From the Author
Cadillac Eldorado 1957 m odel .
Andrey Yudin was born in 1957.
Much in common: the same age, the exclusive models, all options, in good working condi-
tions, with no rot and rust, sit down and drive, some problems on the body, etc.
… Long ago in some of the radiology papers, I found a discussion concerning the peculiari-
ties of the names of symptoms: if they are given the names of the authors, then we do not
understand their meaning (after all, our specialty is largely metaphorical), and if we have a
picturesque description of the image, then it is sometimes excessively emotional. As an
v
vi From the Author
e xample of a failed metaphorical formation, they cited the “1957 Cadillac Lights” sign. Not
everyone in the world does know about this car; who knows?
However, the well-known saying insists: “If you did one million bucks – buy the pink
Cadillac to success unless that luck turns away!”
I hope this publication will help you get lucky in our profession. Enjoy imaginative percep-
tion of radiology!
I want to tell the truth which I do not know, but I’m looking for it.
Professor A. Yudin
