A Study of [68Ga]Ga-NOTA-RG2 PET Imaging in the Diagnosis of Hepatocellular Carcinoma

Study Overview
=================
Brief Summary
-----------------
The aim of this study was to establish and optimize the imaging method of [68Ga]Ga-NOTA-RG2, as well as its physiological and pathological distribution characteristics, and on this basis to evaluate the diagnostic efficacy of the above imaging agents in patients with hepatocellular carcinoma.

Official Title
-----------------
A Study of [68Ga]Ga-NOTA-RG2 PET Imaging in the Diagnosis of Hepatocellular

Conditions
-----------------
Hepatocellular Carcinoma

Intervention / Treatment
-----------------
* Radiation: [68Ga]Ga-NOTA-RG2 PET Imaging


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Hepatocellular carcinoma patients Age between 18 and 65 years old, gender is not limited. Patients with suspicious intrahepatic spaces detected by MR and considered to be hepatocellular carcinoma with AFP>200 ug/L who have not undergone surgery. Patients with hepatocellular carcinoma confirmed by puncture pathology Written informed consent must be signed by the subject or his/her legal guardian or caregiver. Willingness and ability to cooperate with all programs of the study. Exclusion Criteria: Subjects meeting any of the following criteria will be excluded from the study: Patients receiving anti-tumor therapy prior to the PET/CT scan. Suffering from severe other neurological disorders, or gastrointestinal, cardiovascular, hepatic, renal, hematologic, respiratory, immunodeficiency, and other serious diseases. Alternative subjects with conditions that contraindicate PET/CT scanning. This includes, but is not limited to, elevated blood glucose that is not effectively controlled; pregnant, lactating, or breastfeeding women; those who are unable to receive repeated intravenous injections; those who may be hypersensitive to the drug and its components (including a history of severe allergies or anaphylactic reactions, especially to the drug being examined); and hermetic phobias. Within the past year, have participated in other research protocols or clinical care, in addition to the radiation exposure expected from participation in this clinical study, which has resulted in radiation exposure in excess of an effective dose of 50 mSv. Alternative subjects have undergone major surgery within the last 3 months; experimental drug or device therapy (of uncertain efficacy or safety) within 1 month The alternate subject has any clinical condition that, in the opinion of the Sponsor of this study, may cause or has the potential to cause harm from this agent.
