Fig. 1From: Can the apparent transverse relaxation rate (R2*) evaluate the efficacy of concurrent chemoradiotherapy in locally advanced nasopharyngeal carcinoma? a preliminary experienceA young man with nasopharyngeal carcinoma (AJCC stage III). (a) Axial enhanced fat suppression T1WI before CCRT with lesions located on the right side. (b) Axial enhanced fat suppression T1WI at 3 months after the end of CCRT indicates stable disease (SD) according to RECIST 1.1; the patient was included in NRG. (c) R2* value in the ROI was 36.40 Hz on the R2* color-coded map before CCRT. (d) R2* value in the ROI was 34.70 Hz at 3 months after the end of CCRT.
