STUDY OBJECTIVE To assess the efficacy of the chest radiograph in identifying patients with miliary tuberculosis. DESIGN Retrospective case-controlled review by three independent blinded chest radiologists. SETTING Provincial tuberculosis control center. PATIENTS Population-based sample, including all proved cases of miliary tuberculosis diagnosed in the Province of British Columbia, Cana...

A histopathological index of contractility failure, which was reported to be accurate for the diagnosis of idiopathic dilated or congestive cardiomyopathy in Japan, was used to assess endomyocardial biopsy specimens from 41 Dutch patients with suspected dilated cardiomyopathy. The calculated index had a sensitivity of 62.5% and a specificity of 68% for idiopathic dilated or congestive cardiomyo...

Developing novel nuclear cardiology approaches requires evaluating their diagnostic ability. Statistical measures such as sensitivity, specificity, receiver operating characteristic (ROC) curve, and area under the curve (AUC) are useful to evaluate the diagnostic value of novel imaging parameters. This paper reviews key statistical methods used in the evaluation of diagnostic tests and highligh...

background endometrial carcinoma is a highly prevalent gynecologic malignancy. the international federation of gynecology and obstetrics (figo) staging system underwent significant revision on 2009. key changes in the figo staging system include simplification of stage i endometrial cancer and removal of cervical mucosal invasion as a separate stage. mri is a noninvasive diagnostic method for p...

background:the diagnostic accuracy of frozen section as an important source of information in surgical pathology is important not only in the management of surgical patients but also as a measure of quality control in surgical pathology. in this study, we evaluated the diagnostic accuracy of frozen sections over a 6-year period in a teaching hospital in iran. methods: we retrospectively review...

AIM This paper reports an investigation of the diagnostic accuracy of the Care Dependency Scale (CDS). BACKGROUND Assessment tools can be described in terms of diagnostic accuracy, or the ability to correctly classify subjects into clinically relevant subgroups. Diagnostic accuracy can be determined by several techniques as sensitivity, specificity, receiver operating curve analysis and likel...
