Chapter 74 discusses anemia conditions including sickle cell disease and thalassemia. Anemia is a condition of decreased oxygen delivery to organs caused by a deficit of functional red blood cells. It is a very common clinical condition and has a wide variety of causes. Of the common causes, the hemoglobinopathies have the most characteristic imaging findings. There are common imaging findings secondary to the compensatory increase in red blood cell and precursor number. Radiographs are a standard initial imaging study. MRI is the most sensitive imaging study for the sequelae of anemia. Iron deficiency anemia is treated with iron supplementation, aplastic anemia is treated by removal of the inciting agent, and painful crises of sickle cell are treated symptomatically.
