria method for determination of gamma detection probe positivity for intraoperative in situ identification of presumed abnormal F-FDG-avid tissue sites in a manner that was independent of the specific type of gamma detection probe used.
The three-sigma statistical threshold criteria method was significantly better than the 1.5-to-1 ratiometric threshold criteria method for determination of gamma detection probe positivity for intraoperative in situ detection of presumed abnormal F-FDG-avid tissue sites during radioguided oncologic surgery.
In the current report, we evaluated the probe counting efficiency and the success rate of in situ intraoperative detection of F-FDG-avid tissue sites (using the three-sigma statistical threshold criteria method and the ratiometric threshold criteria method) for three gamma detection probe systems tested during F-FDG-directed surgery.
The purpose of our study was to evaluate the counting efficiency and the success rate of in situ intraoperative detection of F-FDG-avid tissue sites (using the three-sigma statistical threshold criteria method and the ratiometric threshold criteria method) for three different gamma detection probe systems.
Nevertheless, due to the small sample size of our limited data set that was available for the 2 × 3 contingency table analysis, there was no significant difference in our statistical analysis of overall comparison of the three gamma detection probe systems utilized as a function of the specific threshold criteria method for the determination of gamma detection probe positivity [ 2].
