结局指标
主要结局
stable Image Quality in reduced dose scans
时间窗: through study completion, an average of 1 year
Recorded values compared in 2 populations-different contrast agents by using qualitative\&quantitative methods Qualitative:diagnostic certainty, assessability of lung structure/lesions,diagnostic reliability, Quantitative:Assessment of tissue composition,diagnostic performance measurements Attenuation/sealing measurement (HU), signal-to-noise ratio (SNR), contrast-to-noise ratio ,size dimensions of lung structure/lesion in three dimensions in millimeters Tissue composition assessment diagnostic performance measurements (sensitivity, specificity, accuracy) diagnostic confidence: 1-4 Theses measurements will be put in correlation to the scan dose (mSv) per patient, forming two groups with matched BMI (kg/m\^2)
Dose Reduction by new scanner
时间窗: through study completion, an average of 1 year
mSv per exam will be recorded. This value will be put in correlation to weight (Kg), height (cm) and BMI.
