76 patients with pathologically confirmed papillary thyroid carcinoma (PTC) underwent preoperative thyroid T2-weighted (T2WI) MRI examination in this retrospective study. Using texture analysis for acquired T2WI imaging, entropy was found significantly higher in PTC patients with extrathyroidal extension (ETE) than without ETE, and thus considered an independent index for predicting PTC patients with ETE. With this finding, we therefore consider that preoperative T2WI-based texture features may be valuable for identifying ETE status in PTC patients and may help customize treatment strategies.
