When I was a Cardiology fellow at UMass Medical Center, there was a technician who would use a certain word to mean "a little". It sounded like /a ditzle/. I never asked her how it was spelled and later when I tried to look for the spelling in dictionaries, I never found it. The context would be something like: "Can you see any regurgitation on the screen?", "Just a "ditzle", meaning "very little". My question is: does such a word exist at all? If so, how do you spell it? Or is it some sort of slang or baby talk?
Edit (after accepting @Tim Romano's answer) - The ultrasound technician I mentioned above had worked at Radiology. I bet she incorporated the word into her vocabulary, meaning something very small.
