From Lulu.com:

This is the case book for my Medical Student's Guide to the Plain Chest Film. It takes the student through a series of increasingly-difficult chest films. For each case, first use a systematic method (such as my "CLAVICLE" system) to analyze the film, make up your mind about what is wrong with the patient, then read my description. For every case I go through every step of the CLAVICLE method.
