The partition coefficients of 133Xe between human blood and bone.
The partition coefficients of 133Xe between blood and haematopoietic bone marrow and homogenised bone have been determined in vitro. The partition coefficient lambda 1 corresponding to haematopoietic marrow was 0.95 ml g-1 while that corresponding to homogenised bone was a function of age, lambda 2 = 3.11 + 0.049(age)(ml g-1). These data can be used for calculating regional blood flow in healthy human femur by means of a simple 133Xe radionuclide method.
