WHAT PROHANCE
IS USED FOR AND HOW IT WORKS
Prohance
®
is a substance known as a paramagnetic contrast medium. It is used
in magnetic resonance imaging (MRI) to
enhance or improve the scans or images (pictures) of certain parts of
the body (in particular, the brain, spine and
surrounding tissue), obtained by MRI alone.
ProHance
®
can also be used for whole body MRI, including the head, neck,
liver, breast, musculoskeletal system (all of
the muscles, bones, joints and related structures that are
involved in the movement of the parts and organs of the body)
and diseases of the soft tissues.
ProHance
®
is given by injection into a vein. ProHance
®
is not recommended for use in children under the age of 2 years
as
there is not enough experience with the use of ProHance
®
in this group. MRI is a relatively new medical technology which
uses magnetic fields and radio waves to produce images of parts of
the body, which a doctor can then use to make a
diagnosis. MRI examinations are carried out specialist doctors
called radiologists, using sophisticated medical
equipment. MRI does not use X-rays and therefore the minor risks
associated with X-rays are avoided.
