1. Among patients with vascular disease, high burden of atherosclerotic lesions in the posterior circulation as well as the posterior cerebral artery was associated with poorer memory and executive functioning. Evidence Rating Level: 2 (Good) The individual and societal burden of dementia continues to rise as the global population, on average,...
1. In this prospective cohort, MRI-targeted biopsies alone, underestimated the histologic grade of prostate cancer tumors. 2. The combination of MRI targeted biopsy and systematic biopsy led to greater detection of all prostate cancers, and the upgrade of tumors to grade 3 or higher on histopathological analysis, upon radical prostatectomy,...
1. In a systematic review and meta-analysis of the use of group II (low risk) gadolinium-based contrast agents (GBCA) for MRI in patients with stage 4 and 5 chronic kidney disease (CKD), there were no reported cases of nephrogenic systemic fibrosis (NSF). 2. The use of gadobenate dimeglumine, which is...

Gadolinium-based contrast material is typically used for follow-up imaging of patients with multiple sclerosis (MS) in order to detect new brain lesions. As magnetic resonance imaging (MRI) techniques have improved in recent years, however, the need for gadolinium-based contrast material in detecting new lesions is now in question. In...
Association Between the Development of Pediatric Voice Disorders and Singing in Children’s Choir Singing has been thought to be protective against the development of voice disorders in children; however, there have been few studies evaluating this. In this cohort study, investigators analyzed data from 752 singing and 743 non-singing children...
1. Patients with a legacy pacemaker or cardioverter-defibrillator were followed after undergoing medically indicated magnetic resonance imaging (MRI) examinations, and no long-term clinically significant adverse effects were reported. 2. The most common adverse event immediately after the MRI was power-on reset, which occurred at a rate of one out of...
1. This prospective cohort study of patients with cardiac pacemakers or implantable cardioverter-defibrillators (ICDs) undergoing magnetic resonance imaging (MRI) demonstrated no deaths, episodes of lead failure requiring immediate replacement, or loss of capture. 2. No adverse events were reported with repeated MRI scans. Evidence Rating Level: 2 (Good)        Study Rundown: There...
1. From a cohort study, stroke risk was increased eight-fold when lesions both small and large were observed using MRI. 2. The presence of small cerebrovascular lesions was associated with a three-fold higher risk for subsequent stroke compared with no lesions. Evidence Rating Level: 1 (Excellent) Study Rundown: Brain lesions identified on...

1. Among patients with acute neurologic deficits presenting within six hours of symptoms onset, diffusion-weight magnetic resonance imaging (DWI) was shown to be significantly more sensitive and specific for the diagnosis of ischemic stroke than non-contrast computed tomography (NCCT). Original Date of Publication: September 2002 Study Rundown: Thrombolysis is a widely...
