Background Compression ultrasonography (CUS) is the first-line imaging test in the diagnostic management of suspected deep vein thrombosis (DVT) of the lower extremity. Three CUS strategies are used in clinical practice. However, their relative diagnostic accuracy is uncertain. Objectives This systematic review and meta-analysis aimed to summarize and compare the diagnostic accuracy of single limited, serial limited, and whole-leg CUS for DVT. Methods MEDLINE, Embase, and CENTRAL were searched f...

Uric acid stone diagnosis is presently done primarily with in vitro analysis of stones. In vivo diagnosis with dual-energy CT (DECT) would allow earlier initiation of therapy with urine alkalinization and avoid surgical intervention. To evaluate if DECT, using stone analysis as reference standard, is sufficiently accurate to replace stone analysis for diagnosis of uric acid stones. Original studies in patients with urolithiasis examined with DECT with stone analysis as the reference standard wer...

Objective To evaluate whether imaging diagnostic test accuracy conference abstracts with positive conclusions or titles are more likely to reach full-text publication than those with negative (or neutral) conclusions or titles.

Reporting standards in biomedical research have been shown to be suboptimal. The publication of the PRISMA statement has improved the completeness of reporting of systematic reviews, but several issues specific to diagnostic test accuracy are not included in the PRISMA statement. Therefore, a diagnostic test accuracy extension of the PRISMA statement, PRISMA-DTA, was created. This commentary addresses completeness of reporting in systematic reviews, the PRISMA-DTA statement, and strategies for o...

Publication bias related to positive results may be less of a problem in diagnostic accuracy research than in evaluation of interventions; however, considering many studies fail to become peer-revi...

Objectives To assess the risk of citation bias in imaging diagnostic accuracy research by evaluating whether studies with higher accuracy estimates are cited more frequently than those with lower accuracy estimates.

Suboptimal reporting in the publication of imaging research studies is a growing concern. Deficient and incomplete reporting prevents the evaluation of the validity, replicability, and the overall quality of the research. Reporting guidelines are checklists designed to guide researchers about the minimum information to be provided in research studies to allow for adequate quality appraisal and to assess generalizability. They are a powerful tool to allow key stakeholders such as journal editors,...
