Abstract
A method and system for imaging using labeled contrast agents and a magnetic resonance imaging (MRI) scanner are provided. The method comprises performing a prescan at a frequency selected to be substantially similar to a frequency of the labeled contrast agent and performing an examination scan at the frequency of the labeled contrast agent substantially immediately after administering the labeled contrast agent to a subject.

A method for imaging using labeled contrast agents and a magnetic resonance imaging (MRI) scanner comprising:
- performing a prescan on a subject at a resonance frequency selected to be substantially similar to a resonance frequency of a labeled contrast agent, prior to administration of the labeled contrast agent to the subject;
- performing an examination scan at the resonance frequency of the labeled contrast agent substantially immediately after administering the labeled contrast agent to the subject;
- and
- obtaining an image of the subject in order to characterize a metabolic region of interest.
A method for imaging with a magnetic resonance imaging (MRI) scanner comprising:
- performing a prescan on a subject at a resonance frequency different than but substantially similar to a resonance frequency of a labeled contrast agent in order to calibrate the MRI scanner for a given subject, prior to administration of the labeled contrast agent to the subject;
- performing an examination scan substantially immediately after administering the labeled contrast agent to the subject, wherein the examination scan is performed at a resonance frequency corresponding to the labeled contrast agent;
- and
- obtaining an image of the subject in order to characterize a metabolic region of interest.
A system configured for imaging using a magnetic resonance imaging (MRI) scanner, the system comprising:
- a radiofrequency coil tunable at frequencies corresponding to resonating frequencies of a selected labeled contrast agent and a prescan resonance frequency;
- wherein the MRI scanner is configured to perform a prescan at a prescan resonance frequency in order to calibrate the MRI scanner, prior to administration of the labeled contrast agent to a subject;
- and,
- wherein the MRI scanner is further configured to perform an examination scan at the labeled contrast agent resonance frequency substantially immediately after administering a labeled contrast agent to the subject;
- and
- wherein the MRI scanner is configured to obtain an image of the subject from the examination scan characterizing a metabolic region of interest.
