摘要
目的 分析扩散加权成像(DWI)鉴别良、恶性孤立性肺结节(SPN)病变的可靠性。方法 收集本院2019年8月至2020年6月收治且经手术或病理确诊的54例SPN患者的临床资料,比较良、恶性SPN在不同b值中的信号强度、ADC值。结果 54例SPN患者恶性31例,良性23例。当b值=500s/mm^(2)时,良性SPN的ADC值显著高于恶性SPN(P<0.05)。b值=800~1000s/mm^(2)时,部分SPN在ADC图上无法测量ADC值,本组研究良性SPN中6例ADC值为0;恶性SPN中7例ADC值为0。DWI上良性SPN多呈等或略低信号,恶性SPN多呈高信号;b值为200~1000s/mm^(2)时,恶性SPN信号强度值均高于良性SPN(P<0.05)。结论 DWI的信号强度值与ADC值均可有效鉴别良、恶性SPN病变,其中信号强度值对良、恶性SPN评估效能更佳。
Objective To analyze the reliability of Diffusion Weighted Imaging(DWI) in distinguishing lesions of benign solitary pulmonary nodule from the lesions of malignant solitary pulmonary nodule(SPN). Methods The clinical data of 54 SPN patients who were admitted to our hospital from August 2019 to June 2020 and were diagnosed by surgery or pathology were collected. The signal intensity and ADC value in different b values between benign and malignant SPN were compared. Results In 54 SPN patients, 31patients were malignant and 23 patients were benign. When b value=500s/mm^(2), the ADC value of benign SPN was significantly higher than that of malignant SPN(P<0.05).When the value of b=800~1000s/mm^(2), ADC values of some SPNs cannot be measured on the ADC chart. Among the benign SPNs studied in this group, the ADC value of 6 cases was 0. Among malignant SPN, the ADC value of 7 cases was 0. On DWI, benign SPN mostly showed equal or slightly low signal, and malignant SPN mostly showed high signal. When the b value was 200~1000s/mm^(2), the signal intensity of malignant SPN was higher than that of benign SPN(P<0.05). Conclusion The signal intensity value of DWI and ADC value can effectively distinguish benign SPN lesions from malignant SPN lesions, and the signal intensity value is more effective in evaluating benign and malignant SPN.
