摘要

Abstract

Objective: To explore the clinical dosimetry of intensity modulated radiation therapy(IMRT) and three dimensional conformal radiotherapy(3D-CRT) for hepatocellular carcinoma treatment. Methods: Firstly, making radiotherapy schemes of IMRT and 3D-CRT for each patient among 45 ones in our hospital. Secondly, comparing PTVDmean, PTVDmin, PTVDmax, PTVDmax%, CI and HI. Finally, analyzing the dosage which endangers patient’s organs. Results: Comparation analysis results show that there is no statistical difference in PTVDmin (t=0.037,P>0.05), but there is significant statistical difference in PTVDmean, PTVDmax, PTVDmax/%, HI and CI between IMRT and 3D-CRT (t=35.631,t=4.136,t=3.428,t=2.123,t=15.996;P<0.05). Dosage analysis results show that IMRT remains in kidney, small intestine and spinal cord is remarkably less than the 3D-CRT. Conclusion:IMRT can effectively increase the radiation dose in target areas, reduce organ damage, and improve life quality of the patients.
