What risks are there from the test?
- The dye used in the test can affect your kidneys, and sometimes
they do not work as well after exposure to this dye. This effect
is almost always temporary, but some people can have permanent
damage. There is also a small chance of having an allergic reaction
to the x-ray dye used in the test.
As with all x-rays, there is a small exposure to radiation. In
large amounts, exposure to radiation can cause cancers or (in
pregnant women) birth defects. The amount of radiation from x-ray
tests is very small-too small to be likely to cause any harm.
X-rays such as this kind in the pelvis area should be avoided
in pregnant women, because the developing fetus is more sensitive
to the risks from radiation.
