|Morphologic change of a thyroid nodule with initial benign US and cytology after fine needle aspiration biopsy: Incidence and significance|
Methods and Materials
From October 2003 to December 2004, among patients who underwent thyroid FNAB, 550 patients who had thyroid nodules with initial benign US and cytologies were included in this study. Standard references were established by pathologic results, follow-up cytologic results, or follow-up US. We evaluated the incidence of morphologic changes to suspicious US findings of these thyroid nodules after FNAB and their malignancy rates. We evaluated the US features affecting the morphologic changes after FNAB in these patients.
