Time-to-event endpoints are widely used as measures of patients' well-being and indicators of prognosis. In imaging-based biomarker studies, there are increasingly more studies that focus on examining imaging biomarkers' prognostic or predictive utilities on those endpoints, whether in a trial or an observational study setting. In this educational review...
Background The diagnostic value of carotid plaque characteristics based on higher–resolution vessel wall MRI (HRVW-MRI) combined with white matter lesion (WML) burden for the risk of ischemic stroke is unclear. Purpose To combine carotid plaque features and WML burden to construct a hybrid model for evaluating ischemic stroke severity and prognosis...
Background Clear cell likelihood score (ccLS) is reliable for diagnosing small renal masses (SRMs). However, the diagnostic value of Clear cell likelihood score version 1.0 (ccLS v1.0) and v2.0 for common subtypes of SRMs might be a potential score extension. Purpose To compare the diagnostic performance and interobserver agreement of ccLS v1.0 and...
Background The use of peritumoral features to determine the survival time of patients with rectal cancer (RC) is still imprecise. Purpose To explore the correlation between intratumoral, peritumoral and combined features, and overall survival (OS). Study Type Retrospective. Population One hundred sixty-six RC patients (53 women, 113 men; average...

Background Radiomics models trained on data from one center typically show a decline of performance when applied to data from external centers, hindering their introduction into large-scale clinical practice. Current expert recommendations suggest to use only reproducible radiomics features isolated by multiscanner test–retest experiments, which might...
