Tissue quality◦ Representative ◦ One large piece of tissue ◦ No artifacts
Patient comfort◦ No pain, no complication risk = safe
Inexpensive Access
◦ Handsome◦ Fast – minimal personnel◦ No dedicated room
Requirements for tissue acquistion related to translational research

Fine needle aspiration (Cytology)
Microbiopsy (16 to 14 Gauge)
Macrobiopsy (8 to 12 Gauge)
Open biopsy (general anaesthesia)

Representativity 98 % complete true prediction rate (compared to surgery)
False negative prediction rate < 1 %Transplantation quality150 to 300 mg samples
Patient comfort No pain (compared to mammography)No complications (requiring additional medical interventions)
Reduced scarringCosts Range 10 – 150 Euro (compared to 250 to 350 Euro)
Access Kits ready to start (compared to set-up times of > 30 min)
No decicated rooms
Results from safety and efficacy trials (n = 300 patients)
