Central neurotransmitter and receptor imaging

Central neurotransmitter and receptor imaging is a specific ligand labeled with a radionuclide, and in view of receptor-ligand-specific binding properties, precise localization of specific receptor binding sites at the human brain level and acquisition of receptors Distribution, density, and affinity images; the use of radiolabeled synthetic neurotransmitter precursors to observe specific central neurotransmitter synthesis, release, binding to postsynaptic receptors, and reuptake, called neurotransmission Quality imaging. Basic Information Specialist Category: Neurological Classification: CT Applicable gender: whether men and women apply fasting: not fasting Tips: Remove metal objects from your body before imaging to prevent artifacts. Normal value The quantitative or semi-quantitative parameters of the obtained central neurotransmitters or receptors are consistent with the metrics. Clinical significance Abnormal results Quantitative or semi-quantitative parameters of central neurotransmitters or receptors can be obtained by means of physiological mathematical models to make diagnosis, treatment decisions, efficacy evaluation and prognosis for certain neurotransmitter or receptor-related diseases. People in need of examination have patients with certain neurotransmitter or receptor-related diseases. Precautions Taboo before inspection: 1. For radionuclide cerebrovascular imaging examination, radionuclide-labeled drugs must be injected. Before the patient is examined, the first-time physician should be consulted in detail and signed to confirm the radionuclide cerebrovascular imaging examination. 2. Remove metal objects from the body before imaging to prevent artifacts. 3, the recent use of tincture, patients must discharge the tincture and then make an appointment to check. Requirements for inspection: 1. Let the body relax and lie flat during the development process, and do not move the body. 2. Lumbar puncture and cerebellar medullary puncture should be performed by a neurologist. Inspection process Using specific ligands labeled with radionuclides, in view of receptor-ligand-specific binding properties, precise localization of specific receptor binding sites at the level of living human brain and acquisition of receptor distribution, density and affinity images; The precursors of the labeled synthetic neurotransmitters can also observe the synthesis, release, binding to postsynaptic membrane receptors, and reuptake of specific central neurotransmitters. Not suitable for the crowd Inappropriate crowd: 1. Those with a history of severe allergies. 2. For patients suspected of severe pulmonary vascular bed damage and severe pulmonary hypertension. 3, severely impaired kidney function, severe edema.
