An MRI isn’t going to modify your cardiac risk factors though.

Comparatively, MRI has terrible spatial resolution compared to CT and Radiography. So when looking for tiny things such as lung nodules, small pancreatic lesions, and small aneurysms you want the best spatial resolution. For example, we don't currently use MRI for lung cancer screening, we use CT which has much better detection for small lesions.

MRI is great contrast resolution (telling the difference between different tissues) for characterizing things and seeing the spread and extent of something initially seen other imaging modalities.

Furthermore, to acquire a whole-body MRI you have to crank up the field of view on the scanner which further degrades the spatial resolution of the scan. And forget about finding anything useful in anything that moves, the bowel, the lungs etc., or anything really small like small pancreatic lesions. Also, these companies aren't using contrast which lessens the sensitivity of the scans and they are relying on a concept called diffusion weighting to find these tumors. The problem is not all things that restrict diffusion are tumors and not all tumors restrict diffusion.
