After I had a heart attack I was told that there’s no value in doing this test at that point. A couple years later at age 40 another doctor did order it for me and my score was 0, which apparently tells me I’m not on the verge of another heart attack, so that’s nice.

the score itself isn't the only relevant thing in the report. ask to see what the radiologist actually wrote and read it yourself. ai, aided by clarifications by a cardiologist, helped me understand the details immensely
