Age-related changes in intracranial compartment volumes in normal adults assessed by magnetic resonance imaging.
Magnetic resonance (MR) image-based computerized segmentation was used to measure various intracranial compartments in 49 normal volunteers ranging in age from 24 to 80 years to determine age-related… Expand
The difference in ventilation heterogeneity between asthmatic and healthy subjects quantified using hyperpolarized 3He MRI.
In this pilot study, algorithms for quantitatively evaluating the distribution and heterogeneity of human ventilation imaged with hyperpolarized (HP) (3)He MRI were developed for the goal of… Expand
Mutations in BRAF and KRAS converge on activation of the mitogen-activated protein kinase pathway in lung cancer mouse models.
Mutations in the BRAF and KRAS genes occur in approximately 1% to 2% and 20% to 30% of non-small-cell lung cancer patients, respectively, suggesting that the mitogen-activated protein kinase (MAPK)… Expand
Intracranial compartment volumes in patients with enlarged ventricles assessed by magnetic resonance-based image processing.
Magnetic resonance image-based computerized segmentation was used to measure the volumes of the brain, gray and white matter components, and to identify regions with prolonged enhancement on… Expand

Image functional modeling (IFM) has been introduced as a method to simultaneously synthesize imaging and mechanical data with computational models to determine the degree and location of airway… Expand
Efficacy of a rapamycin analog (CCI-779) and IFN-gamma in tuberous sclerosis mouse models.
Tuberous sclerosis complex (TSC) is a familial tumor disorder for which there is no effective medical therapy. Disease-causing mutations in the TSC1 or TSC2 gene lead to increased mammalian target of… Expand

This review focuses on the state‐of‐the‐art of the three major classes of gas contrast agents used in magnetic resonance imaging (MRI)—hyperpolarized (HP) gas, molecular oxygen, and fluorinated… Expand
MRI of stroke using hyperpolarized 129Xe
Because there is no background signal from xenon in biological tissue, and because inhaled xenon is delivered to the brain by blood flow, we would expect a perfusion deficit, such as is seen in… Expand
