Brief Summary:
This study is a diagnostic study. Patients and healthy volunteers were recruited from clinically suspected or confirmed melanoma patients to undergo 18F-PEG3-FPN PET/MR or PET/CT imaging to observe the response of the subjects after drug injection, and evaluate the efficacy of 18F-PEG3-FPN PET imaging in the diagnosis and staging of melanoma compared with 18F-FDG PET imaging. PET/CT imaging was performed in patients with contraindications to MR. The subjects underwent 18F-PEG3-FPN and 18F-FDG PET/MR or PET/CT imaging at an interval of two days, respectively. The general information, clinical data, blood routine, liver and kidney function indexes, 18F-PEG3-FPN and 18F-FDG PET/MR or PET/CT imaging results and other imaging data of the patients and volunteers were collected, and the histopathology of biopsy or surgical specimen was taken as the final diagnostic criteria. This study plans to set the sample size as 50 cases.

Detailed Description:

This team always picolinamide structure based, successfully synthesized a positron nuclide targeting melanin probe - 18-5 - f FPN [18 f - 5 - fluoro - N - (2 - (diethyl amino) ethyl) pyridine formamide] for PET imaging, we found that combining FPN and melanin with high specificity and favorable pharmacokinetic characteristics, can be sensitive to detect the tiny metastases (lung, lymph node metastasis), which shows good potential of PET imaging for melanoma.The preparation method of 18F-5-FPN is simple and can be directly synthesized and purified by GE's synthesis module automatically.Then, we optimized the probe with triethylene glycol (PEG3), 18F-PEG3-FPN, to improve the labeling rate of the probe (44.68% >;6.98%, 18F-5-FPN), reduced its uptake in the liver, improved its drug distribution in vivo, and was successfully applied in the detection of liver metastasis.The integrated TOF PET/MR imaging equipment is the most advanced imaging equipment at present, which combines the advantages of PET and MR. With the high sensitivity of PET and the high soft tissue contrast of MR, it has obvious advantages over PET/CT in head, neck, abdomen and pelvic lesions.

At the same time, MR has no additional radiation and is more biosafety. With 18 f - PEG3 - FPN in clinical potential of melanoma imaging, 18 f - this project intends to apply PEG3 - FPN integrated PET/MR imaging diagnosis and staging of malignant melanoma tumors and clinical use of 18 f - FDG PET/CT imaging contrast, design of a prospective study, explore 18 f - PEG3 - FPN detection performance of melanoma, to make up for 18 f - FDG PET imaging diagnosis and staging of melanoma value.

Arm Intervention/treatment
Experimental: 18F-PEG3-FPN PET
A positron probe for the targeted melanin
Drug: 18F-PEG3-FPN
For clinically suspected or confirmed melanoma patients and healthy volunteers, integrated PET/MR imaging was performed using targeted melanin-specific imaging agent 18F-PEG3-FPN. Meanwhile, the general imaging agent 18F-FDG was compared with MR multi-sequence and multi-parameters
Other Name: 18F-FDG

Primary Outcome Measures :
  1. Sensitivity and specificity of 18F-PEG3-FPN PET/MR for diagnosis and staging in melanoma. [ Time Frame: up to 2 years ]
    For subjects with suspected or diagnosed or treated melanoma who have completed 18F-FDG PET/CT imaging, diagnosis and staging results of 18F-PEG3-FPN PET/MR, PET/CT will be compared to 18F-FDG PET/CT imaging, pathology, clinical and follow-up result.
