Abstract

Abstract: To discuss the distinguishing value of computed tomography (CT) and magnetic resonance imaging (MRI) for benign and malignant thyroid nodules, 150 patients with thyroid nodules were selected from March 2015 to March 2018 in our hospital. According to the pathological results, they were divided into 48 cases malignant and 102 cases benign, all patients were examined by CT and MRI. The distinguishing value of CT and MRI for benign and malignant thyroid nodules was analyzed. The total focus, irregular shape, unclear boundary/roughness, signal/density uneven detection rate in the MRI were significantly higher than those in the CT, the calcification detection rate in the MRI was significantly lower than that in the CT, the difference was statistically significant (P<0.05). The comparison of the lymph node metastasis detection rate in the CT and MRI, the difference was not statistically significant (P>0.05). In the sensitivity, specificity, accuracy of the distinguishing value for benign and malignant thyroid nodules, the CT were 79.17%, 74.51%, 76%, the MRI were 83.33%, 80.39%, 81.33%, the CT combined MRI were 95.83%, 96.08%, 96.00%, the CT combined MRI were significantly higher than the CT or the MRI, the difference was statistically significant (P<0.05). Conclusions:CT and MRI can be used as the important method for differentiating benign and malignant thyroid nodules, CT has the high resolution to calcification, MRI has the high resolution to soft tissue and small lesions, CT combined with MRI can effectively improve their distinguishing value.
