Everyone who wants to take a proactive approach to their health.**
Early signs of cancer, fatty liver, aneurysms, and brain health decline often appear in places that lab tests alone may not be able to detect. Imaging can help.
Up until now, this type of MRI was prohibitively expensive to the vast majority of people. Function Scans make getting a full-body scan more accessible, affordable, and convenient. These start with the Full Body MRI, which takes just 22 minutes at a cost of $499.
**Certain individuals should not receive a Function Scan, namely those are: under 18; currently pregnant; living with certain metals in their body (e.g. pacemaker, prosthetic implant); subject to a recent cancer diagnosis; and/or undergoing active cancer treatment,.
A Function Scan is not included with Function membership. Function members have access to exclusive pricing for scans, but this cost is in addition to the cost of annual membership.
The Full Body MRI takes 22 minutes and is available to Function members for $499. If you’re looking for the most affordable, time-efficient way to get a comprehensive view of your body, this version is for you.
The Full Body MRI Plus takes 60 minutes and includes all Full Body MRI scans, as well as the spine. If you’re experiencing an ongoing problem like lower back pain, sciatica, or disc degeneration, this version can give you insight into herniated discs, spinal cord compression, or vertebral fractures.
The Full Body MRI Plus with CT includes all Full Body MRI Plus scans, as well as a lung and chest CT. This option is the right choice if you’re interested in screening for lung cancer and other thoracic concerns—especially if you’re at high risk for these issues due to smoking history.
The Full Body MRI Ultimate includes all Full Body MRI Plus with CT scans, as well as the hips and knees, plus AI-powered assessments for body composition, MS, dementia, brain age, aneurysms, and coronary plaque (CAC). If you want access to the most advanced imaging on the market (and don’t mind scheduling two separate 60-minute scans), this option is for you.
Unlike other types of scans, MRI produces no ionizing radiation. This means that the Full Body MRI and Full Body MRI Plus will not expose you to any harmful radiation.
A low-dose CT scan, or LDCT (included in the Full Body MRI Plus with CT and the Full Body MRI Ultimate) does involve ionizing radiation. Ezra’s LDCT protocol uses state-of-the-art machines and follows the American College of Radiology (ACR) guidelines to ensure that the dose is as low as reasonably achievable. This means that their LDCT delivers a radiation dose significantly lower than that of a conventional diagnostic chest CT.
