I know I have submitted this post before in the past but I wish people would do more studies on the accuracy of the 'muga scan'. I think it has a very large margin of error in any given reading. I really would hate to see someone prevented from getting the life saving drug herceptin because of a 'faulty' inaccurate reading from a muga scan. I will keep resubmitting this post everytime someone gets a low reading.

Hi,
I justed wanted to share my experience with muga scans. I had my first muga scan at diagnosis and it came out to be 49. They weren't sure if they would give me herceptin. I did 4 rounds of A/C and then had another muga. It then read a 58. So according to these readings, the 3 months of harsh A/C actually improved my heart significantly. My oncologist laughed at the results. Obviously there is a large margin of error in these muga scans. I would hope that no one is ever prevented from getting herceptin just because of one low muga scan reading. I for one do not put any credit in one low muga scan reading. I had a very healthy heart the whole time and had no trouble with the herceptin. Thank god, my oncologist didn't just react to the first low reading.
