Fellows’ Journal Club The authors analyzed 1.5T MRI examinations of 100 consecutive patients treated with radiation therapy with or without additional surgery for head and neck squamous cell carcinoma. MRI examinations included morphologic sequences and DWI. Histology and follow-up served
Fellows’ Journal Club The authors conducted a retrospective review of 58 patients with 62 MR imaging studies performed within 72 hours following endovascular treatment of intracranial aneurysms. Patient demographics, aneurysm location, and vascular territory distribution of cortical and sulcal hyperintensity
Fellows’ Journal Club Ninety-three patients with World Health Organization grade II gliomas with known IDH-mutation and 1p/19q-codeletion status (18 IDH1 wild-type, 45 IDH1-mutant and no 1p/19q codeletion, 30 IDH-mutant and 1p/19q codeleted tumors) underwent DTI. ROIs were drawn on every section of the T2-weighted images
Fellows’ Journal Club DTI and dynamic contrast-enhanced MR imaging using T1-mapping with flip angles of 2°, 5°, 10°, and 15°, followed by a 0.1-mmol/kg body weight gadolinium-based bolus was performed on 41 patients in addition to standard MR imaging. Permeability
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
Fellows’ Journal Club The authors evaluated 1073 patients with anterior circulation stroke undergoing mechanical thrombectomy between 2010 and 2016. Patients with wake-up stroke and daytime-unwitnessed stroke were compared with controls receiving mechanical thrombectomy as the standard of care. There was
Fellows’ Journal Club Twenty patients with deep lumbosacral spinal dural arteriovenous fistulas were included in this series. Cord T2 hyperintensity and contrast enhancement were present in most cases. The filum vein and/or lumbar veins were dilated in 95% of patients.
Fellows’ Journal Club A retrospective analysis of a prospectively collected lymphatic malformation data base was performed that included 16 patients (5 males, 11 females; mean age, 15 years; range, 1=47 years). Patients with at least 1 microcystic lymphatic malformation component
Fellows’ Journal Club From January 2011 through January 2016, among 2979 patients with acute ischemic stroke, the authors identified 27 patients who underwent permanent stent placement (13 patients with the Solitaire FR and 14 patients with other self-expanding stents). The
Fellows’ Journal Club The authors performed a retrospective analysis of all ruptured and unruptured aneurysms treated with a WEB device between August 2014 and February 2017. Primary outcome measures included the feasibility of implantation and the angiographic outcome. Secondary outcome
