Quantitative Analysis of 3-Dimensional Volumetry and Histogram of Thyroid Gland on Neck Computed Tomography for Patients with Hashimoto's Thyroiditis

Volumetric measurement of thyroid gland has been applied in various imaging modalities to diagnose thyroid diseases, such as goiter, nodule, thyroiditis, and Graves’ disease (1, 2). Shu et al. (3) have suggested that spiral computed tomography (CT) is an easy, accurate, reliable, reproducible modality to predict the volume of thyroid. Recently, three-dimensional (3D) CT volumetry has been introduced to measure the volume of thyroid (3). Iterative and semi-automated segmentation can be applied in a multimodal workstation to more accurately measure the volume of thyroid using 3D CT volumetry.
