Automatic combined whole-body muscle and fat volume quantification using water-fat separated MRI in postmenopausal women
2015 (English)In: International Society for Magnetic Resonance in Medicine Annual Meeting: Proceedings, 2015Conference paper, Poster (Other academic)
Quantitative and exact measurements of fat and muscle in the body are important when addressing some of the greatest health-challenges today. In this study whole-body combined regional muscle and fat volume quantification was validated in a group of postmenopausal women, where the body composition is changing. Twelve subjects were scanned with a 4-echo 3D gradient-echo sequence. Water and fat image volumes were calculated using IDEAL, and image intensity correction was performed. Subsequently, automatic tissue segmentation was established using non-rigid morphon based registration. Whole-body regional fat and muscle segmentation could be performed with excellent test-retest reliability, in a single 7-minutes MR-scan.
