        "...... many centers allow patients to listen to music during the
        scan ...... All magnetic objects such as keys must be removed."
        How do they manage to play music while speakers and headphones contain
        magnets?
        \_ Here's an obvious guess.  You know the tube-based earphone they use
           on airplanes?  They're made of nothing but plastic tubes and plugs.
           \_ So maybe the clinics use very long tube-based earphones connected
              to magnetic speakers far away.
              \_ i've noticed that recently, the "wire" that cops have going
                 to their ear to listen to their radio with is also a tube.
                 cool.
