40 patients with clinically palpable salivary gland masses were included in a prospective study to compare magnetic resonance imaging to computed tomography. MRI has proved superior to CT not only in imaging primary lesions but also in diagnosing local and regional recurrences. In evaluating border structures, signal intensity, T1- and T2-values of space occupying lesions, we can determine the tumour status. Besides, we can define to some extent the internal architecture of the salivary gland or intra-resp. periglandular lymph node masses. Better contrast resolution and more specificity can be obtained by the use of contrast medium gadolinium-DTPA. Even small intraglandular and periglandular masses can be clearly distinguished from the sourrounding structures. At present, magnetic resonance imaging offers the diagnostic potency of both sonography and computed tomography. The advantages of MRI and our present indications in imaging salivary gland masses are discussed.
40例临床上可触及唾液腺肿块的患者被纳入一项前瞻性研究，以比较磁共振成像（MRI）和计算机断层扫描（CT）。MRI已被证明不仅在成像原发性病变方面优于CT，而且在诊断局部和区域复发方面也更具优势。在评估边界结构、占位性病变的信号强度、T1和T2值时，我们可以确定肿瘤状态。此外，我们可以在一定程度上定义唾液腺或呼吸内/腺周淋巴结肿块的内部结构。使用造影剂钆-DTPA可以获得更好的对比度分辨率和更高的特异性。即使是小的腺内和腺周肿块也能与周围结构清楚地区分开来。目前，磁共振成像兼具超声检查和计算机断层扫描的诊断效能。本文讨论了MRI的优势以及我们目前在唾液腺肿块成像方面的适应症。
