US Patent:

Appl. No.:

09/682687

Inventors:

Thomas K. F. Foo - Rockville MD
Zahi A. Fayad - New York NY

Assignee:

GE Medical Systems Global Technology Co., LLC - Waukesha WI

International Classification:

A61B 505

US Classification:

600410, 600420, 324306, 324309

Abstract:

The invention includes a technique for efficient multi-slice fast spin echo image acquisition with black blood contrast in cardiac imaging. The technique includes applying a non-selective inversion pulse, followed by a re-inversion pulse that is slice-selective over a region encompassing a plurality of slice selections. Execution of a series of RF excitation pulses with fast spin echo readout is timed such that signal from blood is near a null point before acquiring data for each spatial slice. For greater contrast consistency, the flip angles for the excitation pulses occurring before the null point can be reduced, and those occurring after the null point can be increased.

US Classification:

600423, 324318, 324322

Abstract:

The magnetic resonance catheter antenna includes a first tube having a proximal end and a distal end. A litz wire has a first end and a second end and is looped within the first tube such that the first end and the second end are disposed at the proximal end. A guide wire is disposed within the first tube. A multifilament or solid wire may be used instead of a litz wire. At least the looped portion of the wire is insulated.

International Classification:

G06K 9/00

US Classification:

382128, 382131

Abstract:

A multicontrast-weighted acquisition of three images is performed with an MRI system. Each image is normalized and then mapped to a separate color channel. A composite color image is formed by combining all the color channels, and this image is displayed or analyzed to identify different tissue types therein.

Abstract:

The present invention is directed to synthetic nanoparticles useful as imaging agents for use in MRI, CT, Gamma-scintigraphy, or optical imaging techniques. The synthetic nanoparticles comprise at least one apolipoprotein that is not an apoB lipoprotein, at least one amphipathic lipid, and at least one metallic or non-metallic contrast agent linked through a chelator to a component of the nanoparticle, wherein the one metallic or non-metallic contrast agent is present in an amount of between 5% to about 50% (w/w) of the nanoparticle, and the nanoparticle has a diameter of from about 5 nm to about 50 nm. Compositions and kits comprising the synthetic nanoparticles and methods of making and using the same are also provided.

A second balloon has a longitudinal axis. The second balloon is disposed about the first balloon. A plurality of longitudinally extending grooves are disposed in one of an external surface of the first balloon and the internal surface of the second balloon. A first wire is disposed in at least one of the grooves. A second wire is disposed in at least a second one of the grooves.
