An international study compared the signal intensities of hepatospecific contrast enhancement in dysplastic nodules and hepatocellular carcinomas at different stages. The contrast agent Gd-EOB-DTPA might serve as a useful marker for differentiation.
Estimated CT scanner radiation output based on scan-generated topograms is quite close to the actual dose index. Simulated protocols show that automated kilovoltage protocols (kVp) are able to decrease radiation dose even further.
Predicting radiation doses as precisely as possible helps keeping radiation dose as low as possible. A well-thought-out simulation model estimates radiation doses in the most radiosensitive patient group prior to the scan.
Swiss study results point to the important link between patient age and relative signal enhancement ratios of gadoxetic acid-enhanced liver MRI. However, uptake and depletion of the contrast agent seem not to be influenced by age.
