MDCT of Adrenal Masses: Can Dual-Phase Enhancement Patterns Be Used to Differentiate Adenoma and Pheochromocytoma?Benjamin G. Northcutt1, Siva P. Raman1, Christopher Long1, Alexander R. Oshmyansky1, Stanley S. Siegelman1, Elliot K. Fishman1 Pamela T. Johnson1Audio Available | Share
The purpose of this article is to assess the role diffusion-weighted MRI in characterizing adrenal masses.A retrospective review database from August 2007 July 2009 was performed. examinations 48 patients, with 49 lesions, were reviewed independently and blindly by two experienced abdominal radiologists who measured signal intensities on in-phase opposed-phase T1-weighted imaging apparent diffusion coefficient (ADC). ADC measurements quantitative parameters chemical shift (signal intensity...
To study the quality and usability of magnetic resonance imaging (MRI) obtained with a cochlear implant magnet in situ.Retrospective chart review.Tertiary care center.All patients who underwent brain MRI situ from 2007 to 2016.None.Grade view ipsilateral internal auditory canal (IAC) cerebellopontine angle (CPA).Inclusion criteria were met by 765 image sequences 57 scans. For IAC, significant predictors grade 1 (normal) included: absence fat saturation algorithm (p = 0.001), nonaxial plane...
Purpose The aim of the study was to compare multidetector CT venous enhancement level and washout characteristics adrenal adenoma pheochromocytoma, with goal defining a predictive pheochromocytoma. Methods Retrospective review medical records between 2002 2012 performed identify masses measuring less than 4 cm. Inclusion criteria for adenomas phase contrast-enhanced computed tomography (CT), confirmatory (precontrast ± washout), 1 2 years stability, absence clinical indicators All...
Thin-section MR imaging through the posterior fossa is frequently used for trigeminal neuralgia. Typical heavily T2-weighted methods yield high anatomic detail and contrast between CSF neurovascular structures, but poor vessels nerves. We hypothesized that addition of gadolinium-based material to 3D-constructive interference in steady-state would improve characterization compression.Retrospective review high-resolution MRIs was performed patients without prior microvascular decompression....
<h3>BACKGROUND AND PURPOSE:</h3> Patients with trigeminal neuralgia often undergo rhizotomy via radiofrequency thermocoagulation or glycerol injection for treatment of symptoms. To date, radiologic changes in patients post-rhizotomy have not been described, to our knowledge. The aim this study was evaluate after characterize on 3D high-resolution MR imaging. <h3>MATERIALS METHODS:</h3> A retrospective review protocol studies performed 26 compared 54 treatment-naïve subjects neuralgia....
INTRODUCTION: MRI is performed in the assessment of patients with trigeminal neuralgia (TGN). However, there poor contrast between vessels and nerves, because both are low intensity on heavily T2-weighted images. METHODS: A retrospective review was high-resolution 3D studies from 2011 to 2014. Eighty-one TGN 15 controls were independently reviewed by 2 neuroradiologists a blinded fashion. The cisternal segment nerve root assessed bilaterally for metrics neurovascular conflict, including...
INTRODUCTION: Patients with trigeminal neuralgia often undergo glycerol or radiofrequency-thermocoagulation rhizotomy of the nerve for treatment symptoms. To date, radiological changes in patients postrhizotomy have not been described. The aim this study was to evaluate after characterize on 3D high-resolution MRI. METHODS: A retrospective review protocol studies performed 26 compared 54 treatment-naive subjects. Examinations were reviewed independently by 2 neuroradiologists blinded side...
