Noninvasive Temperature Measurement Using MRI Based on T2 Relaxation Time

Yuhua Peng, Honghong Dong, Xiaoying Tang

Abstract

Intraoperative temperature measurement using magnetic resonance imaging has shown a great value as a noninvasive method. T2 relaxation time is one of the magnetic resonance imaging(MRI) parameters, theoretically, it is related to temperatures and signal amplitudess. in this paper we tried to find the relationship between temperature and porcine liver's T2 relaxation time by using CPMG sequence under different temperatures. Maybe this method will provide temperature monitoring during clinical cancer hyperthermia with a good effect.
