Abstract: Objective:To explore the adult three real heart CT enhanced performance and operation pathology,improve the diagnostic level.Methods:A retrospective analysis of 3 cases were confirmed by operation and pathology of three real heart clinic data and CT manifestation.Results:three real heart imaging findings typical,common on the left side of the three branch real heart and on the right side of the three real(right atrial diverticulum).The complete three real hearts is left atria fiber membrane will be the one divides into two,with a hole in the middle.On the right side of the three housing is connected show with right atrial cystic structure,strengthen the concentric real,visible diverticulum mouth.Conclusion:spiral CT enhancement scanning and post processing technology in three real heart diagnosis significantly,can guide the clinical operation.
