Abstract:Objective To analyse the Magnetic Resonance Imaging (MRI) manifestations of abnormal fetal liver, to explore the diagnostic value of MRI in fetal liver related lesions.Methods The fetal MRI image data of 19 cases with liver abnormalities in the First Affiliated Hospital of Sun Yat-sen University were retrospectively analysed from January 2010 to June 2014. The pregnant women were 22-35 years old, and the gestational ages were 25 to 38 weeks. The Fetal MRI was performed with horizontal and coronary axis T1, T2-weighted images, sagittal axis T2-weighted images.Results The fetal liver abnormal cases include diaphragmatic hernia in 8 cases (7 cases on the right side, left 1 case), diaphragmatic bentonite to rise in 1 case, acromphalus in 2 cases, hemangioma in 3 cases, hamartoma in 2 cases, fetal anemia in 3 cases. The pathological diagnosis after induced labor dead 4 cases, 14 cases of postpartum surgery pathological diagnosis, follow-up review confirmed in 1 case. According to the position of the liver and abnormality of signals, the abnormal fetal liver position 11 cases, among them, shift to the chest in 9 cases, translocation to the abdominal wall in 1 case. There were abnormal liver signal in 8 cases, including 5 cases with focal abnormal signal (both for liver tumors) characterized by abnormal intrahepatic type circular signal. Diffuse abnormal signal in 3 cases, including twins transfusion syndrome in 2 cases, the Mediterranean anemia in 1 case, are characterized by diffuse reduce liver T2WI signal. This group of MRI in the diagnosis of abnormal fetal liver position coincidence rate was 100%, and accurately determine insufflate adjacent structures such as the location of the change. MRI qualitative diagnosis of hemangioma was better.Conclusions Abnormal fetal liver involves a variety of diseases. MRI has its unique advantages in the diagnosis of abnormal fetal liver position, which is helpful to the diagnosis of fetal liver signal abnormalities, and helps to achieve a comprehensive diagnosis of fetal liver.
