Overview

Computed tomography can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive. The findings on CT scan may include large main pulmonary artery, ventricular septal defect, and right ventricular hypertrophy.

CT scan

Computed tomography can be used as a diagnostic modality in congenital heart diseases.

Advantages

• Provides additional anatomic details compared to echocardiography
• It is done faster compared to MRI, thus avoiding the need for anesthesia in children.

Disadvantages

• Costly
• Radiation can have long terms side-effect on growing children.

Findings

The findings of CT scan examination in Eisenmenger's syndrome include :

• Large main pulmonary artery
• Ventricular septal defect
• Right ventricular hypertrophy
• Pulmonary neovascularity
• Pulmonary artery calcification.
