摘　　要：目的观察多层螺旋CT应用于肺磨玻璃结节诊断中的价值及分析CT指标。方法选择2023年1—12月济宁市第三人民医院收治的57例肺磨玻璃结节患者,进行多层螺旋CT检查、病理学检查,将病理学检查作为“金标准”,观察多层螺旋CT应用于肺磨玻璃结节定性诊断中的效果。根据病理学检查结果分为恶性组、良性组,比较2组CT指标,分析相关CT指标。结果病理学检查结果证实,57例肺磨玻璃结节患者中,25例(43.86%)为恶性,32例(56.14%)为良性;以病理学检查结果作为“金标准”,多层螺旋CT应用于肺磨玻璃结节定性诊断中的敏感度、特异度、准确度、阴性预测值、阳性预测值分别为92.00%(23/25)、96.88%(31/32)、94.74%(54/57)、93.94%(31/33)、95.83%(23/24),与病理学检查结果的一致性Kappa值为0.893。恶性组病灶边界模糊、内部结构不均匀、空泡征、分叶征、毛刺征占比分别为80.00%、84.00%、44.00%、64.00%、56.00%,均高于良性组的37.50%、34.38%、0、9.38%、9.38%;恶性组最大直径、CT值分别为(11.97±1.81)mm、(-387.43±121.30)HU,均高于良性组的(7.27±1.02)mm、(-510.31±160.03)HU,差异有统计学意义(P<0.05)。结论多层螺旋CT应用于肺磨玻璃结节定性诊断中的效果较好,相关CT指标包括病灶边界、内部结构、空泡征、分叶征、毛刺征及最大直径、CT值,可为临床医生提供更可靠的影像学依据。Objective To observe the value of multi-slice spiral CT application in the qualitative diagnosis of pulmonary ground glass nodules and the analysis of CT index.Methods A total of 57 patients with pulmonary abraded glass nodules in Jining Third People's Hospital from January to December 2023 were selected for multi-slice spiral CT examination and pathology examination,and pathology examination was taken as the"gold standard"to observe the effect of multi-slice spiral CT in the qualitative diagnosis of pulmonary ground glass nodules.According to the pathological examination results,the two groups were divided into malignant group and benign group.The CT indexes of the two groups were compared and the relevant CT indexes were analyzed.Results The pathological examination results confirmed that among the 57 patients with pulmonary ground glass nodules,25 cases(43.86%)were malignant and 32 cases(56.14%)were benign.Using pathological examination results as the"gold standard",the sensitivity,specificity,accuracy,negative predictive value,and positive predictive value of multi-slice spiral CT in qualitative diagnosis of pulmonary ground glass nodules were 92.00%(23/25),96.88%(31/32),94.74%(54/57),93.94%(31/33),and 95.83%(23/24),respectively.The Kappa value of consistency with pathological examination results was 0.893.The percentages of blurred boundary,uneven internal structure,vacuole sign,lobulation sign and spicule sign in malignant group were 80.00%,84.00%,44.00%,64.00%and 56.00%,respectively,which were higher than 37.50%,34.38%,0,9.38%and 9.38%in benign group,the maximum diameter and CT values of the malignant group were(11.97±1.81)mm and(-387.43±121.30)HU,respectively,which were higher than(7.27±1.02)mm and(-510.31±160.03)HU of the benign group,and the differences were statistically significant(P<0.05).Conclusion The application of multi-slice spiral CT in the qualitative diagnosis of pulmonary ground glass nodules is good.The relevant CT indicators include lesion boundary,internal structure,vacuole sign,lobul
