In vivo intermolecular double-quantum imaging on a clinical 1.5 T MR scanner

Magn Reson Med. 2000 Mar;43(3):335-41. doi: 10.1002/(sici)1522-2594(200003)43:3<335::aid-mrm3>3.0.co;2-1.

Abstract

A novel MRI method based on the intermolecular double-quantum coherence (DQC) for soft tissues is described. DQC images of human brain were obtained for the first time on a whole-body 1.5 T scanner. The combination of quantum and classical formalisms was used to characterize multiple-quantum coherences, and to aid in the design of a DQC imaging sequence. The theoretical analysis suggests that signals from the intermolecular DQCs have higher sensitivity than those from the zero-quantum coherence (ZQC) for human brain, and the sensitivity increases with increased field strength. The DQC signal may provide a new form of contrast for MRI.
