As for as motility,
we observed lack of Peristalsis in 23 Active and in 2 Inactive cases, lack of Distensibility in 27 Active and 7 Inactive cases and presence of Retrodilation in 5 Active and 2 Inactive patients.
On DWI,
Inflammatory bowel tracts showed higher signal intensity compared to normal segments (Accuracy: 89,1%,
Sensitivity: 89,7%,
Specificity: 88,2%,
PPV: 92,9%,
NPV: 83,3). In quantitative assessment,
ADC value in active disease was lower than in inactive disease (Negative: 1,9 x 10-3 ± 0,3 x 10-3 mm2/s,
Inactive: 1,38 x 10-3± 0,26 x 10-3 mm2/s,
Active: 1,08 x 10-3 ± 0,22 x 10-3 mm2/s).
DWI evaluation alone provided 2 False Active results and 3 False Inactive patients with respect to C-DE-MRI evaluation,
but correcting with ADC map evaluation,
basal study showed a performance similar to C-DE-MRI.
Comprehensive MR examination allowed a detailed and panoramic evaluation of the small bowel in all subjects,
in terms of:
- Wall thickness
- Luminal stenosis
- Dynamic wall enhancement
- Peristalsis and Distensibility
- Mesenteric involvement
-Pathologic lymph nodes
-Sinus tracts-fistulae
-Inflammatory masses
