The CT signs of hypovolemia should not be discarded so abruptly. Just like 
any other sign, clinical or otherwise, there is value in the observation. 
When the aorta and vena caval diameters are shrunken to less than a 
centimeter, woe to those who would dismiss this. they will regret it like 
dismissing other signs of hypovolemia. Because they are virtual signs does 
not mean that they are not valid. Auscultation, just like CT,  is merely a 
representation, a reflection of reality, not reality itself dependent upon 
hearing, vibrations and ambient noise.  The bias against radiological signs 
reflects a view from the past when xrays were merely shadows. CT is a pretty 
sophisticated tool and while it may be misinterpreted like, as rick says, 
other signs, it is far more accurate than many other findings that we rely 
upon.
