Computed tomographic angiography uses CT scanner to obtain specific diagnostic information that cannot be provided by or is complementary to other imaging technologies such as echocardiogram or cardiac catheterisation e.g abnormal blood vessel in the lung.
A contrast (dye) will be injected via a peripheral vein on your hand or arm. The scan will delineate the structures inside and outside the heart.
The procedure will take about 10 – 30 minutes. If your child is anxious and not able to follow instruction, medication to sedate your child is given orally or via injection. This helps your child sleep during the procedure.
