[Abstract] Objective: To study MRI features and evaluate MRI values of retinoblastoma (RB) eyes which were identified by pathology.Materials and Methods: Total fourty-seven cases (male 30, female 12, ratio about 2:1) were included in the research. The ages ranged from 3 months to 8 years old, median was 2 years . All the MRI images were analyzed to evaluate the location, shape, signal and enhanced features of the masses.Results: Total 64 abnormal eyes were detected, bileteral eyes in 17 cases and unilateral eyes in 30 cases (the left and right eyes were equal). 35 masses in 24 eyes were spherical or ovale, lobulated 3 eyes 3 masses and irregular shaped 35 masses in 35 eyes. Single masses were found in 53 eyes, two masses in 7 eyes and three masses in 2 eyes. Calcification were found in 47 eyes, the signal is heterogeneous. Slight enhancement were seen in 7 eyes, mild enhancement in 31 eyes and marked enhancement in 2 eyes.Conclusion: MRI can clearly show the location, shape, number, signal and enhanced feature of RB masses. Furthermore MRI images can show masses outside eyes and the matastasis to brain.
