Do the statistics reflect the no. of
incidents and what can we learn from
incidents?
Can eLearning help improve safety
practice and what else is needed?
New technologies, new concerns

2005-2009 a 180% (FDA) or 500% ↑ incident reporting – which is it?
Texas studyProjectile incidents
happen every month
Each scanner due a serious incident
every 5yrs
Dr Kanal described that the reported
FDA incidents were not ‘even the tip of
the iceberg’
Typical UK reports -incidents reported to the MHRA 2014

If we knew the number of incidents that occur would that help to prevent them from happening?

Can we learn from cylinder incidents and when will they stop?

Not stopping any time soon - *MAUDE April 2017
GE scanner
Anaesthetist brought a ferrous oxygen cylinder into the scan room while staff were preparing a patient for their scan
The cylinder hit a physician in the room, resulting in a fractured nose
What we can do is train staff in how to deal with incidents in MRI when they happen using drills and simulation but who has the time?

Burns are the most reported incident
The most reported MRI adverse
incident (England) is due to burns
70% of all injuries in MRI attributed to
burns
Radiofrequency fields used in MR create thermal heating leading to:•heat stress•induced current burns•contact burns

Capsule Endoscopy August 2017
Pill sized capsule contains a colour camera, battery, light and transmitter.
Takes 2 pictures/sec. for 8 hrs.
Near miss as referring doctor omitted to mention it and the patient forgot.
Demonstrates the need for safety education for referrers

MRI Adverse Event –6 MRI Safety Subcategories for Reporting systems
Typical examples of incidents which fit this category
Non Declared Internal Passive Metallic Implant aneurysm clip, coils, stents, filters, prosthesis
Non Declared Internal Active Metallic Implant pacemaker, cochlear implant, neurostimulator, baclofen pump, insulin pump
RF Heating or Burn Incident flesh loops, cable heating, long metal implants, retained wires, equipment related
Equipment Failure oxygen sensor, fire, flood, contrast injectors, quench
External ferromagnetic object/ Projectile oxygen cylinder, chairs, trolleys, drip stand, coin, lighter, pen, badge, pager, phone, glasses, earring
Breach of Local Rules unauthorised access/inadequate supervision of unauthorised staff, equipment wrongly labelled
Other Any MRI incident which cannot be classified above
