Journal ArticleDOI
Magnetic resonance imaging of perfusion using spin inversion of arterial water.
TL;DR: Perfusion images of a freeze-injured rat brain have been obtained, demonstrating the technique's ability to detect regional abnormalities in perfusion.

TL;DR: This approach allows quantitative perfusion images to be obtained completely non‐invasively at the resolution of 1H MRI, and is useful in the clinical and investigational evaluation of organ physiology.
Journal ArticleDOI
Detection of single mammalian cells by high-resolution magnetic resonance imaging.
TL;DR: The detection of single mammalian cells, specifically T cells (T lymphocytes) labeled with dextran-coated superparamagnetic iron oxide particles, using magnetic resonance microscopy lays the foundation for the approach to tracking the movement of a specific cell type in live animals and humans.
Journal ArticleDOI
NMR Measurement of Perfusion Using Arterial Spin Labeling Without Saturation of Macromolecular Spins
TL;DR: The theory and experiments are presented to estimate tissue perfusion, magnetization transfer rate constants, and spin‐lattice relaxation times of water and macromolecular spins in rat brain.
Journal ArticleDOI
Multi‐Slice MRI of Rat Brain Perfusion During Amphetamine Stimulation Using Arterial Spin Labeling
TL;DR: It is shown that no signal loss occurs due to MTC effects when the two‐coil system is used for MRI of rat brain perfusion, enabling three‐dimensional perfusion imaging.
