Fellows’ Journal Club This study aimed to evaluate morphologic patterns and the delineation of deeply seated collateral networks using ultra-high-field MRA in comparison with conventional DSA in 15 patients. Sequences acquired at 7T were TOF-MRA with 0.22 X 0.22 X
Editor’s Choice MR imaging data and molecular information were retrospectively obtained from The Cancer Imaging Archives for 259 patients with either low- or high-grade gliomas. A convolutional neural network was trained to classify IDH1 mutation status, 1p/19q codeletion, and MGMT promotor methylation status. Classification
Editor’s Choice The authors compared WM lesions in a group of patients with multiple sclerosis and in a second group of positive controls with white matter lesions who did not have a diagnosis of MS. The presence of a rim
Editor’s Choice DSC-MR imaging data were collected after a preload and during a bolus injection of gadolinium contrast agent using a gradient recalled-echo-EPI sequence. Forty-nine low-grade and high-grade glioma datasets were uploaded to The Cancer Imaging Archive. Datasets included a
Editor’s Choice Intracranial dolichoectasia of the distal ICA was identified in 20 patients from 2005–2016 through a review of diagnostic cerebral angiography results. Images were reviewed to determine the vascular morphologic dispositions around the distal ICA, including dysplasia, mural calcification,
Fellows’ Journal Club The authors enrolled 53 patients with anti-N-methyl-D-aspartate receptor encephalitis and performed 2-year follow-up. Brain MRIs were acquired for all patients at the onset phase. The brain MR imaging manifestations were classified into 4 types—type 1: normal MR
Editor’s Choice Ten unruptured aneurysms in 9 patients were studied using a high-resolution 3D gradient-echo sequence with cardiac gating. Semiautomatic segmentation was used to measure aneurysm volume per cardiac phase. Aneurysm pulsation was defined as the relative increase in volume
Fellows’ Journal Club The authors conducted a retrospective review of 58 patients with 62 MR imaging studies performed within 72 hours following endovascular treatment of intracranial aneurysms. Patient demographics, aneurysm location, and vascular territory distribution of cortical and sulcal hyperintensity
Editor’s Choice Twenty-five patients with relapsing-remitting MS and 20 healthy volunteers were enrolled in a prospective study with a protocol including anatomic imaging, standard magnetization transfer, and inhomogeneous magnetization transfer imaging. Magnetization transfer and inhomogeneous magnetization transfer ratios measured in
