2. Advantages of radio-tracer than Hook-wire
3D localization by assistance of C-arm
Immediate assessment of margin distance
Can be performed one day before operation
Dislocation never happens
Absolute bed rest is not necessary

3. Barium vs. Lipiodol Barium Lipiodol Thick, viscous Fat emulsion
Palpable
Usually not palpable
Low cost
High cost
Not aseptic preparation
Aseptic preparation
Macrophage accumulation
Relatively low tissue reaction
Low risk of embolization
Embolization risk?
