Does scatter correction of cardiac SPECT improve image quality in the presence of high extracardiac activity?
Image quality improved significantly when SC was applied, especially when combined with maximum likelihood reconstruction with AC. This improvement was present despite increased extracardiac activity in close proximity to the heart.
This tool for statistical analysis of signals from ultrasonography using the FD-ratio can be used to accurately quantify fat in vivo in an animal model of hepatic steatosis, and may serve as a quantitative biomarker of hepatic steatosis.
