assessment of ct datasets
 
 

We have expert readers able to perform complex analyses on your cardiac CT datasets using workstations and software from all major vendors.

  • Five to ten certified readers
  • State-of-the-art software, with all major vendors present
Specific Assessment Techniques:

1. Non-Contrast Cardiac CT

  • Quantification of Coronary Artery Calcification per plaque and per patient
    • Agatston Score
    • Area and Volume
    • Mean Calcium Concentration and Mineral Mass
  • Quantification of Aortic and Mitral Valve Calcification
  • Quantification of Aortic Calcification (thoracic and abdominal aorta)

2. Contrast Enhanced Cardiac CT – Stenosis and Plaque

  • Qualitative Assessment of the presence of significant coronary artery stenosis (all segments)
  • Quantitative Assessment of the degree of stenosis (in %, in segments >2mm)
  • Qualitative Assessment of the presence and morphology of coronary atherosclerotic plaque (per segment, calcified vs. non-calcified plaque, all segments)
  • Quantitative Assessment of area and volume of coronary atherosclerotic plaque (coronary artery > 3mm)
  • Quantitative Assessment of CT attenuation of non-calcified coronary atherosclerotic plaque (coronary artery > 3mm)
  • Quantitative Assessment of coronary plaque remodeling (Remodeling index, coronary artery > 3mm)

3. Contrast Enhanced Cardiac CT –
Left Ventricular (LV) Function and Perfusion

  • Qualitative Assessment of global and regional (17 segments) LV rest function
  • Quantitative Assessment of global LV function (ejection fraction in %, end-diastolic and end-systolic volumes in ml) and LV myocardial mass (in g)
  • Qualitative and quantitative assessment of perfusion defects
  • Qualitative and quantitative assessment of infarct size (in % of total LV myocardium and cm3)  

4. Incidental Findings

  • Identification and reporting of Incidental Findings (full field of view – thorax)
