T2 Relaxation time study of the pig renal allografts

A previous study showed the possibility of the dependence of theT₂ maps measured by Siemens Magnetom MR imager 1.5 T on the viability of the cadaveric kidney. For theT₂ relaxometry study the pig model was used. Ten pig renal allografts were examined during 68 h after removal. Significant differences were found in the change of the initialT₂ⁱⁿⁱ values in the histogram within the first 20 h [₁=T₂ⁱⁿⁱ (2)–T₂ⁱⁿⁱ (20)] or 8 h [₂=T₂ⁱⁿⁱ (2)–T₂ⁿⁱ (8)] after removal between the groups of the damaged kidneys (₁=20.2±6.8 ms, ₂=19.4±3.0) and the kidneys without apparent damage (₁=9.4±8.5 ms, ₂=5.4±5.8).
