All studies aimed at the differential diagnosis of benign vs. malignant PGTs or the identification of the commonest PGT subtypes were identified, and five studies were found that focused on deep learning-based differential diagnosis of PGTs. A tumor of the parotid salivary gland arises from an overgrowth of cells. In the parotid, this may threaten local structures and so prompt surgical intervention is required. PMC Although high-grade malignancies of the parotid gland usually have poorly defined margins, low signal intensity on T2-weighted images and invasion of surrounding structures, tumour margins, homogeneity, and signal intensity are not discriminative factors for correctly predicting benign or malignant tumours [12]. Berlin Heidelberg: Springer-Verlag; 2007. pp. This is reflected in excellent survival rates of 90% at 5 years, which drops to 55% at 20 years.
