Texture characterization in ultasonograms of the thyroid gland

Histogram and gray level co-occurrence matrix on gray-scale ultrasound images for diagnosing lymphocytic thyroiditis

“…Although USE showed high diagnostic performances for diagnosing DTD, USE needs software more advanced than those used in conventional US and this advanced technology may be available only with more costs and may need a longer performance time than gray-scale US exams. Texture analysis has been considered instead because it can provide objective and quantitative information about the image patterns of the thyroid parenchyma [23]. The methods used in this study were based on both first-order texture features derived from a histogram and second-order features derived from a GLCM [24,25].…”

Application of Texture Analysis in the Differential Diagnosis of Benign and Malignant Thyroid Nodules: Comparison With Gray-Scale Ultrasound and Elastography

“…Texture analysis can be used to quantify spatial variation of gray levels in a specified ROI that is not discernible to the human eye [27][28][29][30][31][32][33][34]. An objective and quantitative approach using texture analysis will be of great benefit if a sufficiently high degree of accuracy comparable to that of gray-scale ultrasound or elastography can be achieved in differentiating benign and malignant thyroid nodules.…”

A Segmentation Method and Comparison of Classification Methods for Thyroid Ultrasound Images

“…Maria E. Lyra [13] et al proposed a method to characterize the thyroid in ultrasound images, Xiangbin Wang [14] et al In content-based image retrieval, technology could be applied to medicine the query criteria itself is an image or the description of image content, Dimitris Maroulis [15] et al The robustness of textural features on speckle noise is of vital importance for ultrasound imaging, Dimitris Maroulis [16] et al The inherent speckle noise in the images produced by this technique introduces uncertainty; we proposed a novel fuzzy feature extraction method to encode local texture, Si Luo [17] et al proposed to evaluate whether ultrasound elastography can be used as a screening tool to reduce the number of FNA procedures on benign thyroid nodules.…”
