多排螺旋CT和SPECT对亚急性甲状腺炎的诊断价值

目的:探讨多排螺旋CT和SPECT核素扫描对亚急性甲状腺炎的诊断价值。方法:经病理证实的100例亚急性甲状腺炎患者,对其多排螺旋CT和SPECT核素扫描影像资料进行回顾性分析,总结归纳其影像特点。结果:100例患者的多排螺旋CT平扫图像均可见甲状腺内斑片状边界模糊的低密度影,SPECT核素扫描见甲状腺显像浅淡且局部有放射性稀疏和缺损表现。SPECT所见稀疏和缺损区与CT图像显示的斑片状低密度影部位相一致,但范围较大。结论:SPECT核素扫描对亚急性甲状腺炎的诊断有重要的临床价值,CT显示甲状腺解剖结构较SPECT清晰,CT具有较高的密度分辨率,可以帮助排除其他疾病,对亚急性甲状腺炎的诊断和鉴别诊断有一定的价值。

Diagnostic Value of Multislice Spiral CT and SPECT in Diagnosis of Subacute Thyroiditis

Objective To investigate the diagnostic value of Multislice spiral CT and SPECT in diagnosis of subacute thyroiditis. Methods Multislice spiral CT and SPECT findings in 100 cases with subacute thyroiditis proved by pathology were respectively analyzed and summarized. Results Multislice spiral CT scan shows spotted low density focus with blurry edge in the thyroid. SPECT represents decrease of radioactivity, partial sparsity and absence of radioactivity. Multislice spiral CT scan was identical with SPECT finding, but range of focus in SPECT was showed larger than CT in displaying the abnormal image. Conclusion SPECT has important clinical value in diagnosis of subacute thyroiditis. CT can satisfactorily appear anatomical structure of thyroid because of its density resolving power. CT can help exclude other diseases in the diagnosis and differentiation of subacute thyroiditis1.
