Thus, the main goal of our study was to evaluate the role of US/SE itself and in comparison to E-MRI in the differentiation of fibrotic and edematous pattern of CD.
A strength of our evaluation is surely the performance of SE soon after E-MRI, and thus the effect of the spasmolytic agent may have helped in the evaluation of the bowel wall and mesentery stiffness.

In another, involving 53 patients with RA, 25 with arthralgia, and 25 with other rheumatic diseases, e-MRI detected 496 erosions, compared with 379 for whole-body MRI.
A third study, involving 37 patients with RA and 28 normal patients, determined that e-MRI had a 94% sensitivity, 93% specificity, and a 94% accuracy, compared with whole-body MRI in detecting erosions (Ann.
In detecting synovitis, the study findings indicated a 90% sensitivity, a 96% specificity, and a 94% accuracy for e-MRI. But the investigators used gadolinium as a contrast agent, something few office-based rheumatologists are equipped to do.
E-MRI doesn't do as well in the detection of bone edema.
Several studies show that intra- and interrater reliability for e-MRI ranged from good to very good, but the studies all used experienced readers.
E-MRI also performs well on sensitivity to erosion change--with one study, as yet unpublished, showing that e-MRI has more than twice the sensitivity to change than x-rays alone.
