Considerations And Precautions For CT Scans In Pediatric Patients


Computed tomography (CT) scans use X-rays and computer processing to create detailed images of the internal components of the body, making it a valuable diagnostic technique. These scans provide vital information to physicians that expedite the diagnosis and treatment of several medical conditions. While CT scans are generally safe for adults, they can pose a risk to pediatric patients. It is due to the increased sensitivity of developing organs to ionizing radiation in children. The considerations and safety measures needed for administering CT scans to children will be covered in this article.

Risks Of CT Scans In Pediatric Patients

CT scans result in exposure to ionizing radiation which can lead to an increase in the risk of cancer and other radiation-induced health problems. Children are comparatively more vulnerable to the effects of ionizing radiation. It is due to their organs and tissues being in the developmental stage. The risk of radiation-induced cancer is highest in children who receive multiple CT scans over time. The American College of Radiology (ACR) recommends only doing these when the benefits outweigh the risks. It is especially true for pediatric patients.

Considerations And Precautions For CT Scans In Pediatric Patients


The first consideration in performing CT scans in pediatric patients is to ensure the scan is justified. The referring doctor must assess the patient to decide whether it is necessary for a diagnosis or course of therapy. To lessen the amount of ionizing radiation that the patient is exposed to, alternate imaging modalities should be used wherever possible. They include magnetic resonance imaging and ultrasonography (MRI).

Dose Reduction

The second consideration in performing CT scans in pediatric patients is the reduction in the radiation dose. The radiologists should adjust the dosage according to the weight and height of the patient. It also takes into consideration which body part is being imaged. Pediatric CT protocols with lower radiation doses in comparison to adults should be utilized whenever possible. The ACR recommends that this should be a standard operating procedure as it mitigates the risks considerably.

Image Quality

The third consideration in performing CT scans in pediatric patients is ensuring the image quality is adequate for diagnosis. Using low-dose protocols may result in lower image quality, which could affect the accuracy of the diagnosis. However, newer CT scanners produce high-quality images at lower radiation doses, reducing the risk of radiation-induced cancer in pediatric patients.


The fourth consideration in performing CT scans in pediatric patients is ensuring the patient remains stationary during the procedure. Children may not be able to remain still for the entire duration. Motion artifacts may appear as a result, which may reduce the precision of the diagnosis. Sedation or general anesthesia usage can keep the patient calm throughout the CT scan. Nonetheless, it is crucial to realize that both sedation and general anesthesia involve hazards. Medical professionals must carefully weigh the benefits against the potential risks before deciding to use them.

Patient Preparation

The fifth consideration in performing CT scans in pediatric patients is patient preparation. Children may be afraid or anxious about the scan, resulting in motion artifacts or the need for sedation. A child should be prepared in a way that is suitable for their age and level of comprehension. An explanation of the method and risks needs to be imparted to the parents or legal guardians as well.


The sixth consideration in performing CT scans in pediatric patients is follow-up. Children receiving CT scans need follow-ups to ensure they do not develop radiation-induced health problems. The parents or guardians should be fully aware of the scan’s benefits and drawbacks. They should inform them of any necessary follow-up care.

CT scans are a useful diagnostic tool that gives doctors crucial information for identifying and managing a wide range of medical disorders. Yet, CT scans might represent a concern to pediatric patients due to their higher sensitivity to ionizing radiation. As a result, it’s crucial to think about and use caution when performing CT scans on young patients. Justification for the scan, dose reduction, picture quality, sedation, patient preparation, and follow-up care are a few of these safety measures. These safety measures can help doctors perform CT scans on young patients safely and efficiently.

Other Considerations

During a CT scan, well-prepared parents or guardians are an integral part of the child’s safety. Inform them of the risks and benefits of the scan and encourage them to ask questions or voice any concerns. Parents or guardians can also help prepare their children for the scan. It is a neglected aspect of treatment that is instrumental in preventing issues before they arise.

Image Quality

Furthermore, using lower radiation doses during CT scans while preserving great image quality is now possible. For instance, newer CT scanners may modify the radiation dose in accordance with the patient’s weight and size. For pediatric patients, it means a lesser radiation dose. Additionally, iterative reconstruction algorithms can be utilized to improve image quality while reducing radiation exposure. The safety of CT scans in pediatric patients has significantly increased because of these technological developments.


When possible, use different imaging techniques to lessen the patient’s exposure to ionizing radiation. For example, ultrasound is a useful tool for evaluating the abdominal and pelvic region in pediatric patients. Radiologists, on the other hand, use MRIs to assess the brain and spinal cord. The requirement for CT scans will remain for specific diseases and conditions. In these cases, they must take precautions to ensure the patient’s safety.

Medical professionals also need to remember that children are not just smaller adults. During a CT scan, attend to their particular physical and emotional needs. Children may require a different kind of anesthesia than adults, for instance. Children may need more time to adapt to the scanning environment during CT scans. Therefore, medical personnel should be getting specialized training in pediatric radiology. It will mitigate the risks, and the process’s effectiveness will increase. To satisfy the patient’s needs, they should collaborate closely with pediatric specialists, including pediatric anesthesiologists.

Finally, it is important to emphasize the importance of communication and collaboration among medical professionals, parents, guardians, and pediatric patients. Medical professionals should explain the CT scan process and associated risks in a manner that is appropriate for the patient’s age and level of understanding. Encourage parents or guardians to be vocal with their queries and concerns. And remember to offer assurance and support throughout the process.


CT scans are a crucial diagnostic tool that can help identify and treat a variety of medical conditions. Yet, due to their sensitivity to ionizing radiation, radiologists must exercise caution while doing CT scans on children. But don’t worry we have got you covered, contact us now and avail the best diagnostic imaging services in the USA. To carry out CT scans on pediatric patients safely and effectively, physicians can take certain steps. The first is justifying the scan, followed by lowering the dose. They also need to retain image quality, administer sedation when necessary, prepare the kid correctly, and provide follow-up care.
