Abstract

Magnetic resonance imaging evaluations of nine histopathologically confirmed minor salivary gland tumors were made retrospectively and compared with evaluations of images obtained by computed tomography. All tumors had low-to-intermediate T1 signal intensities and intermediate-to-high T2 signal intensities. Malignant tumors had an irregular margin in all but one case. Benign tumors invariably had well-defined margins. In terms of tumor margination, the magnetic resonance imaging findings correlated well with the histopathologic findings. Magnetic resonance imaging demonstrated the internal architecture of the minor salivary gland tumors multidirectionally and was superior to computed tomography in this respect and in the ability to locate the tumors.

小唾液腺的影像学肿瘤

回顾性对9例经组织病理学证实的轻微唾液腺肿瘤进行磁共振成像评价，并与计算机断层成像评价进行比较。所有肿瘤均具有低至中等T1信号强度和中至高T2信号强度。恶性肿瘤除一例外均有不规则边缘。良性肿瘤总是有明确的边缘。在肿瘤边界方面，磁共振成像结果与组织病理结果吻合良好。磁共振成像多方向显示小唾液腺肿瘤的内部结构，在这方面和定位肿瘤的能力上优于计算机断层扫描。
