The following question has been sent by Akhilesh Singh: CT coronary angio – what is the normal range of calcium score? Ralf Bauer,  MD, Clinic of the Goethe University, Frankfurt, Germany: Dear Mr. Singh, thank you for your question! But actually, it is not easy to answer. First, there is no real “normal” range. … Read more

To overcome the limitations of the classical volume scoring method for quantifying coronary calcifications, including accuracy, variability between examinations, and dependency on plaque density and acquisition parameters, a mesh-based volume measurement method has been developed. It was evaluated and compared with the classical volume scoring method for accuracy, i.e., the normalized … Read more

Purpose The purpose of this study was to assess the radiation dose and associated image noise of previously suggested calcium scoring protocols using dual-source CT. Methods One hundred consecutive patients underwent coronary calcium scoring using dual-source CT. Patients were randomly assigned to five different protocols: retrospective ECG-gating and tube current reduction to … Read more
