Abstract: 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.
