Optical sonography in differential diagnosis of thyroid nodes

Sensitivity, specificity and accuracy of optical ultrasonography in differential diagnosis of thyroid nodules were estimated. Sensitivity of ultrasonography in the diagnosis of thyroid malignancies was 0.75, specificity 0.62, accuracy 0.67. Sensitivity of ultrasonography in the diagnosis of thyroid adenoma was 0.85, specificity 0.62, accuracy 0.73. Sensitivity of optical sonography in the diagnosis of CCH was 0.62, specificity 0.61, accuracy 0.7. Optical sonography ensures differentiation of CCH and follicular adenoma, CCH and thyroid cancer, follicular adenoma and thyroid cancer. Sensitivity, specificity and accuracy of ultrasonography in differential diagnosis of FA and thyroid cancer are 0.85, 0.62, 0.73 and 0.8, 0.71, 0.7, respectively.
