The purpose of this study is:
To validate the efficacy of multiparametric MRI, FDG-PET, RGD-PET, and PET-MR fusion imaging in the prediction and monitoring response to neoadjuvant chemotherapy of locally advanced breast cancer patients.
To identify the optimal combination parameters of MR spectroscopy, diffusion-weighted MRI, dynamic contrast-enhanced MRI, FDG-PET, and RGD-PET in the prediction and monitoring response to neoadjuvant chemotherapy of locally advanced breast cancer patients.
To compare the performances of dynamic contrast-enhanced MRI using parametric response map analysis versus those of pharmacokinetic parameters (Ktrans, kep, or Ve) in the early prediction of pathological responsiveness to neoadjuvant chemotherapy in breast cancer patients

- Patholocial Response to Chemotherapy [ Time Frame: Post-operation ]Pathological complete response (pCR) or non-pCR
- Tumor Size [ Time Frame: baseline, completion of 1st cycle of chemotherapy ]Maximal tumor diameter measured on magnetic resonance imaging
- Tumor Volume [ Time Frame: Baseline, post-1st chemotherapy ]Tumor volume measured on 3-dimensional magnetic resonance imaging
- Proportions of Voxels Within a Tumor With Increased or Decreased Signal Intensity (Parametric Response Map Signal Intensity; PRMSI) [ Time Frame: Baseline, post-1st chemotherapy ]Parametric response map analysis using a software calculates the interval change of signal intensity based on a voxel-to-voxel comparison between measurements at baseline and after the first cycle of chemotherapy. PRMSI+ indicates proportions of voxels within a tumor with increased signal intensity. PRMSI- indicates proportions of voxels within a tumor with decreased signal intensity. PRMSI0 indicates proportions of voxels within a tumor with unchanged signal intensity.
- Constant for the Transfer of the Contrast Agent From the Plasma Compartment Into the Extracellular Extravascular Space (Ktrans) [ Time Frame: Baseline, post-1st chemotherapy ]
- Rate Constant of the Escape of the Contrast Agent From the Extracellular Extravascular Space Into the Plasma Compartment (Kep) [ Time Frame: Baseline, post-1st chemotherapy ]
- Extracellular Extravascular Space Per Unit Volume of Tissue (Ve) [ Time Frame: Baseline, post-1st chemotherapy ]
- Total Choline Amount of the Tumor Measured on Single Voxel 1H-magnetic Resonance Spectroscopy [ Time Frame: Baseline, post-1st chemotherapy ]Single voxel 1H-magnetic resonance spectroscopy quantifies the amount of total choline-containing compounds of a tumor, which indicates cellular proliferation and malignant transformation.
- Standardized Uptake Value on 18F-fluoro-deoxy-glucose Positron Emission Tomography [ Time Frame: Baseline, post-1st chemotherapy ]
