目的：评价磁共振快速反转恢复序列(TIRM)和多 b 值 DWI 序列在肺结节的良恶性鉴别诊断中的价值。方法采用3.0T MR 对30例 CT 平扫所见肺部结节的患者进行扫描,包括 T1 WI、T2 WI、TIRM 及 DWI,测量表观扩散系数(ADCtot)值。结果在鉴别肺结节良恶性方面,常规 MR 结合 TIRM 序列较 CT 平扫有相同的诊断效率。分叶征在良恶性结节具有显著统计学差异(P <0.005),胸膜凹陷征及 ADCtot 值在良恶性结节具有显著性差异(P <0.05)。结论磁共振 TIRM 和多 b 值 DWI 序列成像对鉴别肺结节的良恶性有一定的价值。

Objective To evaluate the value of turbo inversion recovery magnitude(TIRM)and multi-b values diffusion weighted i-magine(DWI)in differential diagnosis of benign and malignant pulmonary nodules.Methods 30 patients with pulmonary nodules confirmed by non-enhanced CT scans underwent 3.0T MR imaging including T1 WI,T2 WI,TIRM and DWI sequences.The appar-ent diffusion coefficient (ADC)values were measured.Results There was the same diagnosis efficiency between the combination of routine MR with TIRM sequences and non-enhanced CT scan in differential diagnosis of benign and malignant pulmonary nodules. The difference of sublobe sign was statistically significant in differential diagnosis of benign and malignant nodules (P <0.005),the difference of pleural indentation sign and ADCtot were statistically significant in differential diagnosis of benign and malignant nod-ules (P <0.05).Conclusion MR TIRM and multi-b values DWI sequences have the value in differential diagnosis of benign and ma-lignant nodules.
