Brief Summary
The investigators aim to develop an advanced imaging platform, such as dynamic nuclear polarization (DNP) 13C-MRI, MR fingerprinting (MRF) and MR Relaxometry, which combines with traditional anatomical contrast CT, MRI and PET, and integrate blood/urine metabolomics methods. A comprehensive strategy to thoroughly analyze the immune activation of spleen pattern, microstructure, cell density, red blood cell iron content, immune cell glycolysis and metabolic flow rate.

Interventions
DNP-MRI for splenic immune function evaluation through hyperpolarized 13C-Pyruvate injection
Eligibility Criteria
You may qualify if:
- Newly diagnosed or recurrent gynecological cancer confirmed by histology.
- Age ≥ 20 years old.
- Expected to receive immunotherapy.
You may not qualify if:
- Suffering from other malignancies (excluding non-melanoma skin cancer).
- History of splenic abnormalities (such as splenic damage, cirrhosis-related splenomegaly or primary/metastatic splenic tumors).
- Insufficient function of bone marrow, liver and kidney.
- Contraindications to MRI studies (e.g. claustrophobia, cardiac pacemaker, metal implants in the pelvis).
- Uncontrolled concurrent diseases, including but not limited to kidney stones, persistent or active infection, symptomatic heart failure, unstable angina, cardiac arrhythmias, or mental illness/social situations that limit compliance with research requirements.
- Pregnant or lactating women.
