MR thermometry near metallic devices using multispectral imaging

The lack of a technique for MR thermometry near metal excludes a growing patient population from promising treatments such as MR‐guided focused ultrasound therapy. Here we explore the feasibility of multispectral imaging (MSI) for noninvasive temperature measurement in the presence of strong field inhomogeneities by exploiting the temperature dependency of the T1 relaxation time.
