Implication

This review discusses MR thermometry methods for precise temperature monitoring during thermal therapies, highlighting their implications for treatment effectiveness.

Key Points

The aim is to provide an overview of MR thermometry techniques for accurate temperature monitoring during thermal therapies.
Overview of MRI principles including signal generation and image formation.
Discussion of four MR thermometry methods: PRF shift, T1-based, T2-based, and diffusion-based techniques.
Analysis of the advantages and limitations of each method within various tissues.
PRF method is identified as the gold standard for temperature monitoring due to its simplicity and accuracy.
T1- and T2-based methods offer viable alternatives in tissues where PRF is ineffective, such as fat and bone.
Diffusion-based thermometry has potential for specialized applications despite challenges like motion sensitivity.
