Full-Body MRIs Promise To Detect Disease Early. Do They Work?

The latest trend in celebrity health care is full-body MRI scans, with influencers like Kim Kardashian endorsing them. These scans aren’t covered by health insurance, and run over $2,000 out of pocket. Typically, a new diagnostic tool is marketed to doctors and radiologists. But companies like Prenuvo are now marketing directly to consumers. They claim that their scans will catch early signs of cancer, aneurysms, liver diseases and even multiple sclerosis.It’s an appealing promise. If you can afford it, wouldn’t it be nice to catch cancer super early? Could it even save your life? Unfortunately, it’s more complicated than that. Simply put, the potential harms far outweigh any possible benefits of such a scan. Guest host Flora Lichtman separates fact from fad with Dr. Rebecca Smith-Bindman, professor of epidemiology and biostatistics at University of California, San Francisco’s School of Medicine, and director of the Radiology Outcomes Research Laboratory, based in San Francisco, California. To stay updated on all-things-science, sign up for Science Friday's newsletters. Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
