Cross Sectional L3 Ct Image Used To Measure Subcutaneous Fat Red Download scientific diagram | cross sectional l3 ct image used to measure subcutaneous fat (red), skeletal muscle (green) and visceral fat (blue) using preoperative (a) and postchemotherapy ct (b. Computed tomography (ct) measurements of skeletal muscle cross sectional area (sma) performed at the third lumbar vertebra (l3) are prevalent in assessments of sarcopenic low muscle mass 2,3,4,5,6.
Cross Sectional L3 Ct Image Used To Measure Subcutaneous Fat Red The visceral to subcutaneous ratio of the fat area (vsr) was also calculated. two experts have more than 5 years of clinical work experience and are skilled in using image j software. one of the experts outlined skeletal muscle, psoas muscle, subcutaneous fat, and visceral fat on ct images. another expert checked the results of the contours. Ct images can be used to evaluate muscle tissue, visceral adipose tissue (vat), and subcutaneous adipose tissue (sat) compartments. manual and semiautomatic segmentation methods are still the gold standards. the segmentation of skeletal muscle tissue and vat and sat compartments is most often performed at the level of the 3rd lumbar vertebra. We used a single slice cross sectional ct image at the level of l3 for body composition analysis. subcutaneous fat water area was not associated with os when examined as a dichotomous variable. B classical cross sectional area evaluation at the l3 level showing muscle area and muscle density in hounsfield unit. c whole body ct images taken with different planes showing some examples to estimate fatty tissue (green), muscular tissue (red), and subcutaneous fat (purple). note that seeding method has been used; therefore, manual.
