This was tested in people. That is the most reliable kind of research we share.
This looked at scan pictures in people, and it is not a treatment.
The short version
Which brain scan shows a spot best may depend on what the spot is made of.
What was studied. Doctors scanned 27 adults whose melanoma had spread to the brain. They compared two kinds of MRI scans on 261 brain spots, sorted by what each spot was made of.
What they found. Spots with dark pigment showed up better on the GRE scan. About 70.3% of them looked clearer that way. Spots without pigment, and spots with bleeding, showed up better on the black blood scan. That was true for 60.6% and 61.5% of them.
What this means, and what it doesn't
What it could mean: There may be no single best scan for these spots. Using both scans may help doctors see more of them. Your care team decides which scans to use for you.
What it doesn't mean: This is not a treatment, and it is not a cure. It was one small study at one hospital. The doctors say more studies are needed. They do not yet know if using both scans finds more spots or changes care.
