“…It would have been interesting to compare the accuracy of US with that of MRI, CT or scintigraphy using different wall thickness thresholds, but the analysis of these subgroups was possible only for US, as up to this point, only scanty data are available for the other techniques. Furthermore, Pan es et al ( 2011) reviewed 68 primary studies, 5 of which (Astegiano et al 2001;Borthne et al 2006;Bozkurt et al 1994;Hollerbach et al 1998;Parente et al 2003) assessed the role of US in the diagnosis of CD. Again, in that review, BWT was the main imaging parameter used for identification of CD, and the cutoff value considered for a positive finding was $4 mm.…”

“…The overall per-patient sensitivity and specificity of US were 85% (95% CI: 83%-87%) and 98% (95% CI: 95%-99%), respectively, with a moderate heterogeneity among the degrees of sensitivity reported in the studies, partly attributable to the different cutoff values used for BWT and operators' experience, but overall the results indicated that US can be considered an accurate technique to detect bowel wall abnormalities, with a derived LR1 of 42.5 and LR2 of 0.15, confirming the relevant role of US as a CD diagnostic test. Among all the studies included in the meta-analysis by Pan es et al ( 2011), the only direct comparison of the diagnostic accuracy of cross-sectional imaging techniques, in particular US and MRI, using ileocolonoscopy as the reference standard, was performed on a pediatric population with suspected IBD by Borthne et al (2006), who reported that US had a higher sensitivity than MRI (93% vs. 82%). However, the sample size of their study was very small, and only CD of the terminal ileum was considered, this being already known as the site with the highest accuracy for US in the detection of CD (Fraquelli et al 2005 Recently, a direct comparison of different imaging techniques was carried out by Castiglione et al (2013).…”

Crohn's disease (CD) is an inflammatory chronic bowel disorder; it can involve the whole gastrointestinal tract, but its localization in the ileum or colon is most common. The reference standard for the diagnosis of CD is ileocolonoscopy with histologic assessment. The reference standard for the detection of any complications is surgery. However, imaging techniques have an important role both in the detection/localization of CD and in the follow-up of CD patients. In the last few years, the technical development of ultrasound equipment, the advent of new technologies such as elastography and mostly the increased expertise of sonographers have boosted the role of bowel ultrasound in assessment of the gastrointestinal tract. In fact, bowel ultrasound is particularly attractive thanks to its widespread availability, non-invasiveness, low cost and good reproducibility, as it can be easily repeated during follow-up. The aim of this article is to provide an extensive overview of the actual role of bowel ultrasound in the detection and follow-up of patients with CD.

Double-contrast magnetic resonance imaging of the small and large bowel: effectiveness in the evaluation of inflammatory bowel disease

Double-contrast magnetic resonance imaging (DC-MRI) is a technique for imaging the intestine, which has shown to be very effective in assessing inflammatory bowel disease (IBD), and particularly Crohn's disease (CD). The expression derives from the association of two different contrast agents, a superparmagnetic intestinal and a paramagnetic intravenous contrast agent. This specific contrast media combination provides optimization of the tissue contrast, both on T1- and T2-weighted images, thus allowing an effective display of small and large bowel loops in normal and pathologic conditions. Therefore, main CD complications (strictures, fistulas, and abscesses), as well as disease activity, may be valuably assessed. The term DC-MRI may also be referred to the typical "double contrast" effect that is produced by this technique at the level of the inflamed bowel wall, both on T1- and T2-weighted images, directly related to the degree of wall inflammation (disease activity).
