Abstract
BACKGROUND AND PURPOSE The use of MR imaging in emergency settings has been limited by availability, long scan times, and sensitivity to motion. This study assessed the diagnostic performance of an ultrafast brain MR imaging protocol for evaluation of acute intracranial pathology in the emergency department and inpatient settings. MATERIALS AND METHODS Sixty-six adult patients who underwent brain MR imaging in the emergency department and inpatient settings were included in the study. All patients underwent both the reference and the ultrafast brain MR protocols. Both brain MR imaging protocols consisted of T1-weighted, T2/T2*-weighted, FLAIR, and DWI sequences. The ultrafast MR images were reconstructed by using a machine-learning assisted framework. All images were reviewed by 2 blinded neuroradiologists. RESULTS The average acquisition time was 2.1 minutes for the ultrafast brain MR protocol and 10 minutes for the reference brain MR protocol. There was 98.5% agreement on the main clinical diagnosis between the 2 protocols. In head-to-head comparison, the reference protocol was preferred in terms of image noise and geometric distortion (P < .05 for both). The ultrafast ms-EPI protocol was preferred over the reference protocol in terms of reduced motion artifacts (P < .01). Overall diagnostic quality was not significantly different between the 2 protocols (P > .05). CONCLUSIONS The ultrafast brain MR imaging protocol provides high accuracy for evaluating acute pathology while only requiring a fraction of the scan time. Although there was greater image noise and geometric distortion on the ultrafast brain MR protocol images, there was significant reduction in motion artifacts with similar overall diagnostic quality between the 2 protocols.

Abstract
BACKGROUND Emergency hospital admissions are common in multiple sclerosis (MS), and can highlight unmet medical needs. OBJECTIVES To evaluate burden, predictors and outcomes of MS emergency admissions. METHODS This is a population-based study, conducted in the Campania Region (South Italy) from 2015 to 2019, using hospital discharge records, drug prescriptions and outpatients. The risk of emergency hospital admissions and the likelihood of worse outcomes were evaluated using the Cox regression and multinomial logistic regression models, respectively, in relation to age, sex, disease-modifying treatments (DMTs), comorbidities and adherence. RESULTS We recorded 1225 emergency admissions for 1001 patients (out of 5765 prevalent MS patients), overall costing 4,143,764.67 EUR. The risk of emergency admissions increased with age (hazard ratio (HR) = 1.02; 95% confidence interval (CI) = 1.01, 1.03; p < 0.01) and comorbidities (HR = 1.62; p < 0.01), and decreased in patients using DMTs (interferon beta/peg-interferon beta/glatiramer acetate HR = 0.19; p < 0.01; teriflunomide/dimethyl-fumarate/fingolimod HR = 0.18; p < 0.01, and alemtuzumab/cladribine/natalizumab/ocrelizumab HR = 0.21; p < 0.01), and with higher adherence (HR = 0.18; 95% CI = 0.13, 0.26; p < 0.01). Following emergency admission, older age was associated with probability of death (n = 63) (odds ratio (OR) = 1.06; p < 0.01) and discharge to long-term facility (n = 65) (OR = 1.03; p = 0.01). CONCLUSION With 17% people with MS requiring emergency medical care over 5 years, improved management of DMTs and comorbidities could potentially reduce their medical, social and financial burden.

Major Radiologic and Clinical Outcomes of Total Spine MRI Performed in the Emergency Department at a Major Academic Medical Center. AJNR Am J Neuroradiol 2020; 41:1120-1125. [PMID: 32439645 DOI: 10.3174/ajnr.a6578] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Accepted: 03/24/2020] [Indexed: 11/07/2022]
Abstract
BACKGROUND AND PURPOSE Total spine MRIs are requested by the emergency department when focused imaging can not be ordered on the basis of history or clinical findings. However, their efficacy is not known. We assessed the following: 1) major radiologic and clinical outcomes of total spine MR imaging performed by the emergency department, and 2) whether the presence of a high-risk clinical profile and/or neurologic findings impacts the clinical outcomes. MATERIALS AND METHODS Total spine MRIs requested by the emergency department during a 28-month period were evaluated for major radiologic (cord compression, cauda equina compression, and other significant findings) and major clinical outcomes (hospital admission during the visit followed by an operation, radiation therapy, or intravenous antibiotics or steroids). Associations between a high-risk clinical profile (cancer, infection, coagulopathy) and/or the presence of neurologic findings and outcomes were assessed. RESULTS After we excluded trauma or nondiagnostic studies, 321/2047 (15.7%) MRIs ordered during study period were total spine MR imaging; 117/321 (36.4%) had major radiologic and 60/321 (18.6%) had major clinical outcomes (34/60 in <24 hours); and 58/117(49.6%) with major radiologic outcome were treated compared with 2/205 (1.0%) without (OR = 99, P < .001). The presence of both a high-risk clinical profile and neurologic findings concurrently in a patient (142/321) increased the likelihood of major clinical outcomes during the same visit (OR = 3.1, P < .001) and in <24-hours (OR = 2.6, P = .01) compared with those with either a high-risk clinical profile or neurologic findings alone (179/321). CONCLUSIONS Total spine MR imaging ordered by our emergency department has a high radiologic and significant clinical yield. When a high-risk clinical profile and neurologic findings are both present in a patient, they should be prioritized for emergent total spine MR imaging, given the increased likelihood of clinical impact.
