What are the risks of a CT abdominal scan for a child? A CT scan uses radiation. Repeated exposure to radiation raises a person’s risk for cancer in the future.
The first study to assess directly the risk of cancer after CT scans in childhood found a clear dose-response relationship for both leukemia and brain tumors: risk increased with increasing cumulative radiation dose.
The level of risk associated with a CT scan is not only related to the level of radiation dose, but also to the child’s age and gender. In general risks are lower the older you are. Responding to radiation risk The CT scan settings can be adapted for children (i.e. “child-sized”) to obtain the necessary information with
They reported that the estimated lifetime cancer mortality risks attributable to the radiation exposure from a CT examination of a one year old are 1 in 550 for a single abdominal CT, and one in 1500 for a head CT.
direct risk to one child. This information shows that the risk of developing cancer related to a single CT scan is very small, but the available research indicates that there may be some risk and the risk may be cumulative. How can we minimize radiation risk to my child? There are ways to ensure that your child is exposed to the
1 Ιουλ 2013 · To develop diagnostic reference ranges (DRRs) and a method for an individual practice to calculate site-specific reference doses for computed tomographic (CT) scans of the abdomen or abdomen and pelvis in children on the basis of body width (BW).
What are the risks of a CT abdominal scan for a child? A CT scan uses radiation. Repeated exposure to radiation raises a person’s risk for cancer in the future. The CT scan should be done with the lowest possible radiation dose needed for the images to diagnose your child's problem.
