Differential diagnosis of CEUS in salivary malignant and benign lesions / 中国医学影像技术

ABSTRACT

Objective To explore the differential diagnostic value of CEUS in salivary malignant and benign lesions. Methods Totally 87 lesions (including 74 benign lesions and 13 malignant lesions) underwent CEUS, then the degree of homogeneous, enhancement type, margin, rim and enlarged area were observed and analyzed respectively. In addition, the enhancement degree, type of enter-in and wash-out were analyzed according to the time-intensity curves of lesions and surrounding glands. The differences between benign and malignant lesions were compared. Results The enhancement degree, enhancement type, degree of homogeneous, type of wash-in and wash-out had no statistically significant differences between benign and malignant lesions (all P≥0.05), while the enhancement margin, rim and enlarged enhancement area showed statistically significant differences between them (all P<0.01). Combining the latter three features, the differential diagnostic sensitivity, specificity and accuracy was 84.62% (11/13), 95.95% (71/74) and 94.25% (82/87), respectively. Conclusion The absent enhancement rim, ill-defined margin and enlarged enhancement area are features of salivary malignant lesions, and combining all of them has the great differentiated diagnostic efficacy to salivary malignant lesions.
