Fig. 1From: Early evaluation of irradiated parotid glands with intravoxel incoherent motion MR imaging: correlation with dynamic contrast-enhanced MR imagingFlowchart describes the procedures of MR examinations and radiotherapy (RT) for patients with nasopharyngeal carcinoma. Pre-MR and post-MR are the MR examinations within 2Â weeks before RT (pre-RT) and 4Â weeks after RT (post-RT), respectively.
