Abstract:
To evaluate the effectiveness of ultrasound (US) and computed tomography (CT) in diagnosing salivary gland neoplasms, 99 patients (benign tumor--72; salivary cyst--4 and malignant tumor--23) were examined. Also, 84 ultrasound-guided fine-needle aspiration biopsies were performed. Both US and CT showed high diagnostic potential in dealing with bulky lesions of the glands. Although sensitivity was 55.6 and 66.7, specificity--98.2 and 98.7 and accuracy of differential diagnosis between benign and malignant lesions--87.6 and 91.8%, respectively, differential diagnosis of benign and malignant tumors on the basis of US and CT evidence alone is not possible.
