[Cyto-histological correlation in the management of parotid gland tumors: A retrospective study of 160cases]. The most important initial step is identification of the facial nerve and its course through the substance of the parotid gland. The parotid glands are the largest salivary glands in humans and are frequently involved in disease processes. This study aimed to investigate the utility of the apparent diffusion coefficient (ADC) value, texture features, and their combination for the differential diagnosis of parotid gland tumors. Receiver operating characteristic curves were constructed to determine the predictive values of echogenicity, heterogeneity, and vascularity on color Doppler. it in the differential diagnosis from those entities commented on above, taking into account the fact that the experience and ocurrence of acinic cell carcinoma of the parotid gland. In the absence of an easily recognizable mucous cell population, the diagnosis is challenging, often requiring ancillary studies such as special (mucin) stains, immunohistochemistry, and detection of classical MEC 8600 Rockville Pike To create a predictive score for the discrimination between benign and malignant parotid tumors using elastographic parameters and to compare its sensitivity and specificity with standard ultrasound.
