All the x-ray pictures are combined to make one
detailed picture of the body part. This type of scan is
very good at showing kidney tumors.
A CT scan of your belly area (abdomen) and pelvis
is recommended to check if there is a tumor in either
of your kidneys. The pictures can clearly show the
tumor size, shape, and location. This test can also
show if the tumor has grown into nearby tissues.
Before the CT scan, you may be given a contrast dye
to make the pictures clearer. The dye may be put in
a glass of water for you to drink, or it may be injected
into your vein. It may cause you to feel flushed or
get hives. Rarely, serious allergic reactions occur.
Tell your doctors if you have had bad reactions in the
past. The contrast dye might not be used if you have
a serious allergy or if your kidneys aren’t working
A CT scan machine is large and has a tunnel in the
. During the scan, you will
need to lie face up on a table that moves through the
tunnel. The scanner will rotate an x-ray beam around
you to take pictures from many angles. You may hear
buzzing, clicking, or whirring sounds during this time.
One x-ray scan is completed in about 30 seconds.
But, the full exam may take 15 to 60 minutes
to complete. More or less time may be needed
depending on the part of your body being scanned.
A computer will combine all the x-ray pictures into
one detailed picture. You may not learn of the results
for a few days since a radiologist needs to see the
pictures. A radiologist is a doctor who’s an expert in
reading the pictures from imaging tests.
