Respiratory frequency increases during exacerbations of COPD (ECOPD). We hypothesized that this increase can be detected at home before ECOPD hospitalization.To test this hypothesis, respiratory frequency was monitored at home daily for 3 months in 8

A combined approach to 3D radial and spiral MRI is presented. Although radial and spiral MRI have some similarities from the viewpoint of their mathematical properties, sequence design, and reconstruction procedures, they are usually implemented in s

Lung functional magnetic resonance imaging (MRI) has become a reality using different inert hyperpolarized gases, such as 3 He and 129 Xe, which have provided an extraordinary boost in lung imaging and has also attracted interest to other chemically

An approach for an animal MRI-compatible ventilator is described, which might be useful for some applications, such as those dependent on gas flow. The ventilator has been optimized for small rodents, although the instrument may easily be conveyed to

A method for pathway selection in a multiple spin-echo pulse sequence applying crusher gradients before and after each pi pulse, to dephase unwanted pathways, is described. This method selects the only pathway that would contribute to the measurable

Diffusion weighted 19F images of rat lung in vivo using SF6 are presented. Projection-reconstruction images were acquired by filling the rat lung with a mixture of SF6 and air, during 64 successive apneas. Each apnea lasted for 6 s, the time required
