Yesterday, Jan. 6th, went to PAMF Mt.View Imaging Center for a coronary CT-scan which was ordered by Dr. Brandt. I took 150mg Prednisone for my allergy to the contrast material, but when I arrived, I was told they couldn't give me the scan because Dr. Brandt didn't prescribe BetaBlocker for me (first I heard of it). This wasn't first time, he failed to prescribe proper test for this scan. I had a liver panel test which was unnecessary, and should have been prescribed, instead, a basic metabolic test. I had a serious problem communicating with this doctor online; he never seemed to answer my questions adequately. I don't think he should be seeing patients.
