Wall thickness that measures greater than 3mm is abnormal; this thickening is due to edema and inflammation, which result in slightly increased signal intensity on T2-weighted HASTE and TrueFISP images. FCP levels, MaRIA, and CDEIS are highly correlated with positive and significant Pearson and Spearman coefficients, respectively (P<0.0001), in univariate analyses. The choice between modalities is largely one of availability, experience and institutional or individual Obstructive symptoms due to adhesions, inflammatory narrowing or fibrosis are common.
