Neurological disorders encompass a broad spectrum of conditions that affect the brain, spinal cord, and peripheral nerves, leading to a wide range of symptoms and impairments. Understanding the underlying mechanisms and identifying early diagnostic markers are crucial for effective management and treatment of these disorders. In recent years, Positron Emission Tomography (PET) Scanners have emerged as powerful neuroimaging tools that provide unique insights into the functioning and pathology of the brain. PET scanners are advanced medical imaging devices that utilize positron-emitting radiotracers to visualize and measure physiological processes in the body. These scanners operate on the principle of detecting gamma rays emitted from the patient's body after the administration of a radiotracer. The radiotracer, typically a compound labeled with a positron-emitting isotope, is injected into the patient's bloodstream and accumulates in the target tissue or organ. As the radiotracer undergoes decay, it emits positrons that annihilate with electrons, resulting in the emission of gamma rays that can be detected by the Positron Emission Tomography (PET) Scanners. The collected data is then reconstructed to create three-dimensional images that represent the functional and molecular activity within the body. Neuroimaging techniques, including PET scanners, have revolutionized our understanding of the brain and its disorders. PET scans provide valuable information about brain metabolism, blood flow, oxygen utilization, and receptor binding. By visualizing these processes, PET scanners enable clinicians and researchers to gain insights into the functioning of the brain in both health and disease. In the context of neurological disorders, PET scans play a crucial role in the diagnosis, staging, and monitoring of various conditions. Positron Emission Tomography (PET) Scanners offer unique advantages in the diagnosis and staging of neurological disorders. In conditions such as Alzheimer's disease, PET scans can detect the characteristic accumulation of amyloid plaques and neurofibrillary tangles in the brain, aiding in early diagnosis and differentiating it from other forms of dementia. Similarly, PET scans can identify hypometabolism patterns in specific brain regions associated with Parkinson's disease, aiding in its diagnosis and monitoring disease progression. PET scans are also instrumental in the evaluation and staging of brain tumors, providing information about tumor metabolism, grade, and response to treatment. The Veterinary Diagnostic Imaging Market was valued at US$ 900.4 million in 2022 and is anticipated to grow at a CAGR of 7.32% from 2023 to 2030 to reach US$ 1578.6 million. Due to the rising zoonotic/chronic disease burden and increasing pet population worldwide, the Veterinary Diagnostic Imaging Market is expanding rapidly on a global scale. Additionally, it is anticipated that increased spending on animal health and rising need for veterinary diagnostics will accelerate market expansion. Positron Emission Tomography (PET) Scanners provide crucial insights into the functional aspects of the brain in neurological disorders. By measuring regional cerebral blood flow and glucose metabolism, PET scans can help identify abnormalities in brain activity. For instance, in epilepsy, PET scans can localize the epileptic focus by identifying regions of abnormal glucose metabolism. In psychiatric disorders such as schizophrenia, PET scans have been used to investigate neurotransmitter receptor function and identify abnormalities in specific brain circuits. Furthermore, PET scans can also aid in understanding the pathology of neurodegenerative disorders by mapping the distribution of abnormal protein aggregates such as tau and alpha-synuclein.
