And I remember it being quite a daunting experience.
I was working for the then Northern Ireland First Minister David Trimble and Mo Mowlam was Northern Ireland Secretary of State. Mo was continuing her well-publicised battle against a brain tumour which ultimately and tragically cost her her life.
And when I was transported into the scanner, all I could think of was her.
Tonight I had my second CT scan at the Leed General Infirmary - my sinusitis is back - and, for the first couple of moments, it was a case of deju vu all over again.
But then, as is my wont, my mind began to wander.
The next thing I knew was being woken up by a nurse,
"Oh, sorry," I said, "how long have I been in there?"
"Four minutes," she replied.
Well, I have been very tired of late. But at least I appear to have conquered my dislike of CT scanners.
