Insights

Pediatric hemoglobinopathies like sickle cell disease and beta-thalassemia present diverse imaging findings. This review details common radiographic and cross-sectional imaging features, considering hemosiderosis and chelation therapy effects.

Area of Science:

  • Medical Imaging
  • Genetics
  • Pediatrics

Background:

  • Hemoglobinopathies are genetic blood disorders with varied clinical and imaging presentations.
  • Pediatric imaging is complicated by hemosiderosis and chelation therapy side effects.
  • Technological advancements have improved the imaging of these conditions.

Purpose of the Study:

  • To review and illustrate common imaging findings in pediatric sickle cell disease and beta-thalassemia.
  • To highlight the evolution of imaging techniques for hemoglobinopathies.
  • To provide a resource for radiologists and clinicians managing these pediatric patients.

Main Methods:

  • Review of radiographic and cross-sectional imaging studies.
  • Illustration of characteristic findings in sickle cell disease and beta-thalassemia.
  • Discussion of imaging features influenced by hemosiderosis and treatment.

Main Results:

  • Detailed description of common bone, spleen, liver, and other organ abnormalities.
  • Radiographic examples of characteristic changes such as bone infarcts, dactylitis, and extramedullary hematopoiesis.
  • Cross-sectional imaging findings including iron overload and treatment-related changes.

Conclusions:

  • Sickle cell disease and beta-thalassemia exhibit distinct yet overlapping imaging patterns in children.
  • Accurate interpretation of imaging is crucial for diagnosis and management.
  • Understanding imaging evolution aids in optimizing patient care for hemoglobinopathies.

Hemoglobin01:24

Hemoglobin

Hemoglobin is a globular protein made up of four subunits. Two of these subunits are alpha chains, and the other two are beta chains. Each subunit contains a molecule of heme, which has an iron atom and can bind to oxygen. When an oxygen molecule binds to one heme group, it changes the shape of hemoglobin, making it easier for the other heme groups to bind oxygen as well.
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...

Disorders of Erythrocytes01:27

Disorders of Erythrocytes

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...

Overview of Hematopoiesis01:20

Overview of Hematopoiesis

Hematopoiesis, or blood cell production, is a vital biological process that begins early in embryonic development and continues throughout life. This process generates the various types of cells found in blood, including red blood cells, white blood cells, and platelets from hematopoietic stem cells (HSCs).
Developmental Phases of Hematopoiesis
Initially, HSCs are formed in the embryonic yolk sac, a critical site for early blood cell production. These stem cells subsequently migrate to other...

Gene Families01:57

Gene Families

Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...
