What is the correlation between use of Gd and NSF? ......
ANSWER ....... Studies have indicated a correlation
between the use of Gadolinium based contrast agents and
NSF. There have been no reports in patients with normal
renal function. Virtually all cases have occurred in dialysis
dependant patients. Most cases have occurred at higher
doses such as those used for MRA examinations.
Cumulative doses also need consideration. All reported
cases have occurred with an associated pro-inflammatory
event-surgery, systemic infection, thromboembolic event
(eg limb ischaemia). Liver transplant patients are also at
risk. Due to this recent complication prudent use of
contrast in MRI is needed. It is particularly important to

What EGFR is considered severe renal failure and how
should GBCA administration proceed? ...... ANSWER
....... Severe renal failure -GFR <30ml/min/1.73 m •
Absolute contra-indication unless contrast administration
is essential and the benefits out way the risks
What EGFR is considered moderate renal failure and how
should GBCA administration proceed? ...... ANSWER
....... Moderate renal failure - GFR = 30-60
ml/min/1.73m • gadolinium given with caution if
inpatient and pro-inflammatory event
What EGFR is considered normal renal failure and how
should GBCA administration proceed? ...... ANSWER
....... Gadolinium administration can occur In at risk
patients doses should not be repeated within the same 7
day period. In at risk patients the FDA recommends
dialysis despite the fact that current studies are yet to prove
it to be of benefit. Dialysis in at risk patients should be
performed within two hours.

What is magnetism? ...... ANSWER ....... Magnetic
susceptibility is a measure of the extent to which a
substance becomes magnetised when placed in a magnetic
field. These interactions will concentrate or disperse the
lines of the magnetic field and either increase or decrease
the local field strength
What are paramagnetic substances? ...... ANSWER .......
• magnetise in the direction of the applied field ie. have a
positive susceptibility (+10)
• increase the local field strength
• include chelates of metals such as iron, copper and
gadolinium
What are diamagnetic substances? ...... ANSWER ....... •
magnetise in the opposite direction to the applied field ie. a
negative susceptibility (-1)
• reduce the local field strength
• include water and most organic molecule
What are ferromagnetic substances? ...... ANSWER .......
• have an extremely large positive susceptibility (+25,000) •
can substantially increase the induced field and so are used
in electromagnets • have a magnet 'memory' ie. will retain
, 4|Page
magnetisation after the applied field is removed • include
iron, nickel and cobalt alloy
What are superparamagnetic substances? ...... ANSWER
....... • have a large positive susceptibility (+5000) • have
no magnetic 'memory' • small Fe3SO4
What are permanent magnets? ...... ANSWER .......
Permanent Magnets • vertically orientated field requiring
solenoidal RF coils • low field strength - up to around 0.3
Tesla • very low fringe fields since the magnet frame
provides a return path for the magnetic flux • very heavy
What are air core resistive magnets? ...... ANSWER .......
• horizontally oriented field produced by current flowing in
a resistive coil of wire • require a continual supply of
electrical power • low field strength - up to around 0.3
Tesla • can be turned off at the end of each day
What are iron core resistive magnets? ...... ANSWER
....... • hybrid of permanent and resistive designs •
vertically oriented field requiring solenoidal RF coils • low
field - up to around 0.6 Tesla • low fringe fields
