High frequency ultrasonography and computerized tomography in the diagnosis of salivary gland lesions

ABSTRACT

Sonography and computed tomography play complimentary roles in imaging lesions of the salivary glands. The present investigation was carried out to evaluate the role of high frequency ultrasonography [HF US] and computerized tomography [CT] in the diagnosis of salivary gland lesions .Moreover, the diagnosis was confirmed by histopathological examination. Fourteen patients suffeingr from swelling and/ or pain of one of the major salivary gland were referred from the out patient dental clinic in Alzhraa hospital. Clinical and radiological examinations. HF US andCT were carried out for all patients and it seems that the two techniques are equally effective. Therefore, HF US can replace CT, as it is non-invasive technique and less expensive. Doppler US gives more information about intra and prelesional vascularaization and soft tissue component surrounding the blood vessels
