A program called the Hercules Project is giving free whole-body MRI scans to people who can’t usually afford them, to see if cancer is found more often in poorer communities.

Descriptive

Doctors are testing if a full-body MRI scan can find hidden cancers sooner in people who feel fine, so they can start treatment faster.

Descriptive

Doctors are testing whether full-body MRI scans can reliably spot cancer by checking how often they correctly find it (and don’t miss it), using agreed-upon rules to interpret the images.

Descriptive

Using a full-body MRI scan on people who feel fine might help doctors find hidden cancers or other serious health problems early, especially when they use special rules to decide what needs follow-up.

Correlational

When doctors use two different scans to check for bone damage in multiple myeloma, they usually get the same results—but about 1 in 10 times, the MRI sees something the PET/CT scan misses.

Descriptive

For some people with an early form of blood cancer called smoldering myeloma, a special full-body scan (MRI) can spot hidden cancer cells in the bone marrow—even when there are no visible tumors—and this might help doctors decide to start treatment sooner.

Descriptive

A full-body MRI scan can find serious hidden health problems—like possible cancer or spinal issues—in people with certain types of blood cancer, even when a different scan called FDG-PET/CT misses them.

Descriptive

When doctors use both a full-body MRI and a special PET/CT scan together to check for multiple myeloma, they’re more likely to change the patient’s treatment plan than if they only use one scan alone.

Causal

A full-body MRI scan is better at spotting early signs of bone marrow cancer in certain types of myeloma than the PET/CT scan, especially when the cancer looks spread out in tiny spots — and this might change how doctors decide to treat patients.

Quantitative

Using a full-body MRI scan on people who feel fine can sometimes find hidden health problems they didn’t know they had—and some of those problems might need a doctor’s attention.

Descriptive

Using a full-body MRI scan on people who feel fine can find hidden health problems that doctors might need to treat—before those people start feeling sick.

Descriptive

When doctors scan healthy people’s whole bodies with MRI and find unexpected issues, most of those findings turn out to be important enough to check further—only about 1 in 10 are harmless.

Descriptive

When people who feel perfectly fine get a full-body MRI scan, doctors often find unexpected things like bumps or changes in their spine, belly, muscles, or organs — and this happens a lot, even when they have no symptoms.

Descriptive

Using a full-body MRI scan might help find cancers in body parts where doctors don’t normally screen people, like without a regular test.

Descriptive

When doctors scan the whole body with an MRI on people who feel perfectly fine and have no symptoms, they find cancer in about 1 in 64 of them.

Quantitative

Getting a full-body MRI scan to check for problems isn't worth the cost because it often finds harmless things that cause stress and tests, and no one has proven it helps people live longer.

Quantitative

Sometimes, a full-body MRI scan might miss a serious problem, making doctors think everything’s fine when it’s not — and that delay could lead to really bad health results.

Causal

No solid scientific studies have shown that getting a full-body MRI scan when you feel fine helps you live longer.

Descriptive

Some cancers found during routine screening might never hurt you — they grow so slowly that you’d die of something else before they ever became a problem.

Descriptive

Sometimes, when doctors do imaging scans like CT or MRI for one reason, they spot something unexpected. If they then do more tests or procedures because of that surprise finding, it can sometimes cause serious problems like bleeding, tissue harm, or nerve damage.

Causal

When healthy people without symptoms get a full-body MRI scan, about 1 in 3 people end up with some unexpected finding on the scan — and almost 6 out of 10 of those surprises don’t clearly mean anything medically important.

Descriptive

Finding and treating very slow-growing cancers through aggressive screening doesn’t help people live longer overall — it just finds cancers that wouldn’t have hurt them anyway.

Causal

Getting everyone screened for thyroid cancer finds a lot of harmless lumps that would never hurt you, so more people are told they have cancer—but it doesn’t save any lives.

Causal

Men and women are equally likely to have small, undetected thyroid cancer that doesn’t cause symptoms, no matter how old they are.
