Use of a curved‐array transducer to reduce interobserver variation in sonographic measurement of thyroid volume in healthy adults

Sonographic calculation of thyroid volume is used in the diagnosis and follow‐up of thyroid diseases. Since the calculated volume of thyroid lobes is highly influenced by the longest (ie, craniocaudal) diameter, we examined whether using a curved‐array transducer as opposed to a linear‐array transducer to measure the craniocaudal diameter would reduce interobserver variation.
