This easy-to-understand pocket guide, in the highly-respected Clark's family of radiology texts, is an invaluable tool for students, assistant practitioners and radiographers. It provides an accessible introduction to the subject in a readble style, with plentiful diagrams and photographs to support the text.

In contemporary pedagogy, 'class' has become one nomadic sign among others: it has no referent but only contingent allusions to similarly traveling signs. This text brings back class as a materialist analysis of social inequalities originating at the point of production and reproduced in all cultural practices.

The book shows how class has not disappeared, but is known and spoken in a myriad of different ways, always working through other categorizations of nation, race, gender and sexuality.
