PeterW,
What is it that I want to know that the cardiologist didn't already bore me with? Well everything. LOL!!
I am a naturally curious person. It is not every day that I get to see inside my body. So, seeing arteries and valves and how they open and close and know that it is my heart is neat to me.
Obviously nothing was too bad about either test since they have let me go home and to work without any restrictions. No one has said I need to be admitted to a hospital and to be prepped for immediate surgery.

Yet, I now have discs that have data on them that I could not easily see/read.
With a little Googling, watching YouTube videos and reading a few articles, I now understand more (better even then with my doctor) about what the DICOM imagery of my recent nuclear stress test means. I now get the meaning of the areas in yellow and purple, red or green. What the darker vs. lighter parts mean and can look at them in the privacy of my home, on my computer, without knowing another patient is out in the waiting room ready to come in next and so, my time is limited with the cardiologist. I now get the whole Perfusion, VLA, HSA, SA, resting image and stress image, short axis and vertical long rest, etc. 2D and 3D images. I can playback the video and animated gifs and see my heart and lungs and stomach in ways I have never seen before.
Bottom line is that the tests were normal. Well, at least the nuclear stress test was. Did not get that answer yet for yesterday's echo test. I just didn't like getting a disc that was made with the assumption I had a Windows computer and so, information on/about my body was inaccessible to me. I wouldn't want to pull up to a gas station needing regular unleaded gas and be given diesel instead. I went to the cardiologist and got a Windows CD when I am an Apple Macintosh guy.
I have the older Mac Mini up and running with Bootcamp and Windows 7 now. It has been a few years since it was used. So, it is in the process of doing about 50K updates and it is reminding me why I hate Windows. Apple updates, Bootcamp updates, Windows updates and service packs, anti-virus definition updates, etc. Sheesh! I hope it will all be finished by late this evening and I can look at the echo data on that CD.
