The neodymium yttrium aluminium garnet ( Nd-YAG) laser was applied for interstitial thermotherapy under low power of 2 W, 5 W and 10 W respectively, and for heating time of 800 s, 800 s and 600 s respectively, meanwhile the control group was established.
Objective:To investigate the influence of different therapeutic parameters on the therapeutic effect, and then to choose and optimize these parameters.
ConclusiontDuring a LITT treatment, the Rx should be based on the general consideration of different biological properties and the laser wavelength,laser power and the laser probe exposure duration.
Laser-induced interstitial thermotherapy (LITT) performed under MRI guidance results in precise and reproducible areas of induced necrosis with a local control of 94 %, and with an improved survival rate.
