Abstract：Objective: To discuss the imaging characters of MSCT and MRI in hepatic multifocal nodular fatty infiltration. Methods: 10 cases of hepatic focal nodular fatty infiltration were diagnosed by histopathologic examination from January 2017 to March 2018. They were examined by plain and enhanced scan with MSCT and MRI, and retrospectively analyzed for the nodules number, location, size, density/signal, shape, degree and pattern of enhancement. Results: 8 cases were multiple nodules, and the other 2 showed isolated nodule. 10 cases of the lesions were low density in MSCT. All the lesions were with hyper-intensity on in-phase(IP) images and hypo-intensity on out-of-phase(OP) images. 1 case with isolated nodule showed a slightly hypo-intensity on T2-FS. All the lesions didn't show in other MRI sequences. The pattern of enhancement in MSCT and MRI showed the same way. The degree of enhancement of the lesions were lower than that of liver parenchyma, the curve of reinforcement of the lesions were the same as the liver parenchyma or slightly lower in portal and delayed scanning. Conclusion: MSCT and MRI imaging can clearly display the features of HMNFI, especially on the in-phase and out-of-phase images, which are helpful for accurate diagnosis.
