Rely on the clinical history for diagnosis. Although diseases such as multiple sclerosis have a high detection rate on MRI, most diagnoses are arrived at clinically
Wherever there are electromagnetic fields (EMFs), there are potential problems for people with pacemakers. Magnetic resonance imaging (MRI) scans can cause the devices to malfunction.

This is one of the main tools for detecting osteoporosis and other bone changes, especially in the lower spine, hip, forearm and heel.
