Overview[edit | edit source]

Computed tomography can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive.

CT[edit | edit source]

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

Advantages[edit | edit source]

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

Disadvantage[edit | edit source]

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

Recommendation for Cardiac Computed Tomography[edit | edit source]

The accompanying ionizing radiation exposure is the primary drawback of cardiac computed tomography as an imaging technology (including CT angiography). This is especially problematic for ACHD patients for whom lifetime serial examinations are planned. At the expense of a greater radiation dose, gating CCT to the ECG enables image acquisition during several phases of the cardiac cycle, enabling cine imaging and the choice of specific cycle periods of interest (often end-systole and end-diastole).
