		Red to yellow marrow conversion may be diffuse or may occur in the form of isolated or confluent islands of fatty marrow (Fig 2).
		In patients with polycythemia vera, the bone marrow of the axial skeleton is diffusely and homogeneously hypointense on T1-weighted MR images and it is indistinguishable from the diffuse marrow abnormality observed in patients with leukemia or myeloma.
		MR imaging of the marrow is a useful adjunct to bone marrow biopsy for patients who are candidates for bone marrow transplantation and, in particular, for patients with lymphoma, a disease with a well-known patchy mode of infiltration of the bone marrow.

		Blood cells are produced in the bone marrow, a jellylike substance inside the bones that is composed of, among other things, fat, blood, and special cells that turn into the various kinds of blood cells.
		Bone marrow that actively produces blood cells is called red marrow, and bone marrow that no longer produces blood cells is called yellow marrow.
		If bodily oxygen levels are low (as they would be if there are too few red blood cells circulating), the kidneys produce a hormone called erythropoietin, which stimulates the stem cells in the marrow to produce more red blood cells.

	Bone marrow
		It is made up of red marrow, which produces red and white blood cells and platelets, and yellow marrow, which contains fat and connective tissue and produces some white blood cells.
		As a person matures, the red marrow in many of the bones is replaced by yellow marrow.
		Red bone marrow is found mostly in the ribs, breastbone, shoulder blades, collarbones, hip bones, skull, and spine.

		The MR appearances of marrow in any particular bone reflects a combined effect of the relative fractions of red marrow, yellow marrow and trabecular bone.
		As conversion of red to yellow marrow occurs in the spine, yellow marrow may replace red marrow in a more focal (rather than diffuse) pattern, resulting in a spotty appearance (bright spots in T2 images) of the bone marrow.
		Bone marrow infiltration precedes osseous destruction and hence MRI is highly sensitive in detecting early marrow infiltration.

	Re: How does bone marrow produce red blood cells?
		In the bone marrow is a special type of cell called a stem cell.
		The body is constantly producing new red blood cells (and white ones as well) because red blood cells only live so long and are constantly dying.
		Bone marrow stem cells can sense this protein, and when they do, they decide more often than usual to become a red blood cell rather than a white blood cell.
