I’ve had two MRI scans since a motorbike accident in November. The first appointment I attended was too close to surgery on my wrist, which had been pinned and plated four weeks prior to the scan, so I had to go back two weeks later – apparently, the ‘safe’ limit is six to eight weeks. Other than this, no problems. Not sure where somafunk picked up that information, the staff who carried mine out weren’t particularly concerned. The scan itself is very noisy, and really claustrophobic. Luckily, they only usually take around 30 – 40 minutes. Good luck!
