I hate to break it to you guys but the definitive source for CT readings is the radiologist - not the refering physician. In fact, refering physicians rarely even get the full resolution scans. You can have your oral surgeon look at scans but that's why they pay reading radiologists the big bucks. It is a specialty after all. Typically it's the MO who will order them and give you a summary of the reading. You may be refered to an ENT or head & neck surgeon for "direct visualization" if they don't like what they see or have "regions of interest". Most of us have had false positives in early post Tx scans so don't let that get to you.

Also bear in mind that any scan is only a small component of the total diagnostic package and in themselves are typically not definitive.
