Diagnostic Value of CT Enhanced Scanning Combined with Post-processing Technology on Benign and Malignant Thyroid Lesions
Objective To observe the diagnostic value of CT enhanced scanning combined with post-processing technology on benign and malignant thyroid lesions.Methods 134 patients with thyroid nodules confirmed by pathology in the hospital were selected from September 2018 to September 2022 as the study subjects.All patients received CT enhanced scanning combined with post-processing technology,and the value of this technology in diagnosing benign and malignant thyroid nodules was explored.The image features,CT value in plain scan phase,CT value in arterial phase,and CT value in venous phase were compared among the patients,and the lesion calcification was paid attention to.Results Among 134 patients with thyroid nodules,74 cases were malignant and 60 cases were benign by pathological examination,and 76 cases were malignant and 58 cases were benign by dual-phase enhanced spiral CT scanning.The sensitivity,specificity and accuracy rate of dual-phase enhanced spiral CT scanning in the diagnosis of benign and malignant thyroid nodules were 97.30％,93.33％and 95.52％by using pathological examination as the gold standard.The proportions of irregular shape,blurred boundary and enlarged lymph nodes in malignant group were significantly higher than those in benign group(P＜0.05).There were no statistically significant differences in CT value in plain scan phase,CT value in arterial phase and CT value in venous phase between the two groups(P＞0.05).The proportion of calcification point in malignant group was significantly higher than that in benign group(P＜0.05).Conclusion Spiral CT enhanced scanning and post-processing technology are of great significance in the differential diagnosis of benign and malignant thyroid nodules,and the image features and calcification characteristics are more obvious,which can provide important basis for clinical diagnosis and treatment.
