Editor’s Choice Editor’s Comment The authors retrospectively reviewed patients treated between 2007–2010 and identified 14 patients with cerebral metastasis who had clinical or radiographic progression following stereotactic radiosurgery and were imaged with arterial spin-labeling (ASL), FDG-PET, and thallium SPECT before
Editor’s Choice Editor’s Comment At 7T, 2D multiecho spin-echo T2WI and 3D gradient-echo T2*WI were acquired from 27 formalin-fixed coronal hemispheric brain sections of 15 patients and 4 healthy controls. Proteolipid-stained tissue sections were matched to the corresponding MR images,
Editor’s Choice Editor’s Comment Nigrosomes are calbindin-poor zones within the substantia nigra pars compacta, and are the primary subregion where dopaminergic cells are lost in Parkinson disease. High-resolution 3D multiecho imaging was performed at 3T in 13 healthy subjects and

Fellows’ Journal Club Editor’s Comments The authors evaluated the effect of jugular compression on brain tissue stiffness and CSF flow by evaluating 9 volunteers, with and without jugular compression, with MR elastography and phase-contrast CSF flow imaging. The shear moduli
Fellows’ Journal Club Editor’s Comments This is a retrospective study that included 54 patients with a cystic pituitary adenoma and 28 patients with a Rathke cleft cyst who underwent MR imaging followed by surgery. Regression analysis showed that cystic pituitary
Fellows’ Journal Club Editor’s Comments This is a retrospective review of the medical records of 706 consecutive patients who were treated with irradiation for primary brain tumors at The Johns Hopkins Medical Institutions between June 1995–January 2010. The authors found
Editor’s Choice Editor’s Comment Relative CBV estimates were calculated from dynamic susceptibility contrast MR imaging in double-baseline examinations of 33 patients with treatment-naïve and pathologically proved glioblastoma multiforme. Normalized and standardized relative CBV were calculated by using 6 common postprocessing
Fellows’ Journal Club Editor’s Comment The authors performed a crossover, intraindividual comparison of 0.1-mmol/kg gadobenate with 0.1-mmol/kg gadoterate (Arm 1) and 0.05-mmol/kg gadobenate with 0.1-mmol/kg gadoterate (Arm 2). In Arm 1, a significant superiority of 0.1-mmol/kg gadobenate was demonstrated by
