随着现代医学科学的发展,医学影像学在鼻咽癌诊断中发挥了十分重要的作用。MRI具有良好的软组织对比度和多参数成像,可清晰地从形态学和功能改变方面为肿瘤的定位定性提供丰富的诊断信息;应用对比剂增强和压脂序列扫描是目前评估鼻咽癌病灶范围、分级分期的最佳影像学手段。CT扫描在诊断颅底骨质侵犯方面具备优势。PET-CT则在发现原发灶和远处转移方面具有较高的敏感性。全文就目前各种不同影像学检查对鼻咽癌的诊断进行评价,并着重介绍了MRI的应用。
With the development of modern medical science, medical imaging plays a very important role in the diagnosis of nasopharyngeal carcinoma. MRI has good soft tissue contrast and multi-parameter imaging, can clearly provide morphological and functional changes in tumor localization and qualitative diagnosis provides a wealth of information; contrast enhanced contrast and lipid-scanning sequence is the assessment of the extent of NPC lesions, Grading staging the best means of imaging. CT scan in the diagnosis of skull base bone invasion have the advantage. PET-CT is highly sensitive in detecting primary lesions and distant metastases. The full text of the current various imaging studies to evaluate the diagnosis of nasopharyngeal carcinoma, and focuses on the application of MRI.
