Medical Screening and MRI
In a medical era governed by managed health care and scientific advances, physicians have increasingly emphasized disease prevention and early diagnosis. Such a strategy both reduces costs, as it is generally much more cost-effective to prevent a disease than it is to treat its manifestations, and increases treatment efficacy, as most diseases are more easily cured or ameliorated earlier in their progression.
The premise is doing MRI scans BEFORE symptoms arise. MRI is being offered to the public for as low as $200.
The pros and cons are discussed in an article entitled Brain Magnetic Resonance Imaging Scans for Asymptomatic Patients: Role in Medical Screening.
