| 目的 探讨超声和CT对甲状腺肿块的诊断准确率。 方法 收集经手术病理证实的甲状腺肿块患者71例,其中良性者58例,恶性者13例。分析术前超声和CT表现,与手术病理所见的肿块边缘、钙化和囊变坏死状况对比,比较超声和CT的正确显示率。 结果 超声与CT显示甲状腺良、恶性肿块的数目、囊变坏死、形态、边缘、钙化和颈部肿大淋巴结方面差异均有统计学意义(P<0.05);超声显示良、恶性肿块的超声内部回声、晕环和CT平扫晕环征差异有统计学意义(P<0.05);与CT相比,超声可更清晰地显示甲状腺肿块的边缘(P<0.05),而对于钙化和囊变坏死的显示则与CT相似(P＞0.05)。 结论 超声和CT均能较好地显示甲状腺肿块,两者结合使用可提高诊断准确率。 |

| Objective To evaluate the diagnostic accuracy of ultrasonography (US) and CT for thyroid masses. Methods Seventy-one patients with thyroid masses (13 with malignant and 58 with benign tumors) confirmed by operation and pathology were collected. The apprearances of CT and US before operation were analyzed. The apperanecs of CT and US, including the clean edge of masses, calcification and cystic degeneration necrosis were compared with those of pathologic findings. Results The numbers, cystic changes, configuration, verge, calcify and enlarge cervical lymph nodes of thyroid lesions had statistical difference in CT and US (P<0.05). There was also difference in the internal echo, ring of halo on US and the sign of halo on plane CT (P<0.05). The edge of thyroid mass could be displayed more clearly with US than CT (P<0.05), however, it was similar with CT in the display of calcify and cystic changes (P<0.05). Conclusion Both CT and US can display thyroid mass clearly. Combing of CT and US could improve the accuracy rate of diagnosis. |
