We consider the power and sample size calculation of diagnostic studies with normally distributed multiple correlated test results. We derive test statistics and obtain power and sample size formulas. The methods are illustrated using an example of comparison of CT and PET scanner for detecting extr

Receiver operating characteristic (ROC) curves and their associated indices are valuable tools for the assessment of the accuracy of diagnostic tests. The area under the ROC curve is a popular summary measure of the accuracy of a test. The full area under the ROC curve, however, has been criticized

## Abstract Ultrasonic duplex scanning has a sensitivity of 97% in detecting disease of the carotid bulb. However, the specificity is much less, being 37%. The error in distinguishing normal arteries from those with minimal disease appears to be in part related to the size of the sample volume of t
