1. Description of elastographic features of various parotid masses, with definitive histological confirmation, in comparison with CDUS, contrast enhanced ultrasound (CEUS), and MRI findings. 2. Explanation of technical issues of various US elastography methods and their application in the parotid. 3. Review of epidemiology, clinical presentation, state of the art work up, differential diagnosis and treatment options.

1. Diagnostic issues of parotid masses. 2. State of the art imaging and literature review. 3. US techniques available for parotid lesion evaluation and their use in the malignant/benign differentiation: qualitative elastography with Ueno score, semi-quantitative strain ratio measurements and carotid artery in vivo compression (ECI index). 4. CEUS as an alternative to MRI for vascularization assessment. 5. Parotid masses at US elastography, CEUS and MRI in correlation with histopathology, with image review of representative cases from our cohort of 48 patients with parotid lesions (18 pleomorphic adenomas, 14 Warthin tumors, 8 intraparotid reactive lymphnodes, 4 carcinomas, 3 parotiditis, 1 lymphoma). 6. Qualitative and semiquantitative Stiffness and CEUS patterns correlating with malignancy. 7. Discussion on differential diagnosis and the role of the various imaging modalities. 8. Conclusion.
