64排螺旋CT对甲状腺疾病的临床诊断价值

Clinical diagnostic value of 64-slice spiral CT for thyroid disease

目的探讨64排螺旋CT对甲状腺疾病的诊断价值,提高临床对甲状腺病变的认识。方法使用64排螺旋CT机进行扫描,行增强扫描时,选择对比剂优维显80 ml,高压注射器经肘部静脉团注,流速2 ml/s,注射后50 s进行扫描。扫描范围:从口咽部至胸廓入口水平,必要时加扫至充分显示肿块。结果回顾性分析滁州市第一人民医院166例经手术病理、实验室检查证实甲状腺疾病患者的CT诊断结果。64排螺旋CT对甲状腺肿、甲状腺炎、甲状腺肿瘤及甲状腺发育异常的诊断符合率分别为87.7%、90%、84.4%和100%,对甲状腺疾病的诊断符合率达87.8%。结论 CT能清晰显示甲状腺的形态、结构及密度。当甲状腺组织发生癌变或其它病变时,贮碘细胞被破坏,甲状腺组织中含碘量下降,CT图像上表现为低密度区,故CT是检查甲状腺病变的有效方法之一。64排螺旋CT可以为临床提供最直观的影像资料,更加客观地反映病变与周围组织结构的关系,诊断符合率也较高,特别是对甲状腺发育异常等疾病,正确应用64排螺旋CT检查,可以为甲状腺疾病的诊断及鉴别诊断提供依据,同时为临床的正确治疗指引方向。

Objective To explore the value of the 64-slice spiral CT in the diagnosis of thyroid disease and improve clinical understanding of it. Methods 64-slice spiral CT was used to scan the focuses. In enhanced scan,we choose contrast medium Ultravist 80 ml,inject intravenously through elbow by power injector at the speed of 2 ml / s,and scaned after 50 s injection. Scanning Scope： from the oropharynx to thoracic entrance level,scan to fully display the mass when necessary.Results CT diagnosis of 166 cases of thyroid diseases confirmed by operation pathology and laboratory tests in our hospital were retrospectively analyzed. The diagnosis accordance rate of 64-slice spiral CT for goiter,thyroiditis,thyroid tumor and abnormal development of thyroid was 87. 7%,90%,84. 4% and 100%,and for thyroid disease was 87. 8%. Conclusion CT can clearly show the morphology,structure and density of the thyroid. When the thyroid tissue becomes cancerous or diseased,iodine storage cells are destroyed,the iodine content in thyroid tissue declines,the CT image shows a low density area,so CT is one of effective ways to check thyroid lesions. The 64-slice spiral CT can provide the most intuitive image data for clinic,more objectively reflect the relationship between the lesions and surrounding tissues,get a higher diagnosis accordance rate,especially for thyroid d ysplasia and other diseases,correctly using the 64-slice spiral CT can provide the reference for the diagnosis and differential diagnosis of thyroid diseases,meanwhile,it can correctly guide the clinical treatment.
