Abstract
This document discloses, among other things, a system and method of creating a positive contrast magnetic resonance imaging (MRI) feature using a high transverse relaxation rate contrast agent.
Claims27
A method comprising:
- infusing a subject with a contrast agent, the contrast agent having a high transverse relaxation rate (R2);
- and
- generating magnetic resonance data in which the contrast agent contributes to a reduced longitudinal relaxation time (T1) in the subject.
A method comprising:
- applying a transverse relaxation time (T2) magnetic resonance imaging (MRI) pulse waveform to a subject;
- and
- acquiring data from the subject, wherein the data results from interaction with a contrast agent having a high transverse relaxation rate (R2).
An apparatus comprising:
- an MRI scanner configured to apply a longitudinal relaxation time (T1) sensitive magnetic resonance imaging (MRI) pulse waveform to a subject and acquire a positive contrast image from the subject, the acquired positive contrast image resulting from interaction with a contrast agent having a high transverse relaxation rate (R2).
A machine readable medium having executable instructions stored thereon for performing a method comprising:
- exciting a subject with a magnetic resonance pulse, the subject including a contrast agent having a high transverse relaxation rate (R2);
- and
- acquiring magnetic resonance data from the subject.
