What To Think About
- A gallium scan is used for specific types of
cancers, mainly of the
lymph nodes, bones, or
bone marrow. A normal scan does not exclude the
possibility of cancer, because some types of cancer do not show up on a gallium
scan. A gallium scan also cannot determine whether a tumor is cancerous
(malignant) or noncancerous (benign).
- The results of a gallium scan
should be interpreted along with the results of other tests, such as a physical
exam, blood tests, and X-rays. In many cases, results obtained from a
magnetic resonance imaging (MRI) or positron emission tomography (PET) scan may be as accurate as the results obtained from a gallium
scan. For more information, see the topics
Magnetic Resonance Imaging (MRI) and
Positron Emission Tomography (PET).
other nuclear scanning tests need to be done, these tests should be scheduled
before a gallium scan because the gallium tracer stays in the body longer than
other tracer compounds.
