How Analyze was Used
“Manual TLV measurements were performed by trained observers using Pinnacle 3 (Philips Radiation Oncology Systems) and Analyze version 9.0 (Analyze Direct, Inc.). Liver boundaries were contoured on each axial slice and TLV was subsequently calculated by multiplying the contoured area by the spacing between slices. Extrahepatic structures (e.g., gallbladder, portal vein, and caval vein) were excluded from the liver boundaries if visible. Before inclusion in the database, all liver segmentations were checked for completeness and all reported volumes were recalculated by another independent observer. All observers were blinded for time point, patient ID, and previous measured volumes for all measurements.”
