PURPOSE To evaluate the relationship between quantitative parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and clinical stage of nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS Fifty-one newly diagnosed NPC patients received MRI examination on Philips Achieva 3.0 Tesla TX MR system. We used DCE-Tool (Philips Healthcare,(More)
OBJECTIVE The effectiveness of radiotherapy in nasopharyngeal carcinoma (NPC) is closely related to the radiosensitivity of the carcinoma; however, there is currently no effective method to predict radiosensitivity in NPC. We explored the predictive value of magnetic resonance diffusion-weighted imaging (MR-DWI) for radiosensitivity in NPC. Study Design(More)
OBJECTIVES/HYPOTHESIS Our objective was to predict the radiosensitivity of human nasopharyngeal carcinoma xenografts in nude mice models through an examination of early changes in apparent diffusion coefficient (ADC) values. STUDY DESIGN Randomized. METHODS BALB/c-nu nude mice (n = 20) were divided into two groups that were subcutaneously injected with(More)
