Whole-body MRI is one of the most debated tests in preventive health. Critics say it finds too much and proves too little, and the American College of Radiology doesn't recommend it for people without symptoms or risk factors. On a recent episode of NextLevel, our series on healthcare's shift from episodic to continuous, Dr. Daniel Durand makes the case for it anyway. Durand is chief medical officer of Prenuvo, one of the largest whole-body MRI providers. He's also a Johns Hopkins-trained radiologist who spent a decade working in value-based care. His argument hinges on something almost none of us have had while healthy: more than one scan.
