Introduction: A previous prospective, randomized controlled trial showed that animated videos shown to children before their magnetic resonance imaging (MRI) scan reduced the proportion of children needing repeated MRI sequences and improved confidence of staying still for at least 30 minutes. Children preferred the interactive video. We hypothesize that the interactive video is non-inferior to showing two videos (regular and interactive) in improving children’s cooperativeness during MRI scans. Methods: In this Institutional Review Board-approved prospective, randomized, non-inferiority trial, 558 children aged 3 to 20 scheduled for elective MRI scan from June 2017 to March 2019 were randomized into interactive video only and combined (regular and interactive) videos groups. Children were shown the videos before their scan. Repeated MRI sequences, general anesthesia (GA) requirement, and improvement in confidence of staying still for at least 30 minutes were assessed. Results: In the interactive video group (n = 277), 86 (31.0%) children needed repeated MRI sequences, 2 (0.7%) needed GA, and the proportion of children who had confidence in staying still for greater than 30 minutes increased by 22.1% after the video. In the combined videos group (n = 281), 102 (36.3%) children needed repeated MRI sequences, 6 (2.1%) needed GA, and the proportion of children who had confidence in staying still for greater than 30 minutes increased by 23.2% after videos, not significantly different from the interactive video group. Conclusion: The interactive video group demonstrated non-inferiority to the combined videos group.

Background: Vitamin A has immunomodulatory properties and may regulate the transcription of genes involved in remyelination. Objective: To investigate the association between retinol and disease activity in multiple sclerosis (MS). Methods: Cohort study of 88 relapsing–remitting MS patients, originally included in a randomised placebo-controlled trial of omega-3 fatty acids in MS (the OFAMS study), followed prospectively for 24 months with repeated assessments of serum-retinol and magnetic resonance imaging (MRI). All patients were initiated on interferon β-1a after month 6. Results: Each 1 µmol/L increase in serum-retinol reduced the odds (95% confidence interval) for new T1 gadolinium enhanced (Gd+) lesions by 49 (8–70)%, new T2 lesions by 42 (2–66)%, and combined unique activity (CUA) by 46 (3–68)% in simultaneous MRI scans, and 63 (25–82)% for new T1Gd+ lesions, 49 (3–73)% for new T2 lesions and 43 (12–71)% for CUA the subsequent month. Serum-retinol also predicted new T1Gd+ and T2 lesions six months ahead. The associations were not affected by HLA-DRB1*15, or serum levels of 25-hydroxyvitamin D, eicosapentaenoic acid or docosahexaenoic acid. Conclusion: Serum retinol is inversely associated with simultaneous and subsequent MRI outcomes in RRMS.

Background Magnetic Resonance imaging (MRI) in patients (pts) with MRI-conditional cardiovascular implantable electronic devices (CIED) remain a logistical issue for device programming during the scan. In current practice, a trained person needs to be present on-site to program CIED for MRI scan. This can cause delay in patient care, rescheduling of tests and increase healthcare costs. A novel remote programming (RP) strategy can be utilized to reprogram the CIED remotely. We sought to explore the feasibility and safety of RP of CIED’s in pts undergoing MRI scan. Methods We implemented the Medtronic CIED RP software at our institution after ensuring HIPAA compliance. The MRI technician started the session by contacting an off-site remote operator and placing a programmer wand from 2090 Medtronic programmer over CIED. The remote operator logged into a remote access software and provided a unique access code to the MRI technician. After entering the access code into the programmer, the remote operator was able to program the device as needed. We conducted a periodic audit of the first 209 pts who underwent RP of CIED’s for MRI. Outcomes analyzed were safety parameters during RP. Results Of the 209 MRI scans, 51 scans were performed urgently. There were no connectivity and programming problems or need for MRI rescheduling. In-person reprogramming was not required for any pt. All scans were completed safely in a timely manner, and there were no reports of CIED malfunction. Conclusions Remote programming of CIED’s for MRI scans is a safe and effective strategy.

We investigated if monthly gadolinium (Gd)-enhanced magnetic resonance imaging (MRI) can assist the clinician in anticipating the diagnosis of multiple sclerosis (MS) in the very first few months following a clinically isolated syndrome (CIS). A consecutive series of CIS patients with ≥ 3 T2-weighted (T2W) hyperintense brain MRI lesions suggestive of MS were followed up for the first six consecutive months after enrollment with monthly triple-dose Gd-enhanced brain MRI scan. MRI conversion to MS was defined by the presence of either ≥ 1 new Gd-enhancing lesion or ≥ 1 new T2W lesions in the subsequent MRI scan. Sixty patients were included. Of them, 30 (50%) had at least one Gd-enhancing lesion on the baseline MRI scan. After three months, MRI conversion to MS was observed in 80% and 62% of patients based on the appearance of ≥ 1 new T2 lesion and ≥ 1 new Gd-enhancing lesions, respectively. The presence of ≥ 1 new T2W lesion was observed in 90% and 82% of patients who had, at baseline, a Gd-positive MRI scan and dissemination in space based on the new McDonald’s criteria, respectively. The rate of MRI conversion remained almost stable in the last two MRI scans. Our study suggests that the majority of CIS patients with an abnormal baseline scan showed an MRI conversion to MS after three months. The model of six months as the optimal interval for repeating MRI exam is not supported by the present data.

Cerebral Microbleed

Rationale Cerebral microbleeds seen on brain magnetic resonance imaging are markers of small vessel disease, linked to cognitive dysfunction and increased ischemic and hemorrhagic stroke risk. Observational studies suggest that aspirin use may induce cerebral microbleeds, and associated overt intracranial hemorrhage, but this has not been definitively resolved. Aims ASPREE-NEURO will determine the effect of aspirin on cerebral microbleed development over three years in healthy adults aged 70 years and over, participating in the larger ‘ASPirin in Reducing Events in the Elderly (ASPREE)’ primary prevention study of aspirin. Sample size Five hundred and fifty-nine participants provide 75% power (two-sided p value of 0.05) to determine an average difference of 0.5 cerebral microbleed per person after three years. Methods and design A multi-center, randomized placebo-controlled trial of 100 mg daily aspirin in participants who have brain magnetic resonance imaging at study entry, one and three years after randomization and who undergo cognitive testing at the same time points. Study outcomes The primary outcome is the number of new cerebral microbleeds on magnetic resonance imaging after three years. Secondary outcomes are the number of new cerebral microbleeds after one year, change in volume of white matter hyperintensity, cognitive function, and stroke. Discussion ASPREE-NEURO will resolve whether aspirin affects the presence and number of cerebral microbleeds, their relationship with cognitive performance, and indicate whether consideration of cerebral microbleeds alters the risk-benefit profile of aspirin in primary prevention for older people.

Background: Spondylolysis and undiagnosed mechanical low back pain (UMLBP) are the main causes of low back pain (LBP) in adolescent athletes. No studies have evaluated the difference in clinical and radiographic factors between these 2 conditions. Furthermore, it remains unclear which adolescent athletes with LBP should undergo advanced imaging examination for spondylolysis. Purpose: To compare the clinical and radiographic factors of adolescent athletes with spondylolysis and UMLBP who did not have neurological symptoms or findings before magnetic resonance imaging (MRI) evaluation and to determine the predictors of spondylolysis findings on MRI. Study Design: Cohort study, Level of evidence, 3. Methods: The study population included 122 adolescent athletes aged 11 to 18 years who had LBP without neurological symptoms or findings and who underwent MRI. Of these participants, 75 were ultimately diagnosed with spondylolysis, and 47 were diagnosed with UMLBP. Clinical factors and the following radiographic parameters were compared between the 2 groups: spina bifida occulta, lumbar lordosis (LL) angle, and the ratio of the interfacet distance of L1 to that of L5 (L1:L5 ratio, %). A logistic regression analysis was performed to evaluate independent predictors of spondylolysis on MRI scans. Results: Significantly more athletes with spondylolysis were male (82.7% vs 48.9%; P < .001), had a greater LL angle (22.8° ± 8.1° vs 19.3° ± 8.5°; P = .02), and had a higher L1:L5 ratio (67.4% ± 6.3% vs 63.4% ± 6.6%; P = .001) versus athletes with UMLBP. A multivariate analysis revealed that male sex (odds ratio [OR], 4.66; P < .001) and an L1:L5 ratio of >65% (OR, 3.48; P = .003) were independent predictors of positive findings of spondylolysis on MRI scans. Conclusion: The study findings indicated that sex and the L1:L5 ratio are important indicators for whether to perform MRI as an advanced imaging examination for adolescent athletes with LBP who have no neurological symptoms and findings.

This is an update to the 2010 article published in Hospital Pharmacy on safety concerns involving transdermal patches and magnetic resonance imaging (MRI). Since publication of the original article, new brand and generic transdermal medications have become available and notable changes regarding the presence or absence of metallic content among existing transdermal formulations occurred. To update the tables within the article, Food and Drug Administration (FDA)-approved transdermal medications through October 2020 were researched in order to determine metallic content and procedures for reapplication after MRI, if applicable. Readers should consult the prescribing information or manufacturer for the most current information on use of transdermal medications in the MRI setting. Of note, manufacturers have not evaluated the use of transdermal products while patients undergo a MRI scan.

AbstractThe Kernohan-Woltman notch phenomenon is a paradoxical neurological manifestation consisting of a motor deficit ipsilateral to a primary brain injury. It has been observed in patients with brain tumors and with supratentorial hematomas. It is considered a false localizing neurological sign. Magnetic resonance imaging (MRI) scan has been the test of choice. The recognition of this phenomenon is important to prevent a surgical procedure on the opposite side of the lesion. The present case report describes a case of chronic subdural hematoma with a probable finding of the Kernohan-Woltman phenomenon, and it discusses its pathophysiology, imaging findings, treatment, and prognosis.
