Rationale and Objectives The purpose of this study was to determine textural features that show a significant difference between carcinomatous tissue and the bladder wall on magnetic resonance ima...

Rationale and Objectives To develop an automated computed tomography angiography (CTA) imaging protocol that allows visualization of the whole brain vasculature and evaluate the clinical usefulnes...

Rationale and Objectives The aim of this study was to develop a computerized scheme for automated identity recognition based on chest radiograph features. Materials and Methods The proposed meth...

Long-awaited third edition of the Arthritis in Black and White has finally arrived. The second edition was published in 1997 and remains a classic “must-read” textbook for radiologists-in-training....

Rationale and Objectives Traditional two-class receiver operating characteristic (ROC) analysis is inadequate for the complete evaluation of observer performance in tasks with more than two classe...

Rationale and Objectives The purpose of this investigation is to compare the statistical power of the most common measure of performance for observer performance studies, area under the ROC curve ...

Rational and Objectives Receiver operating characteristic (ROC) analysis is often used to find the optimal combination of biomarkers. When the subject level covariates affect the magnitude and/or ...

This issue of Academic Radiology is the second of two issues honoring the memory of Dr. Charles E. Metz, who pioneered the application of receiver operating characteristic (ROC) analysis for evalua...

Rationale and Objectives Based on imaging features, the optimal thresholds are typically determined as cutoff points to dichotomize the corresponding measurement scales. Materials and Methods Fi...

Rationale and Objectives Human observers often do not produce empirical operating points near the northeast corner of the receiver operating characteristic (ROC) plot, and thus the local shape of ...
