Studies of diagnostic test accuracy

Definition of a diagnostic test accuracy study? o A diagnostic test accuracy study evaluates the accuracy of index test in correctly distinguishing between those with disease and those without disease compared to gold standard test. o Gold standard test is also called criterion test or reference test. o For a diagnostic test to be accurate, it should be both valid (accuracy) and reliable (preci...

Diagnostic Accuracy of Positron Emission Mammography with 18F-fluorodeoxyglucose in Breast Cancer Tumor of Less than 20 mm in Size

Objective(s): To investigate the diagnostic accuracy of positron emission mammography (PEM) and positron emission tomography/computed tomography (PET/CT) for small breast tumors of less than 20 mm in size.Methods: The study was conducted on a total of 100 subjects (i.e., 50 patients with pathologically proven breast cancer and 50 normal cases of medical screening). The total number of tumors wa...

diagnostic accuracy of coronary calcium score less than 100 in excluding coronary artery disease

conclusion we conclude that coronary calcium scoring provided useful information in the management of patients. in cacs less than 100, it has a npv of 87% in excluding significant stenosis in patients with the risk of cad but it does not have enough diagnostic accuracy for surely excluding coronary stenosis, so we should perform a combination of cacs and coronary ct angiography for patients. re...

Cochrane diagnostic test accuracy reviews

In 1996, shortly after the founding of The Cochrane Collaboration, leading figures in test evaluation research established a Methods Group to focus on the relatively new and rapidly evolving methods for the systematic review of studies of diagnostic tests. Seven years later, the Collaboration decided it was time to develop a publication format and methodology for Diagnostic Test Accuracy (DTA) ...
