OBJECTIVE
The role of computed tomography (CT) and magnetic resonance imaging (MRI) in the diagnosis of parotid tumors was investigated.
METHODS
Forty patients with the clinical suspicion of a parotid mass underwent both CT and MRI of the parotid region. Two radiologists independently assessed the CT and MRI results with respect to tumor localization, tumor margin characteristics, and infiltration of surrounding tissue. Histopathologic specimens were obtained in all cases and correlated with the radiologic findings.
RESULTS
The sensitivity and specificity of CT and MRI were nearly the same for tumor location, tumor margin, and tumor infiltration.
CONCLUSION
The 2 imaging techniques provided the same information with respect to the presurgical planning and contribute to the diagnosis and therapy planning of parotid tumors.
目的
研究计算机断层扫描（CT）和磁共振成像（MRI）在腮腺肿瘤诊断中的作用。
方法
40例临床怀疑腮腺肿块的患者接受了腮腺区域的CT和MRI检查。两名放射科医生独立评估CT和MRI结果，包括肿瘤定位、肿瘤边缘特征以及周围组织浸润情况。所有病例均获取了组织病理学标本，并与影像学结果进行关联。
结果
CT和MRI在肿瘤位置、肿瘤边缘和肿瘤浸润方面的敏感性和特异性几乎相同。
结论
这两种成像技术在术前规划方面提供了相同的信息，有助于腮腺肿瘤的诊断和治疗规划。
