Diagnosis of 320-row detector dynamic volume CT in complex congenital heart disease with double outlet right ventricle / 重庆医学

ABSTRACT

Objective To explore the diagnosis value of 320-row detector dynamic volume CT in complex congenital heart disease (CCHD)with double outlet right ventricle(DORV).Methods Seventy-eight patients who proveed DORV by surgery in Xinqiao Hospital of Third Military Medical University were reviewed.Thirty-six patients of group A performed 320-row detector dynamic volume CT by using segmental analysis,and were compared with the group B(42 Cases) performed conventional 64-slice CT respectively.Results In 36 cases of DORV confirmed by surgery in group A,MSCT provided accurate qualitative diagnosis in all cases.The accuracy rate of diagnosis of the group B was 90.7％.There was no significant differences compared with the group A (P＞0.05).There were ventricular septal defect in all the 78 cases,pulmonary stenosis in 56 cases,atrial septal defect in 34 cases,pulmonary hypertension in 21 cases,patent ductus arteriosus in 16 cases,coarctation of aorta in 9 cases.Conclusion The 320-row detector dynamic volume CT has important diagnostic value for DORV of the anatomical diagnosis.
