[摘要] 目的 探討高頻超聲聯(lián)合SPECT應用于甲狀腺癌診斷中的臨床價值。方法 方便選取2017年6月—2018年6月該院收治97例甲狀腺腫瘤患者作為研究對象，全部患者均進行高頻超聲檢查，并聯(lián)合SPECT檢查進行診斷，將術后病理學結果作為“金標準”，分析高頻超聲聯(lián)合SPECT應用于甲狀腺癌診斷中的臨床價值。結果 經手術及病理證實，97例患者中良性腫瘤51例，約占52.58%;惡性腫瘤46例，約占47.42%。高頻超聲聯(lián)合SPECT組檢出良性腫瘤50例、惡性腫瘤45例，診斷準確率為97.94%;高頻超聲組檢出良性腫瘤46例，惡性腫瘤42例，診斷準確率為90.72%。兩組比較差異有統(tǒng)計學意義（P<0.05）;高頻超聲聯(lián)合SPECT組無誤診情況發(fā)生，共2例漏診，漏診率2.06%;高頻超聲組1例誤診，誤診率1.03%，8例漏診，漏診率8.25%，差異有統(tǒng)計學意義（P<0.05）。結論 將高頻超聲、SPECT檢查聯(lián)合應用于甲狀腺癌診斷中具有重要臨床價值，可進一步提高診斷準確率，為疾病治療工作的開展及預后評估提供可靠影像學依據。

[Abstract] Objective To investigate the clinical value of high frequency ultrasound combined with SPECT in the diagnosis of thyroid cancer. Methods A total of 97 patients with thyroid cancer admitted to our hospital from June 2017 to June 2018 were convenient selected. All patients underwent high-frequency ultrasound examination and SPECT examination for diagnosis. The pathological results after operation were regarded as "gold standard". The clinical value of high-frequency ultrasound combined with SPECT in the diagnosis of thyroid cancer was analyzed. Results Surgery and pathology confirmed that 51 cases of benign tumors accounted for 52.58% and 46 cases of malignant tumors accounted for 47.42%. Fifty cases of benign tumors and 45 cases of malignant tumors were detected by high-frequency ultrasound combined with SPECT， the diagnostic accuracy was 97.94%. And 46 cases of benign tumors and 42 cases of malignant tumors were detected by high-frequency ultrasound combined with SPECT， the diagnostic accuracy was 90.72%. The difference between the two groups was statistically significant （P<0.05）. There was no misdiagnosis in the high frequency ultrasound combined with SPECT group， 2 cases were missed， the missed diagnosis rate was 2.06%. In the high frequency ultrasound group， 1 case was misdiagnosed， the misdiagnosis rate was 1.03%， 8 cases were missed， the missed diagnosis rate was 8.25%， the difference was statistically significant （P<0.05）. Conclusion The combination of high frequency ultrasound and SPECT has important clinical value in the diagnosis of thyroid cancer. It can further improve the diagnostic accuracy and provide reliable imaging basis for the development of disease treatment and prognosis evaluation.
