Bill Posted March 29, 2005 Share Posted March 29, 2005 Thanks to Fay A. for remembering my wife's PET scan and thanks to ALL for the kind words of support. My wife has finally reached her endpoint with tests and these PET scan results ( along with the Tarceva ) MUST offer some encouragement or she plans to stop tx. The PET scan went off w/o a hitch. I have a copy of the films. Now the hard part. Waiting another couple of days for the radiology report. I wanted to make a couple of comments and inquiries about the PET scan films and would like some opinions from those of you that have had a PET scan, have seen your films and the rad report. Just to look at the films I'm not very impressed. Four sheets of snapshots. Two sheets devoted to the torso. Two sheets to the head ( ~ eye level to ~ clavicle ). Not sure why so much film was used for these head shots. Nothing really to see and the brain portion is just blackened in. Is this pretty standard image selection for a PET ? OVERALL the PET scan films are grainy with very little crisp detail ( unlike an MRI ). I assume that the radiologist uses a viewing machine that allows for lighting adjustments, focus, zooming, etc ? The sequence of photos on each sheet fade in and then gradually fade out. Also, if you look at the snapshots there are obvious blackened areas. Some more solid black than others and some of these areas appear to correspond with anatomy that is suppose to be sensitive to uptake in a normal PET scan. I see solid black areas that corresponds with the pericardium and urinary bladder. I see partially blackened spotty areas that would correspond with the kidneys. It gets real tricky when you see a black streak or spot on an organ like the liver that's supposedly sensitive to uptake in a normal PET scan but can also contain cancer. This is my wife's situation. BTW, somebody mentioned that PET scans can't pick up small tumors / nodules. Sounds like the same limitation as with CT scans ? Is this true ? The one landmark that I can easily spot ( unfortunately ) is my wife's primary tumor in her upper left lung. No way to measure it's ~ size since these are wallet size snapshots but to look at it relative to the left lung and other structures I'd say that it's ~ the same size as the previously reported ~ 2.4 ~ 2.6 cm. I see some other small spots and marks within her torso. Various shades of darkness / grey. I suppose that this is where the radiologist's expertise really comes into play. BTW, there is a triangular shaped gray image midpoint on the inner edge of my wife's right lung. Sound familiar ? I'm guessing that this is her port-a-cath. I see a couple of black dots in her pelvic area and part of a couple of her vertebrate appear darker than others. Thanks again for the words of support and TIA for any PET scan opinions that you care to offer. Good , bad or indifferent I will post the PET scan results when they are released.
