ABSTRACT
Objective To evaluate the diagnostic values of diffusion tensor imaging(DTI)in early radiation-induced brain injury of the temporal lobes.Methods Conventional and MR diffusion tensor imaging examinations were performed in 23 patients following radiotherapy for nasopharyngeal carcinoma(NPC)and in 28 age-matched healthy controls.Isotropic apparent diffusion coefficient(ADCiso)and anisotropic index were measured in the white matter on both of the temporal lobes.Results The value of ADCiso,fractional anisotropy(FA),relative anisotropy(RA)and 1 minus volume ratio(1-VR)were(644.08?56.80)?10-6 mm2/s,0.394?0.074,0.344?0.075 and 0.182?0.072 respectively.In comparison with control group,these values were significant decreased(P
