Frequent question: Can an MRI detect metastatic cancer?


Can MRI detect cancer metastasis?

Using MRI, doctors can sometimes tell if a tumor is or isn’t cancer. MRI can also be used to look for signs that cancer may have metastasized (spread) from where it started to another part of the body. MRI images can also help doctors plan treatment such as surgery or radiation therapy.

Can MRI Miss bone Mets?

MRIs can also show any small bone tumors several inches away from the main tumor (called skip metastases). Knowing the extent of tumor is very important when planning surgery.

Can a CT scan show metastasis?

CTs are incredibly useful for diagnosing and staging cancer, checking whether it has come back, and monitoring whether a treatment is working. It’s very effective for surveying the entire body to look for places where the cancer has spread, such as the lungs, liver, or bone. These are called metastases.

How fast does aggressive cancer grow?

How do you detect metastasis?

Metastasis — which accounts for 90% of cancer-related deaths1, and occurs when cancer cells detach from their primary site and home in distant organs — can be detected through non-invasive clinical-imaging modalities such as magnetic resonance imaging (MRI), X-ray computed tomography (CT) and positron emission
