Whole-body MRI: what it can and cannot do

2 min read · 2 sources · reviewed October 2026

In short

Some private clinics sell whole-body MRI scans to people who have no symptoms. The American College of Radiology, as reported by the RSNA, and Health Canada both say the evidence does not support recommending these scans for people without symptoms. Downsides raised include further tests, findings that may not matter, and cost and access. This page does not tell you whether to have a scan.

Some private clinics sell whole-body MRI scans to people who have no symptoms. This page summarises what two sources say about that use. It does not tell you whether to have a scan.

What professional bodies say

According to a July 2026 news article from the Radiological Society of North America, the American College of Radiology said in 2023 that there is insufficient evidence to recommend total-body screening for people without symptoms.1 The article also says it is not yet known whether finding more cancers this way helps people live longer.1

Health Canada's page on whole-body screening says there is no scientific evidence to recommend these scans for people without symptoms.2 The page was first published in 2003 and last updated in 2023.2

Downsides raised

  • Further tests. The RSNA article cites studies suggesting more than 60% of patients go on to have more imaging, and says follow-up can include biopsies and surgery, which carry their own risks.1
  • Findings that may not matter. Health Canada's page says suspicious findings often lead to further tests or procedures that may be unnecessary, and that a normal result can give false reassurance.2
  • Cost and access. The RSNA article notes that self-pay access may favour higher-income patients.1

Where scans are used

This page covers scans for people without symptoms. People who have symptoms, or a known medical reason for imaging, are in a different situation. A health professional can say what applies to you.

What this means for comparing prices

The listings on this site show what clinics charge. They do not mean a scan is right for you. If you are comparing, check what the scan covers, whether a radiologist report is included, and what the clinic does if the scan finds something that needs follow-up.
