<b>MR Imaging of Large Multinodular Goiters:</b> Observer Agreement on Volume Versus Observer Disagreement on Dimensions of the Involved Trachea

Abstract

For the estimation of goiter volume, MR imaging has low intra- and interobserver variations. In contrast, the determination of tracheal dimensions using MR imaging has a high variability and, thus, is imprecise. Sonography significantly underestimates thyroid volume compared with MR imaging in patients with a large goiter.
