Abstract
The aim of the present study was to examine the anatomical differences in volumetric and intraparenchymal vascular parameters between the two thyroid lobes of patients with goiter, using three-dimensional power Doppler ultrasound. A total of 89 outpatients with goiter, including 55 with autoimmune thyroid disease (ATD) and 34 with simple goiter (SG), were evaluated by three-dimensional power Doppler ultrasound. Volumetric and intraparenchymal vascular indices including vascularization index, flow index and vascular flow index of each lobe were measured using the Virtual Organ Computer-Aided Analysis system. In all patients with goiter, the volume and vascular indices (vascularization index, flow index and vascular flow index) of the right thyroid lobe were significantly greater than those of the left lobe ( p p
