Results
In our functional assessment using two MR modalities: DWI ( with ADC maps) and DCE-MRI we intentified 29 cases of active inflammation( with a presence of hyperenhancement of the wall and mural diffusion restriction),
15 of chronic (with mild or little wall enhancement and without restricted diffusion).
We also found 6 problematical cases: in 3 of them we found no radiological pathologies in MRI examination,
in 2 cases we noticed wall enhancement without diffusion restriction,
in 1 case restriction without a wall enhancement.
The ADC value was significantly lower in the active than in the chronic disease for both observed values of b parameter.
For b=50 it was 1,17±0,3 mm2/s ; p<0,001 in active and 2,13±0,1 mm2/s; p<0,002 in chronic inflammation.
For b=800 it was 0,98±0,1 mm2/s ; p<0,001 in active and 2,21±0,2mm2/s; p<0,001 in chronic inflammation.
We found no signicicant difference in results with a use of b=50 and b=800,
although because with b=800 we obtained lower ADC values in active disease we think it could be more useful in every-day practice.
