[Evaluation of Fat Quantification in the Liver Using Dual Energy CT].
Nihon Hoshasen Gijutsu Gakkai Zasshi
April 2017
Article Synopsis
- The study focuses on the increasing prevalence of nonalcoholic fatty liver disease (NAFLD) and the potential progression to more serious liver conditions like cirrhosis and cancer.
- It evaluates the effectiveness of using dual energy CT with monochromatic imaging to quantify liver fat compared to traditional imaging methods and liver biopsies conducted on 54 patients.
- Results depicted a negative correlation between CT values at 40 keV and both the steatosis area and NAFLD activity score, indicating that dual energy CT may provide better fat quantification for assessing liver health than conventional imaging.
[Usefulness of the Training of Trigger Point in Coronary CT Using Test Bolus Tracking Method].
Nihon Hoshasen Gijutsu Gakkai Zasshi
October 2015
Article Synopsis
- - The study addresses the issue of variability in contrast effects during coronary CT examinations due to reliance on operators' recognition of test bolus peak timing.
- - A training program was implemented for operators to improve their abilities in identifying optimal trigger points for better contrast use.
- - Results showed that post-training, the mean CT value of the ascending aorta increased and variability among operators decreased, leading to more consistent examination outcomes.
