亚急性甲状腺炎超声、核素扫描的临床意义

目的　评价超声、核素影像学在亚急性甲状腺炎诊断中的作用。方法　回顾性分析了经病理或临床明确诊断为亚甲炎47例患者的超声、核素影像表现及特点。结果　47例中，Ⅰ、Ⅱ型37例，超声特征33例为片状低回声，5例为回声不均质性增强，并点片状低回声灶，正确诊断率为91.9%（34/37）。核素扫描为甲状腺不显影或显影不清，正确诊断率为81.1%(30/37)。两种结果有较好一致性（χ

Clinic Signification of Ultrasonography and Scintigraphy in the Subacute Thyroiditis

Objective 　To evaluation the diagnostic value of ultrasonography and scintigraphy in the subacute thyroiditis. Methods　47 patients with subacute thyroiditis diagnosed pathology or clinic retrospectively were analyzed their ultrosonographic and scintigraphic manifest and characteristics. According to thyroid clinical characteristic, the cases were classified. Results 　In 47cases, Ⅰ and Ⅱ have 37, of 33 are hypoechogenicity in ultrosonogrphic characteristics.5 is asymmetric hyperecho with small focal hypoecho. The right diagnose rate is 91.9%(34/37). Thyroid gland is not develop or underdeveloped by scintgraphy. The accurate diagnose rate is 81.1%(30/37). These two results have preferably coherence (χ2=22.97,P<0.001). Ⅲ have 7cases.Thyroid gland ultrosonography show irregularly and nodal enlargement. Right diagnose rate is 71%(5/7). Thyroid gland scintgraphy appears cold nodal with setting thickly or irregular throughout. Conclusions 　Both of ultrasonography and scintigraphy have specificity. In Ⅰ and Ⅱ,two examined results have preferably coherence. In Ⅲ, ultrasonography need to differentiate with tumor, and scintigraphy is not specific.
