The ultrasonographic images of OP could be classified to 3 types: 6 cases of interior ovary, 6 cases of exterior ovary and 9 cases of mix echo of the ovary appendage. The diagnostic incidences were 28.6%, 28.6% and 42.8%, respectively. There were 2 types of diagnostic results of 13 OP cases using TVCDUS before operation, including 9 cases of dot flow signal, 4 cases of half ring signal.

Drawing more heavily here than elsewhere on the work of other scholars, Lamont offers potted histories of the various disciplines, and so we hear echoes of the old jeremiads against postmodernism and "French theory," and we hear once more about the canon wars in English, the reflexive turn in anthropology, and, in political science, the rise of rational choice. We hear the old misleading statistics as well.
