Effects of MRI Protocol Parameters, Preload Injection Dose, Fractionation Strategies, and Leakage Correction Algorithms on the Fidelity of Dynamic-Susceptibility Contrast MRI Estimates of Relative Cerebral Blood Volume in Gliomas

Jeffrey Ross March 26, 2017March 24, 2017 Brain, Fellows' Journal Club

Fellows’ Journal Club The authors used DSC-MR imaging simulations to examine the influence of various acquisition parameters and leakage-correction strategies on the faithful estimation of CBV. Optimal strategies were determined by protocol with the lowest mean error. They conclude that

Transverse Sinus Stenosis Is the Most Sensitive MR Imaging Correlate of Idiopathic Intracranial Hypertension

Jeffrey Ross March 19, 2017March 20, 2017 Fellows' Journal Club

Fellows’ Journal Club MR imaging and MRV images from 63 patients with idiopathic intracranial hypertension and 96 controls were reviewed by using 3 independent procedures. MRV images were graded for the presence and degree of stenosis of the transverse sinus.

Ascending and Descending Thoracic Vertebral Arteries

Jeffrey Ross March 5, 2017March 6, 2017 Extracranial Vascular, Fellows' Journal Club

Fellows’ Journal Club The authors report the angiographic anatomy and clinical significance of 9 cases of descending and 2 cases of ascending thoracic vertebral arteries. Located within the upper costotransverse spaces, ascending and descending thoracic vertebral arteries may have important

Endovascular Stroke Treatment of Nonagenarians

Jeffrey Ross February 26, 2017February 24, 2017 Fellows' Journal Club, Interventional

Fellows’ Journal Club The purpose of this study was the evaluation of procedural and outcome data of patients 90 years of age or older undergoing endovascular stroke treatment. The authors retrospectively analyzed prospectively collected data of 29 patients (mean age

Synthetic MRI in the Detection of Multiple Sclerosis Plaques

Jeffrey Ross February 19, 2017February 17, 2017 Brain, Fellows' Journal Club

Fellows’ Journal Club In this retrospective study, synthetic T2-weighted, FLAIR, double inversion recovery, and phase-sensitive inversion recovery images were produced in 12 patients with MS after quantification of T1 and T2 values and proton density. Double inversion recovery images were

White Matter Injury and General Movements in High-Risk Preterm Infants

Jeffrey Ross February 5, 2017February 3, 2017 Fellows' Journal Club, Pediatrics

Fellows’ Journal Club Cerebral palsy has been predicted by analysis of spontaneous movements in the infant termed “General Movement Assessment.” The authors evaluated the utility of General Movement Assessment in predicting adverse cognitive, language, and motor outcomes in very preterm

Endovascular Therapy of M2 Occlusion in IMS III: Role of M2 Segment Definition and Location on Clinical and Revascularization Outcomes

Jeffrey Ross February 3, 2017February 3, 2017 Fellows' Journal Club, Interventional

Fellows’ Journal Club The authors reviewed the impact of revascularization on clinical outcomes in 83 patients with M2 occlusions in the Interventional Management of Stroke III trial according to specific M1–M2 segment anatomic features. AnmRS 0–2 outcome was associated with

Fellows’ Journal Club Recap: Quantitative MRI for automated CSF measurements in hydrocephalus evaluation

Brent Weinberg January 30, 2017January 28, 2017 Fellows' Journal Club

Please check out the accompanying podcast of this blog post (discussion of this article begins at 15:07) Current evaluation of idiopathic normal pressure hydrocephalus (NPH) depends predominantly on clinical examination, although there are some imaging features, including enlarged lateral ventricles,

Intracranial Arteriovenous Shunting: Detection with Arterial Spin-Labeling and Susceptibility-Weighted Imaging Combined

Jeffrey Ross January 22, 2017January 20, 2017 Brain, Fellows' Journal Club

Fellows’ Journal Club Ninety-two consecutive patients with a known (n = 24) or suspected arteriovenous shunting (n = 68) underwent DSA and brain MR imaging, including arterial spin-labeling/SWI and conventional angiographic MR imaging. DSA showed arteriovenous shunting in 63 of

CT and MR Imaging in the Diagnosis of Scleritis

Jeffrey Ross January 1, 2017December 20, 2016 Fellows' Journal Club, Head and Neck

Fellows’ Journal Club Scleritis is a rare vision-threatening condition that can occur isolated or in association with other orbital abnormalities and whose etiology is typically inflammatory/noninfectious, either idiopathic or in the context of systemic disease. The authors analyzed 11 cases
