What Affects the Test
Reasons why the test results may
not be helpful include:
- Not being able to stay still and hold your
breath when asked during the test.
- Metal objects (such as spinal
fixation rods and metal jewelry or belts) that get in the way of the X-ray
- Obesity, which
can hide chest problems or make it hard to get a good X-ray
- Chest pain that can make it hard for you to take a deep
breath during the X-ray.
- Scarring from past lung surgery or changes
from a chronic disease, which may make the X-ray pictures hard to read.
A picture taken with a portable machine may not be as clear
as those made by a stationary machine.
What To Think About
- Your X-ray test results may be different from
earlier test results because you were tested at a different medical center or
you had a different kind of test.
- If a chest
X-ray is not normal, more specific X-rays or other tests such as a
MRI scan, or a
biopsy may be done.
- Some conditions may
not show up on a chest X-ray, such as a small cancer, a
pulmonary embolus, or other problem that is hidden by
the normal structures in the chest.
- Certain workers, such as people
who work with asbestos, may need regular chest X-rays to check for problems
caused by asbestos.
