摘要
目的探究分析甲状腺疾病的临床诊断中16排螺旋CT的价值,提高临床对该病的鉴别。方法选择该院2012年10月—2016年3月收治的70例经手术病理、实验室病理组织检查确诊为甲状腺疾病患者为研究对象,使用16排螺旋CT机对患者进行扫描,增强扫描时以3 m L/s的流量经肘部正中静脉注射对比剂碘海醇80 m L,并在注射完成后28 s和50 s进行扫描;扫描范围:从鼻唇沟由上往下逐渐扫描至胸廓入口平面,必要时加扫至充分显示结果。观察对比两组患者的诊断准确率。结果 16排螺旋CT对结节性甲状腺肿、甲状腺腺瘤、甲状腺癌及结节性甲状腺肿合并腺瘤的检出率分别为82.6%、100.0%、88.2%、85.7%,对甲状腺疾病诊断总符合率达91.4%,对单双侧甲状腺病变诊断符合率达95.7%,其中单侧病变符合率达94.6%(35例),双侧病变符合率达93.9%(31例)。结论甲状腺形态、大小及密度能通过CT扫描清晰显示出来,当甲状腺组织发生病变时可导致组织含碘量降低,CT图像上显示为低密度,故甲状腺病变可通过CT有效检出。16排螺旋CT能给临床提供清晰影像学资料,客观反映了病变组织与正常组织结构的关系,对甲状腺疾病的诊断符合率较高,尤其是甲状腺腺瘤,通过正确使用16排螺旋CT,可有效诊断甲状腺疾病并能避免误诊漏诊,给临床治疗引领方向。
Objective To study and analyze the value of 16-slice spiral ct in diagnosis of thyroid gland diseases and improve the differential diagnosis of the disease in clinic. Methods 70 cases of patients with thyroid gland diseases confirmed by the operative pathology and laboratory pathological tissue examination from October 2012 to March 2016 were selected and scanned by the-slice spiral ct, and the patients were given the intravenous injection of 80ml contrast media iohexol through the median elbow at the rate of 3ml/s and scan was conducted in 28s and 50s after injection, and the scan range was from nasolabial groove gradually to thoracic entrance plane, if necessary, the scan was en-hanced, and the diagnosis accuracy of the two groups was observed and compared. Results The test rates of nodular goiter, thyroid adenoma, thyroid carcinoma and nodular goiter combined with adenoma by the 16-slice spiral ct were respectively 82.6%, 100.0%, 88.2%, 85.7%, and the total diagnosis coincidence rate of thyroid gland diseases reached 91.4%, and the diagnosis coincidence rate of unilateral and bilateral thyroid gland diseases reached 95.7%, and the co-incidence rate of unilateral and bilateral lesions respectively 94.6% （35 cases ） and 93.9% （31 cases）. Conclusion The thyroid morphology, size and density can be clearly showed by the CT scan, the tissue iodine amount decreases when the thyroid gland tissues are diseased, which is shown the low density, objectively reflecting the correlation between le-sion tissues and normal tissue structure, and the diagnosis coincidence rate of thyroid gland diseases is higher, especial-ly the for the thyroid adenoma, and the accurate use of 16-slice spiral ct can effectively diagnose the thyroid gland dis-eases and avoid the missed diagnosis and misdiagnosis, which can guide the clinical treatment.
