where is yellow bone marrow located in adults
Bone marrow MRI is more sensitive and specific for assessing bone bone composition. MRI enables assessment of the average molecular composition of soft tissues, and thus provides information regarding the relative fat content of marrow. In adult humans, "yellow" fatty marrow is the dominant tissue in bones, particularly in the (peripheral) appendicular skeleton. Because fat molecules have a high T1-relaxivity, T1-weighted imaging sequences show "yellow" fatty marrow as bright (hyperintense). Furthermore, normal fatty marrow loses signal on fat-saturation sequences, in a similar pattern to subcutaneous fat.
Bilirubin Hyperbilirubinemia is a higher-than-normal level of bilirubin in the blood. For adults, this is any level above 170 μmol/l and for newborns 340 µmol/l and critical hyperbilirubinemia 425 µmol/l.
