The mean age (SD) of the overall cohort was 49 ± 11 years, and all 179 of the patients were women (Table 1). The details of the overall pathologic distribution and of each cohort are presented in Additional file 1: Table S5. The frequencies of the PFB-CEUS and MP-MRI ...
Comparison of both index tests (Table4), which was the major objective of this study, revealed that there was no overall statistically significant difference between index tests for clinical sensitivity, clinical specificity, PPV, NPV, false positive rate nor accuracy, either for T21, T18, T13 ...

The paired t-test results are presented in Table 1. As shown in Table 1, significant differences between the screen angles according to the head loss values were found for all scenarios. Consequently, the results confirm that the screen angle is a valuable element in practical applications, and...
The operating temperature of tungsten cathodes is between 2200 and 2500 K. The work function at the lowest operating temperature is rather high (see Table 4.5). The advantage of running the cathode at such temperatures is that contaminating electronegative gases are rapidly evaporated, hence their ...
