[18F] - FD17 PET Imaging of α-synuclein: A Clinical Study in α-synucleinopathy Patients

The main objective of this study is to establish a standardized method for [18F] - FD17 PET imaging in α-synucleinopathy patients, and to analyze its physiological distribution in healthy individuals as well as its pathological distribution in α-synucleinopathy patients, including Parkinson's disease (PD), multiple system atrophy (MSA), and idiopathic rapid-eye-movement sleep behavior disorder (iRBD). Specifically, [18F] - FD17 PET imaging focuses on evaluating the deposition of α-synuclein and exploring the diagnostic value of [18F] - FD17 PET in PD, MSA, and iRBD patients. In addition, for PD, MSA and RBD patients, dopamine transporter(DAT)-PET imaging was performed to evaluate the distribution and density of DAT in brain. The study aims not only to clarify the specific binding mode of the imaging agent in different α-synucleinopathies, but also to evaluate its efficacy and potential application prospects in early diagnosis , providing new methods for the diagnosis and treatment of neurodegenerative diseases. This study is expected to contribute to early pathological detection and accurate diagnosis in clinical practice.

[18F] - FD17 PET imaging

Primary outcomes

  1. electrocardiogram

    Time frame: 2 weeks ahead of and after [18F] - FD17 PET/MRI

    Heart rate, atrial rate, ventricular rate, P-R interval, QRS axis, QRS duration, QRS potential, and all other electrocardiographic indicators will be collected by 12-lead electrocardiogram. These outcomes will be used to figure out whether the subjects have a potential heart disease and whether [18F] - FD17 PET/MRI will do harm to subjects.

  2. routine blood test

    Time frame: 2 weeks ahead of and after [18F] - FD17 PET/MRI

    10ml peripheral venous blood will be collected and to measure red blood cell cell count and percentage, hemoglobin content, white blood cell count and percentage, platelet count, and all other indicators in routine blood test. These outcomes will be used to figure out whether the subjects have a potential disease and whether [18F] - FD17 PET/MRI will do harm to subjects.

  3. routine urine test

    Time frame: 2 weeks ahead of and after [18F] - FD17 PET/MRI

    20ml urine will be collected for routine urine test. Indicators including red blood cell and white blood cell count under a microscope, urine specific gravity, urine PH, urinary protein, glucose in urine and all others will be measured. These outcomes will be used to figure out whether the subjects have a potential disease and whether [18F] - FD17 PET/MRI will do harm to subjects.

  4. liver renal function test

    Time frame: 2 weeks ahead of and after [18F] - FD17 PET/MRI

    10ml peripheral venous blood will be collected and to measure alanine aminotransferase(ALT), aspartate aminotransferase(AST), alkaline phosphatase(ALP), Gamma-glutamyltransferase(GGT), creatinine, urea nitrogen, uric acid and all other liver renal function test indicators in serum. These outcomes will be used to figure out whether the subjects have potential hepatorenal dysfunction and whether [18F] - FD17 PET/MRI will do harm to subjects.

Secondary outcomes
