Diagnostic Radiology
RAPHEX practice examinations have been helping residents
study for their board exams for over 15 years. In 1994
we compiled 9 years of exams, from 1984 through 1992.
All questions from these years were reviewed, checked
for accuracy, and questions and answers were updated to
be accurate as of May 1994. Questions were then
organized according to topic, so that residents can
concentrate on areas they need the most help in.
This book is designed to be: Well-organized for teaching or self-study
,Organized by specific subject areas ,Answers to questions include methods and rationale
This book also includes the general physics sections of
the Raphex exams.
