Abstract：Objective: To find the best imaging examinations for conjoined twins by reviewing the previous cases. Methods: The imaging exams from the six previous cases were analyzed retrospectively, and the results were compared in relation to pathology and operative result. Results: There were five pairs of thoraco-omphalopagus conjoined twins among the six cases, and the other pair was ischiopagus. The five thoraco-omphalopagus cases all had conjoined livers and portions of the chest bones fused. All the patients of the six cases had different kinds of congenital heart disease. The ischiopagus conjoined twins had the common rectum. The operation results match with the imaging diagnosis. Conclusion: The inside abnormality of conjoined twins can be better understood by using suitable imaging exams, which has important significance for the evaluation of the operation and the overall prognosis.
