Why are MRI's so noisy?
Many MRI machines are noisy, but the
multipositional scanner at the East Bay Upright MRI Center contains
special features that greatly reduce the noise level.
Not all MRIs are noisy but those that
are noisy are noisy because of vibrating gradients, the adjunctive,
non-uniform magnetic fields that enable the scanner to collect
data from a particular cross-sectional plane. These gradient
vibrations have been reduced to a minimum in the East Bay Upright MRI
Center scanner. For many patients, these "whisper quiet"
gradients are a welcome change from the noise and stress associated
with competitive machines.
Furthermore, because the main magnetic
field in our multipositional scanner is vertical, enabling
an open patient environment, what little noise is present
is dissipated rather than concentrated. In fact, our machine
is so quiet that patients often fall asleep.
It stands to reason, of course, that
an open patient environment contributes to a relaxed patient
and thus improved image quality. Optimum image quality, of
course, translates into images that provide optimum diagnostic
information to the radiologist.
