Neuronal activity causes local changes in cerebral blood flow, blood volume, and blood
oxygenation. Magnetic resonance imaging (MRI) techniques sensitive to changes in cerebral …

The authors review the theoretical basis of determination of cerebral blood flow (CBF) using
dynamic measurements of nondiffusible contrast agents, and demonstrate how parametric …

The T 1 perfusion model has worked well in brain functional studies where flow changes
are measured. Using selective and nonselective inversion pulses, a new method has been …

An expression is derived showing that the two-dimensional noise power spectrum of
computed X-ray tomography is proportional to mod G (k) mod 2/k where k is the radial spatial …

Interferon (IFN)-γ, is not only a marker of T H 1 CD4, CD8 and natural killer (NK) cells, it is
also a critical antiviral mediator which is central to the elimination of viruses from the CNS. In …

A general expression is derived for the noise due to photon counting statistics in computed X-ray
tomography. The variance is inversely proportional to the cube of the resolution …

Introduction Glioblastoma is the most common primary malignant brain tumor, and is refractory
to surgical resection, radiation, and chemotherapy. Human mesenchymal stem cells (…

Water‐ and fat‐suppressed projection MR imaging (WASPI) utilizes the large difference
between the proton T s of the solid organic matrix and the fluid constituents of bone to suppress …

The goal of this work was to develop a comprehensive understanding of the relationship
between vascular proton exchange rates and the accuracy and precision of tissue blood …

Investigators often study rats by μCT to investigate the pathogenesis and treatment of skeletal
disorders in humans. However, μCT measurements provide information only on bone …
