Method | Definition principle | Advantage | Disadvantage | Clinical application |
DWI | Detection of diffusion of water molecules in living tissue | No contrast agent; High sensitivity; Easy to operate; | Low image resolution; Low specificity | Most basic and widely used |
DCE-MRI | Evaluation of breast tumor angiogenesis | High sensitivity, accuracy and specificity; Quantitative judgment | Complex to operate; | Most basic and widely used |
MRS | Study changes in tumor metabolite content | analyze metabolites; Quantitative assessment of lipid metabolism | Longer imaging time; Quantification of choline concentration is difficult to standardize | Frequently used |
PWI | Reflecting microvascular distribution and blood perfusion status of breast tissue | Reflect microvascular distribution and blood perfusion status; Higher diagnostic specificity | Low sensitivity; Heterogeneity in blood perfusion; | Less used |
PET/MRI
| A system of functional imaging and structural imaging at the molecular level | Functional imaging at the molecular level; High sensitivity, accuracy and specificity; | Complex to operate; Less technicians and diagnosticians; Radioactivity expensive | Rarely used |
Mammography imaging and imaging genomics | Studying the link between breast cancer genomic features and imaging features | Create a high-dimensional data set; Using image features to reflect gene activity | Too small sample size; Clinically practical is not strong | Used only for academic research |
