Abstract
In this paper, lasers are described in the framework of magnetic resonance imaging (MRI) and
spectroscopy techniques. This paper is about lasers that can reduce the errors in imaging and increase the
sensitivity of spectroscopic measurements, helping scientists detect biochemical changes, particularly in
tissues. The applications of lasers in exciting atoms and molecules (to increase magnetic signals) and
thus imaging quality and optical modulation of magnetic systems are also presented, in order to perform
spectroscopic analysis better. This study also investigates new developments in the integration of laser
technologies with MRI and spectroscopy, in particular for using lasers in polarization of noble gases to
maximize medical contrast for the imaging. It also illustrates lasers’ involvement in producing quantum
events that influence the nuclear magnetic responses of its instruments for improved diagnostics and
scientific study. Also, some technical and practical issues related to this field are addressed before
considering a vision into lasers in imaging and spectroscopic techniques .
