the brant covers (almost) all aspects of radiology. most chapters are easy to read. overall probably a little heavy for a MS3/4 unless you are REALLY interested in radiology and want to get a little head start before your residency.
problem with the brant is that you cannot just carry it around with you bc it weighs like 10 pounds. so i ended up copying the whole book chapter by chapter to be able to read at other places ...
third edition should be coming out in mid 2006
