Abstract |
|
|
| Brain neuron receptor imaging plays an essential role in understanding the mechanisms of neurotransmission and diagnosing various neurological and psychiatric disorders. Single-Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) are two widely used imaging techniques that allow for the visualization and quantification of brain receptor activity. This review compares SPECT and PET in terms of their imaging capabilities, clinical applications, and challenges. SPECT is a cost-effective tool with longer-lasting radiotracers, commonly used in clinical diagnostics. PET, however, offers superior spatial resolution and sensitivity, making it more suited for detailed receptor studies in research settings. Advances in hybrid PET/MRI systems have further enhanced the precision of PET imaging, allowing for simultaneous acquisition of functional and structural brain data. Despite these advancements, challenges remain, including the need for more specific radiotracers and reducing radiation exposure. The future of brain receptor imaging holds great potential, with advancements in artificial intelligence, personalized medicine, and the development of novel tracers. These innovations will continue to expand our understanding of brain function and improve the diagnosis and treatment of neurological diseases.
