Diagnosing multiple sclerosis (MS) is challenging, in part because imaging findings in MS partially overlap with MS mimics such as vascular disease, migraine, and neuromyelitis optica spectrum disorder (NMOSD). The central vein sign has been shown to be a highly sensitive and specific biomarker for MS based on results...
Newborn babies have variations in white matter development, but it is unknown whether these variations are associated with changes in later neurodevelopment. In this prospective cohort study, investigators performed MRI examinations for 38 full-term infants at 2 weeks of age and then followed up at 2 years with the...
For patients with rectal cancer, the strongest predictor of local recurrence is the circumferential resection margin (CRM) after surgery, with negative CRMs being the goal. Current guidelines recommend preoperative chemoradiotherapy (CRT) before surgery, as this has been shown to decrease the rate of local recurrence. CRT, however, is associated...
Safety and Feasibility of Using Magnetic Resonance Imaging Criteria to Identify Patients With “Good Prognosis” Rectal Cancer Eligible for Primary Surgery: The Phase 2 Nonrandomized QuickSilver Clinical Trial For patients with rectal cancer, the strongest predictor of local recurrence is the circumferential resection margin (CRM) after surgery, with negative CRMs...
1. This systematic review and meta-analysis demonstrated the high diagnostic performance of magnetic resonance (MR) enterography in the diagnosis of active inflammation in pediatric inflammatory bowel disease (IBD). 2. There was substantial heterogeneity, some of which was unexplained, in the original studies which limits the reliability of this study. Evidence Rating...
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. In a retrospective review of 100 patient recall requests for diagnostic imaging, over 90% of all recalls were for magnetic resonance imaging (MRI) requests. 2. Most recalls were due to an incomplete examination, but other causes included inadequate coverage of the area of interest, protocoling errors, poor image quality...
1. In young patients with right lower quadrant (RLQ) pain who present to the emergency department, abdominal magnetic resonance imaging (MRI) performed without intravenous or oral contrast enhancement detected acute appendicitis with a high sensitivity and specificity based upon reference surgical results and clinical follow-up data. 2. In patients who...
  1. In a retrospective review of over 6000 patients with breast cancer, pre-operative breast magnetic resonance imaging (MRI) does not significant improve the detection of clinically significant contralateral breast cancers (CBC). Evidence Rating Level: 3 (Average) Study Rundown: In breast cancer patients, pre-operative MRI are commonly used for screening of CBCs....
1. Among patients with drug-resistant temporal lobe epilepsy not associated with a brain lesion, focally elevated levels of glutamate were detected to correctly lateralize the epileptogenic focus using glutamate chemical exchange saturation transfer (GluCEST) imaging. 2. No significant differences in hippocampal volumes were detected between the hemispheres of affected patients,...
