Risk prediction of cerebrovascular events with carotid plaque magneitc resonance analysis: A meta-analysis.

Background And Purpose: It is not conclusive that magnetic resonance (MR)-based carotid atherosclerotic plaque assessment identifies high-risk features associated with cerebrovascular events. We aimed to systematically summarize the association of MR imaging (MRI)-determined intraplaque hemorrhage (IPH), lipid-rich necrotic core (LRNC), and thinning/rupture of the fibrous cap (TRFC) with subsequent ischemic events.

Materials And Methods: We performed a comprehensive literature search evaluating the association of MRI-based carotid plaque composition with ischemic outcomes.

Prognostic significance of late gadolinium enhancement on cardiac magnetic resonance in patients with hypertrophic cardiomyopathy.

Background: Late gadolinium enhancement (LGE) on cardiac MRI indicates the myocardial fibrosis in hypertrophic cardiomyopathy (HCM), and the prognostic value of LGE in HCM has been described in several studies, but controversy exists given the limited power of these studies to predict future adverse cardiac events. The objective of this study was to perform a meta-analysis to systematically evaluate the predictive value of LGE on cardiac magnetic resonance (CMR) for future adverse cardiac events.

Methods: We systematically searched multiple database including PubMed, EMBASE, and Cochrane Library for cohort studies of the effects of LGE on clinical outcomes (sudden cardiac death (SCD)/aborted SCD, all cardiac death, and all-cause mortality) in patients with HCM.

Diagnostic and clinical utility of dynamic contrast-enhanced MR imaging in indeterminate pulmonary nodules: a metaanalysis.

Objective: This study aims to perform a metaanalysis to assess the diagnostic performance and clinical utility of the dynamic magnetic resonance imaging (MRI) in discrimination of benign and malignant pulmonary nodules.

Materials And Methods: We searched PubMed, EMBASE, and Cochrane Library from January 1995 to May 2015 for studies evaluating the diagnostic accuracy of dynamic MRI in discriminating benign from malignant pulmonary nodules. Methodological quality was assessed by the Quality Assessment of Diagnostic Accuracy Studies-2.
