123I-IBZM

[^123I]IBZM (Iodine-123 Iodobenzazepine) is a specialized radioactive tracer used in brain imaging to study dopamine receptors, particularly D2 receptors. When injected into the body, it binds selectively to these receptors in the brain regions involved in movement and reward. Using a type of camera called a SPECT scanner, doctors can visualize and measure the distribution of the tracer, helping diagnose conditions like Parkinson's disease or schizophrenia. This technique provides valuable insights into the functioning of dopamine systems, aiding in disease assessment and treatment planning.
