About ten years ago, when I was cutting my eye teeth in nuclear medicine (an admission, incidentally, which stamps me as a grandfather in the field by anyone's criteria), organ scanning meant thyroid scanning and not much else. Our scanner's collimator had one narrow hole (today they make them with 4,000 holes), and the chance of "seeing" a tumor the size of a lemon in a liver was mighty small indeed. Now, with imaginative instrumentation (most of the imagination coming from university laboratories, not from industry) and short-lived radiopharmaceuticals (ditto), organ scanning has become the backbone of every nuclear medicine department.
As knowledge grows, so does the necessity of codify it, and scintillation scanning is no exception. Although there are several excellent texts on nuclear medicine available, organ scanning has reached the stage in its development when it deserves its own book; Clinical Scintillation Scanning attempts to fill this void.
