- 論文の詳細を見る
The purpose of the current study is to evaluate the accuracy of MR thermometry for radiofrequency ablation (RFA) with hook-shaped electrodes. The objects were eight extracted bovine livers. The chemical shift change was calculated from MR images acquired with a spoiled gradient echo sequence and compared with the temperature directly measured with a thermocouple. Linear regression was established between them with a coefficient of -0.0110±0.0007 ppm/°C and errors were calculated as -0.50±7.50°C. MR thermometry is capable of monitoring temperature for RFA.
