Ultrasonographic texture characterization of salivary and neck masses using two-dimensional gray-scale clustering

Dentomaxillofac Radiol. 1997 Nov;26(6):332-6. doi: 10.1038/sj.dmfr.4600295.

Abstract

Objectives: To evaluate the clinical usefulness of texture analysis in ultrasonography (US) of head and neck masses.

Methods: Sixty-one cases with salivary or neck masses were examined by US with a linear 7.5MHz array. Images were digitized and quantitatively evaluated by two-dimensional gray-scale clustering using two texture indices, M and SD, as measures of coarseness and homogeneity respectively.

Results: Coarseness of Warthin's tumors was significantly higher than that of the other salivary tumors. Malignant lymphomas had finer texture values than other lymph node lesions.

Conclusions: Quantitative texture analysis appears to be a useful complement in diagnostic US.
