Fellows’ Journal Club The authors explored the effect of multimodal imaging (CT perfusion and/or CT angiography) versus noncontrast CT alone on time to treatment and outcomes in the IMS III trial. Of 656 subjects enrolled in the trial, 90 (13.7%)
Editor’s Choice The authors’ hypothesis is that incorporating bidirectional contrast agent transport into the DSC MR imaging signal model will improve rCBV estimates in brain tumors. A unidirectional contrast agent extravasation model (Boxerman-Weisskoff) was compared with a bidirectional contrast agent
Fellows’ Journal Club The authors evaluated the clinical records and neuroimaging of patients with spontaneous intracranial hypotension from September 2005 to August 2014. Patients with classic spontaneous intracranial hypotension (n = 33) were compared with those with intracranial hypotension with
Editor’s Choice Twenty-one patients with MS and 21 patients with neuromyelitis optica underwent 7T high-resolution 2D-gradient-echo-T2* and 3D-susceptibility-weighted imaging. An in-house-developed algorithm was used to reconstruct quantitative susceptibility mapping from SWI. Of the patients with MS, 19 (90.5%) demonstrated at
Editor’s Choice The authors evaluated fiber bundle orientations from DTI and diffusional kurtosis compared with diffusion spectrum imaging as a criterion standard to assess the performance of each technique. DTI, diffusional kurtosis imaging, and diffusion spectrum imaging datasets were acquired
Editor’s Choice SyMRI is a quantitative synthetic MR imaging method where a single saturation recovery TSE sequence is used to estimate the proton density, longitudinal relaxation rate, and transverse relaxation rate and allows for a free range of synthetic weightings.
Editor’s Choice Twenty-eight patients with newly presenting glioblastoma multiforme underwent preoperative conventional imaging and T1 dynamic contrast-enhanced MRI. Parametric maps of the initial area under the contrast agent concentration curve, contrast transfer coefficient, estimate of volume of the extravascular extracellular
Fellows’ Journal Club Eight symptomatic patients with Chiari I malformation and 6 healthy participants were studied by using MR pencil beam imaging with a temporal resolution of 50 ms. Patients and healthy participants were scanned in real-time during resting, coughing,
Editor’s Choice The authors evaluated 24 patients with Parkinson disease and 24 age- and sex-matched healthy controls who underwent 3T MR imaging with a 3D multiecho gradient-echo sequence. On reconstructed quantitative susceptibility maps they measured the susceptibility values in the
Editor’s Choice T1-weighted enhanced brain imaging was performed in 24 pediatric patients comparing the reference Cartesian TSE sequence (2 minutes 30 seconds) with a spiral spin-echo sequence (1 minutes 18 seconds) with similar spatial resolution and coverage. In 23/24 cases,
