Experimental study on the accuracy of non-invasive temperature measurement by magnetic resonance in microwave ablation.
Aims: This study aimed to explore the accuracy of non-invasive temperature measurement based on proton resonance frequency (PRF) phase subtraction in microwave ablation (MWA).Methods and Material: The signal change of the agar phantom during the ablation process was monitored by the gradient echo se...

P < 0.05 indicated statistical significance.Results: The maximum error between the MRI temperature measurement and the standard value was 3.61°C, whereas the minimum and average errors were 0.01°C and 1.19°C ± 0.78°C, respectively.Conclusions: The temperature measurement technology, which is based on the PRF phase method, has good accuracy in MRI-guided MWA. pubtype: Academic Journal doctype: pictorial research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
