I understand regular ultrasound & doppler ultrasound & use it in my current career...my question was specifically about IVUS & I thought I had saw or read at some point that there was radiation used in conjunction with IVUS
IVUS is used during the procedure, so there is the radiation of the procedure (for the xrays) being used through the procedure. Since IVUS prolongs the procedure a bit, both for the time it takes to get the ivus in place and to take and interpret the images and, since ivus makes it more likely to find something, to then treat what is found, the use of IVUS will result in a potentially longer procedure with more radiation too. That said, my own procedure used IVUS and was an hour-and-fifteen-minute miracle, so it is possible to still have a shorter procedure with the use of IVUS.
It is the choice of the doctor, Dr. Makris in this instance, to use or not use IVUS; cost is a factor but so is if he has the expertise to understand its images and make use of it and also if he considers it something that will add value to his diagnostics during the procedure or not. I expect Dr. Sclafani to continue presenting his findings on the use of IVUS - he has a presentation on this at ISNVD next month - and that he'll win other doctors over to its use, because it is an amazing tool.
As patients, choosing a doctor is a big choice and the use of IVUS is only one factor, although an important one to me.
