French CAC-HIV Cohort Study

Agatston method quantified coronary calcification. A prospectively ECG-triggered, non-contrasted CAC score used a non-enhanced low radiation cardiac CT scan provided onsite at both centers. Quantification of CAC was performed using a SOMATOM Definition Edge or SOMATOM Force (Siemens Medical Solutions) with standard mediastinal parameters (width, 350 Hounsfield units; level, 50 Hounsfield units), and according to the current guidelines for CAC scoring of non-contrast non-cardiac chest CT scans.
