[Capabilities of ultrasound study in the differential diagnosis of neoplasms of the major salivary glands].

Seventy patients aged 20 to 75 years with suspected parotid gland disease were examined to study the capabilities of an ultrasound study in the diagnosis of neoplasms of the major salivary glands. B-mode ultrasonography and color Doppler imaging presented a means of detecting the presence of masses in the gland, their topography and dimensions, and specific vascularization, which allowed the option and scope of treatment to be planned.
