Magnetic resonance imaging (MRI) allows for high resolution imaging of the central nervous system. We have tested the feasibility of using MRI in conjunction with quantitative image analysis to perform volumetric measurements of the brain in the developing human fetus in utero. The database comprises MR images of a total of 56 fetuses (gestational age 25-41(More)
PURPOSE To determine the change over time of the apparent diffusion coefficient (ADC) and relative anisotropy of cerebral water in a cohort of premature newborns serially studied near birth and again near term. MATERIALS AND METHODS Newborns were classified as normal (N = 11), minimal white matter injury (N = 7), or moderate white matter injury (N = 5).(More)
The development of imaging methodologies for detecting blood-brain-barrier (BBB) disruption may help predict stroke patient's propensity to develop hemorrhagic complications following reperfusion. We have developed a delayed contrast extravasation MRI-based methodology enabling real-time depiction of subtle BBB abnormalities in humans with high sensitivity(More)
Parry-Romberg is a rare syndrome of unknown origin, characterized by hemiatrophy of the face including subcutaneous tissue, skeletal muscle, and bones, along with various ocular and central nervous system abnormalities. Some investigators consider that injury to the sympathetic fibers of the trigeminal nerve is a cause for evolution of this syndrome.(More)
The aim of the study was to examine the relationship between EEG abnormalities and the pattern of MRI changes in familial Creutzfeldt-Jakob Disease (fCJD) patients with E200K mutation. As part of a controlled, prospective study, 13 E200K fCJD patients underwent comprehensive evaluations, with EEG and an extensive MRI protocol that included one of the most(More)
Pruritus, a common feature of animal prion diseases such as scrapie, is rarely reported in humans with Creutzfeldt-Jakob disease (CJD), and its anatomical background is not well defined. The present study was undertaken to carry out a methodical prospective search for the prevalence of pruritus in CJD patients and investigate its anatomical substrate by(More)
