RATIONALE AND OBJECTIVES To examine a statistical validation method based on the spatial overlap between two sets of segmentations of the same anatomy. MATERIALS AND METHODS The Dice similarity… Expand
Receiver-Operating Characteristic Analysis for Evaluating Diagnostic Tests and Predictive Models
Receiver-operating characteristic (ROC) analysis was originally developed during World War II to analyze classification accuracy in differentiating signal from noise in radar detection.1 Recently,… Expand
Correlation and simple linear regression.
In this tutorial article, the concepts of correlation and regression are reviewed and demonstrated. The authors review and compare two correlation coefficients, the Pearson correlation coefficient… Expand
Etiology of spontaneous perirenal hemorrhage: a meta-analysis.
PURPOSE We determine the most common etiology of spontaneous perirenal hemorrhage. MATERIALS AND METHODS A MEDLINE search of the English language literature from 1985 to 1999 revealed 47… Expand
Detection of prostate cancer by integration of line-scan diffusion, T2-mapping and T2-weighted magnetic resonance imaging; a multichannel statistical classifier.
A multichannel statistical classifier for detecting prostate cancer was developed and validated by combining information from three different magnetic resonance (MR) methodologies: T2-weighted,… Expand
A MODIFIED CT SEVERITY INDEX FOR EVALUATING ACUTE PANCREATITIS: IMPROVED CORRELATION WITH PATIENT OUTCOME.
CT fluoroscopy-guided abdominal interventions: techniques, results, and radiation exposure.
PURPOSE To evaluate the benefits of computed tomographic (CT) fluoroscopy-guided interventions and assess radiation exposures incurred with CT fluoroscopy. MATERIALS AND METHODS A 6-month period of… Expand
Staging of advanced ovarian cancer: comparison of imaging modalities--report from the Radiological Diagnostic Oncology Group.
PURPOSE To compare ultrasonography (US), magnetic resonance (MR) imaging, and computed tomography (CT) for diagnosing and staging advanced ovarian cancer. MATERIALS AND METHODS US, CT, and MR… Expand
