Objective: The dynamic microvascularization of focal salivary gland lesions was evaluated by contrast-enhanced ultrasound(CEUS) and Color Doppler sonography.Methods: A total of 168 patients with 183 major salivary gland lesions (mean age, 56 years; age range, 12 to 83 years) underwent gray-scale ultrasonography, Color Doppler (CD), and CEUS.The CD and CEUS patterns were classified into three types(scores 0-3).Combined score grades were calculated based on the CD and CEUS pattern scores.The time-intensity curve (TIC)parameters of CEUS were then analyzed.Sensitivity, specificity,negative predictive value, and positive predictive value of combined score grades were also calculated.
