Implication

Caution against clinical use of ferucarbotran MRI for bone lesions; leaves open human validation from this rabbit model.

Structured PICO

Does ferucarbotran-enhanced MRI differentiate between bone metastasis and inflammation in a rabbit model?

P
Population
12 rabbits divided into tumor (n=6, inoculated with VX2 tumor cell suspension in the bone marrow of the right femur) and inflammation (n=6, inoculated with 10% croton oil in the bone marrow of the right femur) groups.
I
Intervention
Intravenous injection of 8 micromol Fe/kg of ferucarbotran.
C
Comparator
Comparison between tumor-inoculated right femur, inflammation-inoculated right femur, and normal intact left femur (control).
O
Outcome
Change in MRI signal intensity in the bone marrow before and after ferucarbotran injection.surrogate

Ferucarbotran-enhanced MRI can differentiate bone marrow tumors from inflammation in a rabbit model, as signal intensity decreases in inflammation but remains unchanged in tumors.
