Fellows’ Journal Club One hundred thirty-one patients with histologically proved solid sinonasal lesions (56 benign and 75 malignant) who underwent conventional DWI and intravoxel incoherent motion were evaluated. The diffusion coefficient (D), pseudodiffusion coefficient (D*), and perfusion fraction (f) values
Editor’s Choice This is a retrospective analysis of 59 patients who received only gadobutrol and 60 patients who received only linear gadolinium-based contrast agents. Linear gadolinium-based contrast agents included gadoversetamide, gadobenatedimeglumine, and gadodiamide. T1 signal intensity in the globus pallidus,
Editor’s Choice Nine patients with suspected elevated intracranial pressure and 9 healthy control patients were included in this prospective study. Control patients underwent DENSE MR imaging through the midsagittal brain while patients underwent DENSE MR imaging followed immediately by lumbar
Editor’s Choice The authors evaluated 60 patients with dynamic contrast-enhanced MR imaging before treatment. Median, mean intracellular water molecule lifetime, and volume transfer constant values from metastatic nodes were computed from each patient. Kaplan-Meier analyses were performed to associate mean
Fellows’ Journal Club The authors review the relevant cardiac implantable electronic devices encountered in practice today, the background physics/technical factors related to scanning these devices, the multidisciplinary screening protocol used at their institution for scanning patients with implantable cardiac devices,
Fellows’ Journal Club The authors assessed regional CBF in patients with idiopathic normal pressure hydrocephalus compared with healthy controls using the noninvasive quantitative arterial spin-labeling MR imaging technique. Twenty-one consecutive patients with NPH and 21 age- and sex-matched randomly selected
Fellows’ Journal Club The authors sought to determine whether the L5 vertebra could be accurately localized by using nerve morphology on MR imaging. A sample of 108 cases with full spine MR imaging were numbered from the C2 vertebral body
Editor’s Choice Fifty-eight patients with pathologically confirmed gliomas underwent preoperative 3D pseudocontinuous arterial spin-labeling and ROC curves were generated for parameters to distinguish high-grade from low-grade gliomas. Both maximum CBF and maximum relative CBF were significantly higher in high-grade than
Editor’s Choice Fifty-three intracranial arterial specimens with atherosclerotic plaques from 20 cadavers were imaged by 3T MR with T1, T2, and proton-density–weighted FSE and STIR sequences. The signal characteristics and areas of fibrous cap, lipid core, calcification, fibrous tissue, and
Editor’s Choice A group of 133 patients with primary glioblastoma who underwent postcontrast T1-weighted imaging (acquired before treatment) and whose data were filed with the survival times were selected from the Cancer Genome Atlas. On the basis of overall survival,
