Computed tomography (CT) is an X-ray that produces more detailed images of structures in the body than a conventional X-ray can. Computed tomographic angiography uses CT technology and three-dimensional reconstruction to produce images similar to angiograms without the need for an invasive procedure.
Your child’s doctor may have requested a CT scan to obtain specific diagnostic information that is not provided by or is complementary to other imaging technologies such as echocardiogram or cardiac catheterisation.
The procedure will take about 10 – 30 minutes depending on the complexity of the study. Your child will require to lie still throughout the study. 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.
Patients need to be fasted at least 4 hours prior to the study.
Only children who requires sedation will need admission a day before to facilitate the preparation and will be discharged after the procedure once your child regain full consciousness.
A bigger and cooperative children may come as an outpatient.
Complications are very rare which include rashes, vomiting and contrast leak into the tissue. If it occurs, please inform the nurses or radiology staffs immediately.
The report of the study will be informed to you by your doctor after the study or during your next clinic visit.
