应用高频超声探查甲状腺结节内钙化灶的临床研究

[目的]探讨应用高频超声探查甲状腺结节内钙化灶的临床意义。[方法]对93例共121个伴有钙化灶的甲状腺结节的超声声像图进行分析,并与病理结果进行对照。[结果]按照钙化分型,伴微钙化结节40个,粗钙化结节72个,周边钙化结节5个,孤立性钙化结节4个。其中伴微钙化结节的恶性率为87.50%（35/40）,伴粗钙化结节的恶性率为13.89%（10/72）,微钙化及粗钙化结节的良恶性比率之间差异有显著性意义（P〈0.05）。周边钙化及孤立性钙化结节均为良性。[结论]高频超声可以清晰地显示甲状腺结节内不同类型的钙化灶,对于结节性质的判定具有重要的临床意义。

Clinical study of detection of calcifications in nodules of thyroid gland by high-frequency ultrasonogrphy

[Objective] To discuss the clinical value of calcifications in nodules of thyroid gland detected by high-frequency ultrasonogrphy.[Methods] The ultrasound images of 93 patients including 121 nodules with calcifications were analyzed and compared with pathological examinations.[Results] According to the calcification types,40 nodules with microcalcification,72 nodules with intranodular coarse calcification,5 nodules with peripheral calcification and 4 nodules with solitary calcification were detected.Thirty-...
