Question: I had a heart CT with and without contrast. A ct-angiogram, as I understand.
The radiologist report came back clean - 0 plaque score, but something different to have checked in my lung.
Out of curiosity, I looked at the images for the study and was alarmed at a large 'bright' area that appeared to be right in the Superior Vena Cava (as best I've learned from google) and into my right atrium.
The Hu scale (per the various software readers I've used) indicated hardness of anywhere from 1100 to 2200. It's alarming on the face of it. I haven't been able to get anyone to explain it to me.
i.e. Yes, it is something to look at with a second opinion or No, it's just a bulk of contrast, and its always seen and appropriately dismissed by radiologists.

p.s. I tried to upload screen shots, but missed one - the Sagittal view. I don't know how to go back to add it. The red highlights are my thresholds which are very high - up in the bone values, I believe.

Thank you so much, I very much appreciate the explanation!
