Assessment of the Frequency-Domain Multi-Distance Method to Evaluate the Brain Optical Properties: Monte Carlo Simulations from Neonate to Adult
Dehaes, Mathieu; Grant, P. Ellen; Sliva, Danielle D.; Roche-Labarbe, Nadege; Pienaar, Rudolph; Boas, David A.; Franceschini, Maria A.; Selb, Juliette J (Optical Society of America, 2011)The near infrared spectroscopy (NIRS) frequency-domain multi-distance (FD-MD) method allows for the estimation of optical properties in biological tissue using the phase and intensity of radiofrequency modulated light at ... -
Failure to Identify the Left Arcuate Fasciculus at Diffusion Tractography Is a Specific Marker of Language Dysfunction in Pediatric Patients with Polymicrogyria
Paldino, Michael J.; Hedges, Kara; Gaab, Nadine; Galaburda, Albert M.; Grant, P. Ellen (Hindawi Publishing Corporation, 2015)Background:. Polymicrogyric cortex demonstrates interindividual variation with regard to both extent of dyslamination and functional capacity. Given the relationship between laminar structure and white matter fibers, we ... -
Maximum Entropy Estimation of Glutamate and Glutamine in MR Spectroscopic Imaging
Rathi, Yogesh; Ning, Lipeng; Michailovich, Oleg; Liao, Huijun; Gagoski, Borjan; Grant, P. Ellen; Shenton, Martha Elizabeth; Stern, Robert Stuart; Westin, Carl-Fredrik; Lin, Alexander Peter (Springer Science + Business Media, 2014)Magnetic resonance spectroscopic imaging (MRSI) is often used to estimate the concentration of several brain metabolites. Abnormalities in these concentrations can indicate specific pathology, which can be quite useful in ... -
Pediatric neuroimaging in early childhood and infancy: challenges and practical guidelines
Raschle, Nora; Zuk, Jennifer Margaret; Ortiz-Mantilla, Silvia; Sliva, Danielle D.; Franceschi, Angela; Grant, P. Ellen; Benasich, April A.; Gaab, Nadine (Wiley-Blackwell, 2012)Structural and functional magnetic resonance imaging (fMRI) has been used increasingly to investigate typical and atypical brain development. However, in contrast to studies in school-aged children and adults, MRI research ... -
Reduced cerebral blood flow and oxygen metabolism in extremely preterm neonates with low-grade germinal matrix- intraventricular hemorrhage
Lin, Pei-Yi; Hagan, Katherine; Fenoglio, Angela; Grant, P. Ellen; Franceschini, Maria Angela (Nature Publishing Group, 2016)Low-grade germinal matrix-intraventricular hemorrhage (GM-IVH) is the most common complication in extremely premature neonates. The occurrence of GM-IVH is highly associated with hemodynamic instability in the premature ... -
Reliable Identification of Deep Sulcal Pits: The Effects of Scan Session, Scanner, and Surface Extraction Tool
Im, Kiho; Lee, Jong-Min; Jeon, Seun; Kim, Jong-Heon; Seo, Sang Won; Na, Duk L.; Grant, P. Ellen (Public Library of Science, 2013)Sulcal pit analysis has been providing novel insights into brain function and development. The purpose of this study was to evaluate the reliability of sulcal pit extraction with respect to the effects of scan session, ... -
Transient and Persistent Pain Induced Connectivity Alterations in Pediatric Complex Regional Pain Syndrome
Linnman, Clas; Becerra, Lino; Lebel, Alyssa; Berde, Charles Benjamin; Grant, P. Ellen; Borsook, David (Public Library of Science, 2013)Evaluation of pain-induced changes in functional connectivity was performed in pediatric complex regional pain syndrome (CRPS) patients. High field functional magnetic resonance imaging was done in the symptomatic painful ... -
Two uniqueTUBB3mutations cause both CFEOM3 and malformations of cortical development
Whitman, Mary Catherine; Andrews, Caroline; Chan, Wai-Man; Tischfield, Max A.; Stasheff, Steven F.; Brancati, Francesco; Ortiz-Gonzalez, Xilma; Nuovo, Sara; Garaci, Francesco; MacKinnon, Sarah E.; Hunter, David; Grant, P. Ellen; Engle, Elizabeth Carson (Wiley, 2015)One set of missense mutations in the neuron specific beta tubulin isotype 3 (TUBB3) has been reported to cause malformations of cortical development (MCD), while a second set has been reported to cause isolated or syndromic ...
