Today ultrasound, often integrated with CT and NMR, is used in the differential diagnosis of parotid masses. Color-Doppler Sonography is a recently introduced method which makes it possible to evaluate intra- and perilesional vascularization and to perform a hemodynamic study of the area being explored. Using an Acuson 12P ultrasound unit 21 patients with surgically treated parotid neoformations were examined. All had previously undergone traditional ultrasound and CT. An abundant vascularization, both intralesional and peripheral, was found in 4 malignant lesions, in one intraglandular granulomatose lymph adenopathy, in one pleomorphic adenoma of the deep lobe and in one case of Sjögren's syndrome. In the remaining cases (7 pleomorphic adenomas and 7 cystoadenolymphomas) vascularization was either totally absent or only slightly visible in the periphery. These preliminary results would appear to indicate that the presence of hypervascularization testifies to a malignant lesion or to an inflammatory disorder. The Color-Doppler Sonography can provide a useful adjunct to conventional ultrasound, increasing diagnostic accuracy in cervical-parotid masses.
如今，超声检查（通常与CT和核磁共振成像相结合）被用于腮腺肿块的鉴别诊断。彩色多普勒超声检查是一种最近引入的方法，它能够评估病变内部及周围的血管形成情况，并对所探查区域进行血流动力学研究。使用一台Acuson 12P超声设备，对21例接受过腮腺新生物手术治疗的患者进行了检查。所有患者此前均接受过传统超声检查和CT检查。在4例恶性病变、1例腺内肉芽肿性淋巴结病、1例深叶多形性腺瘤以及1例干燥综合征患者中，发现病变内部及周边血管丰富。在其余病例（7例多形性腺瘤和7例囊性腺淋巴瘤）中，血管形成要么完全缺失，要么仅在周边略有可见。这些初步结果似乎表明，血管增多提示为恶性病变或炎症性疾病。彩色多普勒超声检查可为传统超声检查提供有用的辅助手段，提高颈部腮腺肿块的诊断准确性。
