About this test

CT coronary angiography assesses the coronary arteries non-invasively, and is particularly good at excluding significant disease in someone with chest pain and moderate risk — a normal study makes coronary artery disease very unlikely and avoids an invasive angiogram.

What it measures

  • Coronary calcium score
  • Degree and location of any narrowing
  • Plaque characterisation

A note on results. A single test is one part of a clinical picture, not a diagnosis. Discuss your report with a qualified doctor, who will read it alongside your history and examination.
