摘要
目的观察超声联合计算机断层扫描(CT)诊断甲状腺钙化结节的应用价值。方法收集2018年1月至2021年1月本院诊治的168例甲状腺结节患者的临床资料,所有患者均行超声与CT检查,以病检结果为“金标准”,分析超声诊断的影像学特征,对比单纯超声与超声联合CT诊断甲状腺钙化结节及良性钙化结节的效能。结果超声联合CT诊断钙化结节的特异度和阳性预测值与单纯超声比较无明显差异(P>0.05);超声联合CT诊断钙化结节的敏感度为87.18%、阴性预测值为83.33%、准确率为85.10%,明显高于单纯超声的敏感度、阴性预测值和准确率(P<0.05);超声联合CT与单纯超声对环形钙化及粗大钙化的检出率无统计学差异(P>0.05);超声联合CT诊断恶性钙化的敏感度、特异度、准确率、阳性预测值、阴性预测值分别为95.65%、92.00%、94.87%、97.78%、85.19%,明显优于单纯超声的诊断效能(P<0.05)。结论利用超声联合CT诊断甲状腺钙化结节,诊断效能更优,可有效鉴别钙化结节的良、恶性质,可指导临床诊治。
Objective To observe the application value of ultrasound combined with computed tomography(CT)in the diagnosis of thyroid calcified nodules.Methods The clinical data of 168 patients with thyroid nodules diagnosed and treated in the hospital were collected between January 2018 and January 2021.All patients underwent ultrasound and CT examination.The pathological results were taken as the gold standard to analyze the imaging characteristics of ultrasound diagnosis and compare the efficiency of ultrasound and ultrasound combined with CT in the diagnosis of thyroid calcified nodules and benign calcified nodules.Results There were no significant differences in specificity and positive predictive value of ultrasound combined with CT in the diagnosis of calcified nodules compared with those of ultrasound alone(P>0.05).The sensitivity,negative predictive value and accuracy rate were 87.18%,83.33%and 85.10%of ultrasound combined with CT in diagnosing calcified nodules,which were significantly higher than those in ultrasound alone(P<0.05).There were no statistical differences in detection rates of circular calcification and gross calcification of ultrasound combined with CT compared to ultrasound alone(P>0.05).The sensitivity,specificity,accuracy rate,positive predictive value and negative predictive value of the diagnosis of malignant calcification were 95.65%,92.00%,94.87%,97.78%and 85.19%of ultrasound combined with CT,which were significantly better than those of ultrasound alone(P<0.05).Conclusion The application of ultrasound combined with CT has better diagnostic efficiency in diagnosing thyroid calcified nodules,and can effectively distinguish the benign and malignant calcified nodules and can guide the clinical diagnosis and treatment.
