Filter by:The goal of this observational study is to evaluate the diagnostic efficacy and the safety of the combined approach with β-probe and 68Ga-PSMA-11 PET/CT in the correct identification of lymph node metastases, in high-risk prostate cancer patients undergoing radical prostatectomy and pelvic lymph node dissection.
As a new dual receptor (integrin αvβ3 and FAP) targeting PET radiotracer, 68Ga-FAPI-RGD is promising as an excellent imaging agent applicable to various cancers. In this research, we investigate the safety, biodistribution and radiation dosimetry of 68Ga-FAPI-RGD in healthy volunteers. Moreover, we evaluate the potential usefulness of 68Ga-FAPI-RGD positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various types of cancer, and compared with 18F-FDG PET/CT.
In this study, the investigators aim to provide a deeper understanding of Parkinson's disease and find a biomarker of Parkinson's disease. This is done using imaging scans called Positron Emission tomography (PET), Single Photon Emission Computed Tomography (SPECT), and Magnetic Resonance Imaging (MRI). The findings will provide a deeper understanding of the brain changes in Parkinson's disease. More importantly, this study will help with the discovery and development of new medications aiming to delay progression of Parkinson's disease symptoms
In this study, the researchers aim to find a biomarker of PD. Using imaging scans called Positron Emission tomography (PET), Single Photon Emission Computed Tomography (SPECT), and Magnetic Resonance Imaging (MRI). The PET and SPECT scans use small amounts of radiation and specific compounds called tracers, to study chemical changes in the brain in a way not possible with any other procedure. The MRI uses magnetic fields to generate images of brain structure and function
As an emerging molecule targeting FAP, 68Ga-FAP-CHX is promising as an excellent imaging agent applicable to various cancers. In this study, we observed the safety, biodistribution and radiation dosimetry of 68Ga-FAP-CHX in patients with various types of cancer and compared them with the results of 68Ga-FAPI-04 or 18F-FDG imaging to evaluate the dosimetric characteristics and diagnostic efficacy of 68Ga-FAP-CHX.
To explore the value of 18F-fluorodeoxyglucose (FDG) PET/CT imaging in early diagnosis of treatment-related cardiotoxicity (TACT) of lymphoma using visual method and semi-quantitative method.
To evaluate the potential usefulness of 68Ga-FAP-2286 positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various types of cancer, and compared with 18F-FDG PET/CT.
The aim of this study is to compare the diagnostic performance of 68Ga-FAPI-46 PET/CT and 18F-FDG PET/CT in primary and metastatic lesions of breast cancer and to reveal the best diagnostic imaging time of 68Ga-FAPI-46 PET/CT.
It is an open label observation clinical trial, all participants are chronic liver disease. The investigators deem to make a novel evaluate criteria to hepatic fibrosis. The point of the clinical trial is to evaluate the novel biomaker 18F-FAPI-04 by PET-CT scan in the evaluation of the hepatic fibrosis.
Primary aldosteronism is the most common cause of secondary hypertension. The two main types of primary aldosteronism are aldosteronoma(30%) and adrenal hyperplasia(60%). The gold standard that determines the diagnosis and treatment strategy of primary aldosteronism is adrenal vein sampling(AVS), but the success rate is only about 80%. Using CXCR4 as a probe for 68Ga-Pentixafor PET/CT imaging can guide the classification diagnosis and treatment strategy of primary aldosteronism, which is a favorable supplement to AVS. Superselective adrenal artery embolization(SAAE) and laparoscopy are the main operation treatments for primary aldosteronism. SAAE is an invasive interventional operation. It is a novel way to evaluate the changes in the structure and function of adrenal tissue pre-postoperative SAAE by using the changes in 68Ga-Pentixafor PET/CT imaging.
