| Popis: | A previous study showed the possibility of the dependence of theT 2 maps measured by Siemens Magnetom MR imager 1.5 T on the viability of the cadaveric kidney. For theT 2 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 initialT 2 ini values in the histogram within the first 20 h [σ1=T 2 ini (2)−T 2 ini (20)] or 8 h [σ2=T 2 ini (2)−T 2 ni (8)] after removal between the groups of the damaged kidneys (σ1=20.2±6.8 ms, σ2=19.4±3.0) and the kidneys without apparent damage (σ1=9.4±8.5 ms, σ2=5.4±5.8). |
