CT及MRI是目前诊断腮腺肿瘤的最重要影像技术,但腮腺肿瘤组织结构复杂,常规CT及MRI检查技术对腮腺肿瘤定性诊断有时仍较困难,因此,CT及MRI新技术逐渐应用于腮腺肿瘤性病变的研究及临床,其中CT灌注技术、磁共振的扩散成像(diffusion weighted imaging,DWI)、磁共振波谱(magnetic resonance spectroscopy,MRS)及磁共振腮腺导管成像技术和面神 CT and MRI are the most important imaging techniques for the diagnosis of parotid tumors. However, the structure of the parotid gland tumor is complicated. Conventional CT and MRI techniques are still sometimes difficult to diagnose parotid tumors. Therefore, the new CT and MRI techniques are gradually applied to parotid tumors CT perfusion techniques, diffusion weighted imaging (DWI), magnetic resonance spectroscopy (MRS) and magnetic resonance imaging of parotid duct and facial deities
