Advantages and Disadvantages of In Ovo Imaging with Ostrich Eggs

High availability (no dedicated small-animal imaging device necessary)Higher cost per ostrich egg (€20–130 [$23–$151]) than per chicken eggs
Low costs for equipment, premises, and personnel (if clinical scanner used for humans is available on site)Shorter availability of ostrich eggs (March–September) than of chicken eggs
No need for mouse or rat husbandryLower spatial resolution than for dedicated small-animal devices
Not considered animal testing, simplifying study design planningRestricted experimentation time (afternoon or evening, after all patients have been examined)
Larger organ size than for chicken embryos
Lower radiation exposure than for small-animal CT devices
Shorter acquisition and higher temporal resolution than for flat-panel small-animal CT devices
