| 目的 观察超短回波时间(UTE)-MRI评估肺结节的价值。方法 前瞻性对58例经CT检出的肺结节患者行UTE-MRI;以CT为参考,分析UTE-MRI评估肺结节直径、成分、肺部影像报告和数据系统(Lung-RADS)类型及影像学征象的价值。结果 CT共于58例中检出66个肺结节,直径(11.60±5.20)mm;包括实性结节29个、部分实性结节24个、磨玻璃结节13个,Lung-RADS 2类14个、3类12个、4A类12个、4B类11个及4X类17个;其中12个结节伴分叶征、14个伴毛刺征。UTE-MRI共检出63个肺结节,直径(11.34±4.82)mm;包括实性结节25个、部分实性结节28个、磨玻璃结节10个,Lung-RADS 2类12个、3类12个、4A类12个、4B类11个及4X类16个;其中10个结节伴分叶征、11个伴毛刺征。基于UTE-MRI与CT所测肺结节直径差异无统计学意义(P=0.803)且相关性和一致性均好(rs=0.953、ICC=0.946),二者评估肺结节成分及Lung-RADS类型的一致性均好(Kappa=0.871、0.960),对分叶征和毛刺征的显示率差异均无统计学意义(P均＞0.05)。结论 UTE-MRI可较好地评估肺结节,其效能与CT相当。 |

| Objective To observe the value of ultrashort echo time (UTE)-MRI for evaluating pulmonary nodules. Methods Totally 58 patients with pulmonary nodules detected with CT were prospectively enrolled, and UTE-MRI was performed. Taken CT as the referent standard, the value of UTE-MRI for evaluating the diameter, composition, lung imaging reporting and data system (Lung-RADS) type and radiographic signs of pulmonary nodules was analyzed. Results CT detected 66 pulmonary nodules with a diameter of (11.60±5.20) mm in 58 patients, including 29 solid nodules, 24 partially solid nodules and 13 ground-glass nodules. There were 14 Lung-RADS type 2, 12 type 3, 12 type 4A, 11 type 4B and 17 type 4X lung nodules, among which 12 were found with lobulated sign, and 14 were found with spiculated sign. UTE-MRI detected 63 nodules with a diameter of (11.34±4.82) mm, including 25 solid nodules, 28 partially solid nodules and 10 ground-glass nodules. There were 12 Lung-RADS type 2, 12 type 3, 12 type 4A, 11 type 4B and 16 type 4X lung nodules. Among which 10 nodules were found with lobulated sign and 11 were found with spiculated sign. No significant difference of the measured diameters of lung nodules was found between UTE-MRI and CT (P=0.803), and the results of UTE-MRI and CT had good correlation and consistency (rs=0.953, ICC=0.946), which also had good consistency for assessing nodule composition and Lung-RADS type (Kappa=0.871, 0.960). Meanwhile, no significant difference of the display rates of lobulated nor spiculated signs was noticed between UTE-MRI and CT (both P＞0.05). Conclusion UTE-MRI was helpful for evaluating pulmonary nodules, with efficacy comparable to CT. |
