“…So far, there have been some papers published on the determination of the volume of the thyroid gland and thyroid nodules with 3D sonography [4][5][6][7][8]. However, to the best of our knowledge, no previous paper has been published in English language medical journals on the characterization of thyroid nodules with 3D sonography.…”

The aim of the study was differential evaluation of new and classical sonographic features of benign thyroid nodules and thyroid cancer with three-dimensional gray-scale sonography and evaluation of the effectiveness of the thin-slice surface rendered images in comparison with multiplanar reformation (MPR) presentation. Fifty-four thyroid nodules were interactively evaluated with thin-slice smooth surface rendering: shape in the c-plane (parallel to the probe) and evaluation of echogenicity, margins and calcification/microcalcification-like echogenic foci in the a-plane (plane of the probe). Evaluation of the level of agreement in readers' interpretation and between sonographic techniques was performed using the kappa statistic. Surface rendering permitted visualization of the shape of the nodule in the c-plane in all cases, in contrast to only up to 48% of cases in MPR evaluation. Lobulated nodule shape in the c-plane was 82-100% sensitive and 47-53% specific in diagnosis of carcinoma. Surface rendered images showed more calcification/microcalcification-like echogenic foci than MPR ones. The level of agreement between the observers in the evaluation of features of thyroid nodules and the agreement between features of thyroid nodules on MPR and surface-rendered images showed at least moderate reproducibility (kappa>or=0.41). Three-dimensional thin-slice surface rendering sonography appears to be a feasible and effective method for thyroid nodule evaluation.

“…Volumetric analyses of thyroid glands are routinely performed in 2D-US technique. However, several 3D-US approaches have been introduced in phantom and human studies showing highly correlative results for volumetric analyses compared with 2D-US [12,17,19,[26][27][28]. The possibility of post hoc evaluations in three different dimensions likewise CT or MRI is favorable in 3D-US.…”

Aims: To investigate the feasibility and accuracy of 3D-US extended field of view volumetric analyses acquired with mechanically-swept ultrasound probes with different measurement methods for large volume thyroid phantoms.Materials and methods: Fifteen thyroid phantoms with different shapes (regular, nodular, thickened isthmus) and volumes (50-400 mL) were created. Two different mechanically-swept US probes were used for the separate scanning of the left and right lobes: convex and linear probe. After specific modifications, the 3D-US datasets were stitched together to an extended field of view using predefined landmarks. Volumetric analyses were performed by conventional ellipsoid model and manual tracing methods. The correspondence of measured and reference volumes was calculated using Pearson’s correlation coefficients and limits of agreement according to Bland and Altman.Results: The C-probe proved feasible for the acquisition and processing of the three-dimensional ultrasound extended field of view images; very high levels of agreement (correlation coefficients for volume analyses: 0.9843-0.9992) were observed for all shapes and volumes investigated. The manual tracing method showed superior results in comparison to the ellipsoid model, but was more time consuming. The linear probe was only applicable for the 50 mL phantoms due to its limited field of view.Conclusions: The investigated mechanically-swept convex probe was suitable for the three-dimensional ultrasound extended field of view stitching of large volume thyroid phantoms. Accurate volume analyses could be carried out. The mechanically-swept linear probe is limited to a maximum of 50 m

“…Multiplanar imaging techniques such as computed tomography (CT) and magnetic resonance imaging provide excel- lent delineation of the thyroid from the surrounding tissues, either with or without contrast enhancement. 2,[10][11][12][13][14] The summation of areas technique has been well standardized and validated, and its reproducibility (with errors of 1%-2%) is very good. [12][13][14][15] On the other hand, these imaging techniques have some disadvantages, such as limited availability, a relatively high cost, the use of iodinated contrast media, and patient radiation exposure in the case of CT, that restrain their clinical applications for thyroid volume measurements in patients with specific conditions, such as Graves disease.…”
