摘　　要：目的：探讨 MRI 在诊断胎儿先天性肺囊腺瘤样畸形（CCAM）中的价值。方法采用 MR 快速成像序列对8例超声（US）提示患先天性 CCAM 胎儿进行胸部横断面、矢状面及冠状面扫描,将产前 MRI 表现与出生后手术（2例）、引产尸检（3例）和CT（3例）结果对照。结果 MRI 诊断胎儿先天性 CCAM 7例,肺段隔离症（BPS）1例,均符合手术、尸检和 CT 结果。7例先天性CCAM,病变位于左肺 2例,右肺5例,囊肿型 2例、肿块型5例；BPS 1例,位于左肺下叶。结论 MR 快速成像技术可以清晰显示胎儿先天性 CCAM 的位置、类型和范围,是产前胎儿 US 检查的重要补充。Objective To explore the diagnostic value of MR fast imaging sequences in fetal lung congenital cystic adenomatoid malformation（CCAM）.Methods 8 cases with suspected CCAM by US were examined with MRI fast sequences,including single shot turbo spin echo （SSTSE）and balanced fast field echo（B-FFE）,and undergone axial,sagital and coronal scanning sections of fetal chests.MRI findings were compared with surgery（2 fetuses）,autopsy （3 fetuses）and CT examination （3 fetuses）.Results 7 fetuses with CCAM and 1 fetus with bronchopulmonary sequestration（BPS）diagnosed by MRI were confirmed by following surgery,autopsy and CT examination.Among the 7 CCAM cases,2 leisions were on the left side,while the other 5 lesions were on the right side.Fur-thermore,2 cases were cystic type and the rest 5 cases were mass type.The BPS was located in the lower left lung lobar.Conclusion MR fast imaging sequences in fetal can clearly demonstrate location,type and extent of CCAM and can provide important supplement information of the prenatal fetal ultrasound examination.
