Editor’s Choice Aneurysm wall enhancement regions tend to have lower wall shear stress than nonenhanced regions of the same aneurysm. The association between flow conditions and aneurysm wall enhancement seems to depend on the location of the region on the
Editor’s Choice The authors’ evaluation of Viz LVO shows that the system has the potential for early identification of patients with stroke with large-vessel occlusions, hopefully improving future management and stroke care.
Editor’s Choice Machine learning-based feature selection can identify parameters with higher performance in outcome prediction.
Editor’s Choice Convolutional neural networks are able to learn discriminating features automatically, and these features provide added value for grading gliomas.
Fellows’ Journal Club Radiation-induced imaging changes are common following linear particle accelerator-based stereotactic radiosurgery for brain AVMs, appear to peak at 12 months, and are significantly associated with new neurologic findings.
Editor’s Choice CTP patterns helped to differentiate acute ischemic stroke from epileptic seizure in a “code stroke“ situation. The results indicate that a hyperperfusion pattern, especially if not restricted to a vascular territory, may suggest reconsideration of intravenous thrombolytic therapy.
Editor’s Choice Patients who received IV iodinated contrast in proximity (<8 hours) to CTA/CTP as part of a separate imaging study had a much higher likelihood of core infarct underestimation with RAPID software compared with contrast-naive patients. Over-reliance on RAPID
Fellows’ Journal Club The authors describe 10 patients (16 years of age or older) with acute necrotizing encephalopathy. In their study, bilateral thalamic involvement with the trilaminar pattern of diffusion restriction on MR imaging was the predominant finding seen in
Editor’s Choice Neurite orientation dispersion and density imaging (NODDI) assesses microstructural features of neurites contributing to diffusion imaging signals. Twenty-one subjects with MS underwent serial enhanced MRIs including NODDI, the key metrics of which are the neurite density and orientation
Fellows’ Journal Club Nineteen patients with spontaneous intracranial hypotension with a proved spinal CSF leak were investigated between July 2014 and 2017. Brain MR imaging-based volumetry at baseline and after surgery was performed with FreeSurfer. In addition, the spontaneous intracranial
