PURPOSE Neuronal reorganization after blindness is of critical interest because it has implications for the rational prescription of artificial vision devices. The purpose of this study was to distinguish the microstructural differences between perinatally blind (PB), acquired blind (AB), and normally sighted controls (SCs) and relate these differences to(More)
PURPOSE This work intends to demonstrate a new method for quantifying concentration of sodium ((23) Na) of bi-exponential T2 relaxation in patients on MRI scanners at 3.0 Tesla. THEORY AND METHODS Two single-quantum (SQ) sodium images acquired at very-short and short echo times (TE = 0.5 and 5.0 ms) are subtracted to produce an image of the short-T2(More)
The benefits of multiplanar reconstructed images (MPR) of unenhanced axial head computed tomography (CT) data have not been established in trauma patients younger than 3 years old, a population in which a reliable history and physical examination may be most difficult. We retrospectively evaluated unenhanced head CTs in pediatric trauma patients to(More)
We evaluate novel magnetic resonance imaging (MRI) and positron emission tomography (PET) quantitative imaging biomarkers and associated multimodality, serial-time-point analysis methodologies, with the ultimate aim of providing clinically feasible, predictive measures for early assessment of response to cancer therapy. A focus of this work is method(More)
Sodium MRI (sMRI) has undergone a tremendous amount of technical development during the last two decades that makes it a suitable tool for the study of human pathology in the acute setting within the constraints of a clinical environment. The salient role of the sodium ion during impaired ATP production during the course of brain ischemia makes sMRI an(More)
OBJECTIVE To test for associations between abnormal respiratory ciliary motion (CM) and brain abnormalities in infants with congenital heart disease (CHD) STUDY DESIGN: We recruited 35 infants with CHD preoperatively and performed nasal tissue biopsy to assess respiratory CM by videomicroscopy. Cranial ultrasound scan and brain magnetic resonance imaging(More)
BACKGROUND Functional magnetic resonance imaging may help in elucidating the pathophysiology of post-traumatic anosmia. METHOD Using an fMRI olfactory stimulus paradigm, this study compared BOLD activation of the brain in a 21-year old male research subject with post-traumatic anosmia and a 19-year old male normal healthy control participant. OUTCOMES A(More)
