The results of histological or cytological analysis, or proof of benign disease on radiological follow-up, were considered the gold standard and were correlated with the findings of the integrated PET-CT in order to obtain sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of integrated PETCT.
All but one of the 25 scans read as negative were confirmed negative by histopathology, for a negative predictive value of 96%.
Major finding: At one illustrative cut point, the score would have reduced the number of biopsies by 41%, with a negative predictive value of 97%.
25% sensitivity, 85% negative predictive value, and 67.
This led to a drop in negative predictive value from a mean of 96% to 77%.
They noted that the sensitivity and negative predictive value of FFRCT were high, indicating a low rate of false-negative studies.
1,3-5,7-11) These reference values are critically important as they are used to score laboratory performance; in multitissue samples, such as TMAs, they can be used to calculate agreement rates, test sensitivity, specificity, positive predictive value, negative predictive value, and [kappa] values.
4%, respectively, with a positive and negative predictive value of 89% and 73%.
The primary objective of this study was to calculate the sensitivity, specificity, negative predictive value, and positive predictive value of a four-cut sinus CT scan, with the gold standard being the complete sinus CT scan.
Negative predictive value (also known as predictive value of a negative result) is defined as the proportion of patients who test negative and who do not have the disease (true negatives) among all patients with negative test results.
In the study, the test had a positive predictive value of 75% (75% of patients with positive test results were found to have cancer by biopsy), and a negative predictive value of 84% (84% of patients with negative test results were found to be cancer-free by biopsy) in men having a PSA level of 2.
