    Chemical reactive. The light sensitive compound is the ferric oxalate.The contrast agent just consumes (oxidizes) more of it during the image formation process.

    You can imagine my embarrassment when after ten years of marriage I realized my wife was not saying " Talk nerdy to me".

    Let me go on the record as saying that I have never seen Clay wearing a pocket protector of any kind, let alone a pair of them. There was no implication that Clay is nerdy in my funny, but true, OT contribution to this thread.

    I do think he may have geeked out on us a little with that description, however.

    I hate to show my ignorance, but what is a pocket protector?

    Thank you Scootermm for that bit of nerd history. I remember going to school with my pocket protector filled with multi-color pens, pencils and a 6 inch plastic ruler. My trusty Pickett Slide Rule hung from my belt in its sturdy leather holster.

    Those were the days... Slide rules - Analog calculators.....

    I would quickly point out that I have never had to replace the batteries in my slide rule.

    Thanks for the graphic. I have not seen one of these in years. Not a bad idea, though. I have ruined lots of nice shirts from ink stains.
