Please check out the accompanying podcast of this blog post (discussion of this article begins at 8:30) Glioblastoma is a heterogeneous group of cancers, genetically, molecularly and characteristically on imaging studies. Prior studies have supported the relationship between tumor location
Fellows’ Journal Club Seven giant intracranial aneurysms were evaluated, and 2 aneurysms were available for histopathologic examination. Aneurysm walls were depicted as hypointense in TOF-MRA and SWI sequences with excellent contrast ratios to adjacent brain parenchyma. A triple-layered microstructure of
Editor’s Choice Preoperative T1 anatomic MR images of 384 patients with glioblastomas were evaluated by an automated computational image-analysis pipeline to determine the anatomic locations of tumor in each patient. Voxel-based differences in tumor location between good and poor survival

Editor’s Choice Editor’s Comment Patients with malignant brain tumors involving the central region underwent a hybrid O-(2-[18F]fluoroethyl)-L-tyrosine–PET-MR imaging and motor mapping by neuronavigated transcranial magnetic stimulation. The spatial relationship between functional tissue and lesion volumes as depicted by structural and
Borden NM, Forseen SE, Stefan C. Imaging Anatomy of the Human Brain: A Comprehensive Atlas Including Adjacent Structures. DemosMEDICAL; 2015; 464 pp; 1000 ill; $185.00 The bedrock of neuroradiology—in fact, of all of radiology—is a strong understanding of the pertinent anatomy. When combined
Fellows’ Journal Club Editor’s Comment In this study of 793 patients with 906 aneurysms, 20 (2.5%) had intraparenchymal hemorrhage. Nine patients with intraparenchymal hemorrhage (45.0%) died, 10 (50.0%) had major neurologic morbidity, and 1 (5.0%) had minor neurologic morbidity. Variables
Fellows’ Journal Club Editor’s Comment These authors retrospectively evaluated 12 patients with natalizumab–progressive multifocal leukoencephalopathy (PML), 5 with PML from other causes, and 55 patients with MS without progressive PML for comparison. They observed T2* or SWI signal abnormalities at
Editor’s Choice Editor’s Comment Serial T1WI and 1H-MR spectroscopy data were acquired in 15 healthy individuals at normohydration, at 12 hours of dehydration, and during 1 hour of oral rehydration. Osmotic challenges were monitored by serum measures, including osmolality and
Fellows’ Journal Club Editor’s Comment Patients with suspected idiopathic normal pressure hydrocephalus (NPH) on the basis of the ventriculomegaly and a triad of symptoms underwent the CSF tap test. CSF volumes were extracted from a T2-weighted 3D spin-echo SPACE sequence
