Fast Metabolic Imaging Of Systems With Sparse Spectra Using Spiral Csi

View page
US Patent:
20080057587, Mar 6, 2008
Filed:
Sep 1, 2006
Appl. No.:
11/469801
Inventors:
Dirk Mayer - Menlo Park CA, US
Yakir Levin - Palo Alto CA, US
Daniel Spielman - Menlo Park CA, US
Ralph Eugene Hurd - Milpitas CA, US
Assignee:
The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA
General Electric Company - Schenectady NY
International Classification:
G01N 33/00
US Classification:
436 34
Abstract:
A method of imaging the individual components of systems with sparse spectra using magnetic resonance imaging including the steps of a) exciting nuclei of labeled components using a MRI pulse sequence, b) selecting a proper spectral window to avoid/minimize signal overlap of aliased frequency components. In step a) preferably a spiral chemical shift imaging (spCSI) sequence is employed. In a preferred embodiment, hyperpolarized nuclei of C are used for labeling in a pyruvate substrate with metabolites of lacatate, alanine, and bicarbonate.

Magnetotactic Bacteria Mri Positive Contrast Enhancement Agent And Methods Of Use

US Patent:
20100135912, Jun 3, 2010
Filed:
Nov 30, 2009
Appl. No.:
12/627299
Inventors:
Sanjiv S. Gambhir - Portola Valley CA, US
Michael Benoit - Menlo Park CA, US
A. C. Matin - Stanford CA, US
Yoram Barak - Menlo Park CA, US
Shay Keren - Haifa, IL
Dirk Mayer - Menlo Park CA, US
International Classification:
A61K 49/08
C12N 1/20
US Classification:
424 932, 4352521
Abstract:
Magnetic resonance imaging (MRI) is enhanced by contrast agents such as superparamagnetic iron-oxide (SPIO) particles that resemble magnetite particles produced by magnetotactic bacteria. AMB-1 produces positive MRI contrast when generating ultrasmall magnetite particles (10-40 nm diameter). Positive MRI contrast permits clearer distinction from image voids compared to negative contrast. T1-weighted MRI showed that such bacteria increased positive contrast 2.2-fold (p

US Patent:
20120128593, May 24, 2012
Filed:
Sep 29, 2011
Appl. No.:
13/248247
Inventors:
Yi-Fen YEN - Menlo Park CA, US
John D. Mackenzie - Palo Alto CA, US
Dirk Mayer - Redwood City CA, US
Daniel M. Spielman - Menlo Park CA, US
International Classification:
A61K 49/10
C07C 59/19
C12Q 1/02
US Classification:
424 93, 435 29, 562577
Abstract:
