MRI新成像技术在腮腺肿瘤诊断中的应用进展

Advances of MRI used in parotid neoplasms

MRI具有良好的组织对比分辨力,能清晰的显示腮腺肿瘤本身及其周围的软组织,对于腮腺肿瘤的诊断具有非常重要的作用,已成为目前检查、诊断腮腺肿瘤理想的手段。随着MRI技术的发展,越来越多的新的成像技术应用于临床,包括弥散加权成像、MR波谱分析、MR腮腺导管成像、三维高分辨力成像等对腮腺肿瘤的诊断、术前评估、鉴别诊断等方面起着越来越重要的作用。本文综述了MRI新的成像技术在腮腺肿瘤中的应用进展。

MR imaging has high tissue resolution and could display parotid neoplasms itself and peripheral tissues .It plays an important role in the diagnosis of parotid neoplasms and has become an ideal tool in parotid imaging. With the development of MRI new techniques, including diffusion weighted imaging, MR spectroscopy, magnetic resonance sialography and 3D fast imaging employing steady state acquisition, the role of MRI in diagnosis and preoperative evaluation of pamtid neoplasms became more and more important. This article has reviewed different new examination tectmiques of MRI used in parotid neoplasms.
