Association between the sonographer's experience and diagnostic performance of IOTA simple rules.

Background: To validate the clinical value of simple rules in distinguishing malignant adnexal masses from benign ones and to explore the effect of simple rules for experienced and less-experienced sonographers.

Methods: Patients with persistent adnexal masses were enrolled between November 2013 and December 2015. All masses were proven through histological examinations.

Distribution patterns of microcalcifications in suspected thyroid carcinoma: a classification method helpful for diagnosis.

Purpose: The aim of this study was to compare the distribution patterns of microcalcifications in thyroid cancers with benign cases.

Methods: In total, 358 patients having microcalcifications on ultrasonography were analysed. Microcalcifications were categorised according to the distribution patterns: (I) microcalcifications inside one (a) or more (b) suspected nodules, (II) microcalcifications not only inside but also surrounding a suspected single (a) or multiple (b) nodules, and (III) focal (a) or diffuse (b) microcalcifications in the absence of any suspected nodule.

Papillary thyroid carcinoma with massive metastasis in the uterine corpus: a case report.
