Fluorocholine PET/MR in Breast Cancer

Objectives: Our study is conducted to use the pre-treatment Fluorocholine (FCH) Positron emission tomography/magnetic resonance (PET/MR) imaging in breast cancer patients, to investigate whether the conventional PET/MR imaging markers (maximum standardized uptake value \[SUVmax\], MR spectroscopy-derived choline analysis, dynamic contrast-enhanced MRI, apparent diffusion coefficient \[ADC\] analysis), and FCH PET/MR radiomic features, deep learning (DL) analysis are associated with molecular subtypes, clinical outcomes, treatment response, survival, and which parameters are more accurate for predictive purposes. Primary study purposes: -To investigate whether the pre-treatment FCH PET/MR imaging parameters are associated with molecular subtypes of breast cancers, and to evaluate the diagnostic performance for predictive purposes. Secondary study purposes: -To investigate whether the pre-treatment FCH PET/MR imaging parameters are associated with the factors related to clinical outcomes (histologic grade, prognosis) and to analyze which parameters are more accurate for predictive purposes. Test drug: Name: 18F- Fluorocholine (18F-FCH) Dosage form: N-(\[18F\]fluoromethyl)-2-hydroxy-N,N-dimethylethan-1-aminium Strength: 3-5 MBq/kg per patient (5-6 mCi/mL at time of injection (TOI)) Dosage and administration: Intravenous injection.fluoromethyl Selection criteria: 1. Women aged 25-75 years old. 2. Women diagnosed with breast cancer by pathological diagnosis from a core bio…
