The scan covers all major organs and systems from the head to the upper-thigh, which is where the most significant health findings occur. This includes the brain, spine, chest, heart, major vessels, abdomen, and pelvis across six distinct scan areas. Arms and legs below the upper-thigh are not included. The OneMRI scan is designed to look at internal organs and structures. There is considerably less clinical value in preventative imaging in the arms and below the pelvis, and scanning the full legs would add time and cost without meaningfully improving the health picture. The scan captures what matters most for a preventative health baseline.

The six areas reflect the way the radiologist reviews and reports findings, not six separate scans. Everything is captured in a single 60-minute session. Breaking the scan into areas makes it easier to understand what is covered in each region and what the radiologist is specifically looking at.

Each area covers structures that are genuinely worth understanding. The abdomen and pelvis covers more organs than any other single region. The blood vessels and circulation are among the most significant given how silently vascular changes can develop. The spine and joints are the areas most people have a direct relationship with through everyday movement and discomfort.

The scan covers all six areas as a complete package. Individual areas cannot be selected or removed. The value of the full-body scan is in seeing everything together, because some findings only become meaningful when viewed in the context of the whole picture.
