questions about the different CT scan interpretations

Several people have asked why the Cedar Sinai doc said the CT scan was
clear and the Hoag doc said that there was something on the lower left
lung...

Yep, they both saw the same scan. We feel that the Hoag doctor took
more time to actually look at it though.
The Cedar Sinai doctor just had the disk with the images on it and
didn't say anything about any of the findings.
The Hoag doctor looked at the same disk and reported the concern about
the thing found in the lung.
We also had the radiologist fax us his initial written report which also
indicated something in the lung which coincided with the Hoag doctor's
findings.
