A few weeks ago I posted my layperson’s summary of why there’s even an issue with metal and MRI (click here to read that post on MRI and Metal). In this posting, I hope to explain why it’s so critical to find metals, particularly ferromagnetic metals, being carried by people or inside objects.

Of Nails, Noses, MRIs And Ferromagnetic Detection
Friday, April 3rd, 2009A very common question asked about ferromagnetic detection systems is, “will it find __________ [insert the object of your choice: pacemaker, cell phone, pocket knife, intra-orbital fragments...]?” Funny, but in the hundreds, if not thousands, of times that question has been posed to me, never once has it been, “will it find a nail I stuck in my nose 30 years ago?”

One of most frequent is, “why do I have to remove all metal before an MRI,” or it’s corollary, “can I get an MRI with some metal on (or in) me?” To answer these questions, let’s start at the very beginning…
