In any clinical trial, there are risks and benefits to consider when deciding
whether or not to participate. To learn more about risks and benefits of
clinical trials, go to Should I Take Part in a Clinical Trial?
Some factors that are specific to imaging trials you may wish to consider are:
-
Some imaging procedures may be uncomfortable, such as lying for a period of
time in a magnetic resonance or CT scanner.
-
If two imaging techniques are being compared and you receive both, you might be
subject to more X-rays or radioactive substances than if you did not
participate in the trial. Having more than one test will take extra time
although frequently there is added benefit from both tests.
-
Some studies may require injection of contrast agents that increase the ability
of an imaging technique to tell the differences between tumors and normal
cells. Injection of these agents may require an injection into a vein for
access to the blood stream (an I.V.). The contrast agents could cause
discomfort, or in rare instances an allergic reaction may occur.
-
Most trials cover the cost of the imaging procedures but in some circumstances
health insurance may be relied upon. Your coverage may not include some or all
of these costs. For more information on dealing with cost and coverage
barriers, see the description of the specific trial as well as

and Insurance Coverage: A Resource Guide.
