MRI to Assess Fibrosis in Eosinophilic Esophagitis Patients — EoE  

Eosinophilic Esophagitis Clinical Trial

Official title:
Assessment of Fibrotic and Inflammatory Components by MRI in Strictures Associated With Eosinophilic Esophagitis Before and After Treatment

Clinical Trial Summary

Can an MRI detect and monitor the inflammatory and fibrotic possess in patients with Eosinophilic Esophagitis

Clinical Trial Description

MRI will be performed on a 1.5T magnet. Patients will be scanned in an oblique prone position similar to how esophageal distention is assessed at barium fluoroscopy. The following sequences and rationale will be used for the examination: A sagittal 50mm thick multiphase FIESTA and multiphase SSFSE will be performed while the patient drinks water. The temporal resolution of the images will be approximately 1 image every 1.5-2 seconds. The images will be used to assess the lumen caliber and the wall thickness during maximal distension as pseudothickening can occur with decreased luminal distension. Sagittal SSFSE with fat suppression, sagittal FRFSE T2-weighted images with fat suppression, axial DWI and sagittal DWI will be performed to asses for edema and inflammation within the esophageal wall. axial FS SSFSE or FIESTA will be performed and targeted to the region of stricturing. Dynamic sagittal imaging will be performed following IV contrast to assess for mural hyperenhancement which can be seen mural inflammation and delayed enhancement which can be seen in fibrosis. Sequential acquisitions will be performed beginning at 40 seconds following IV contrast injection. Delayed acquisitions will be performed at 5 min and 7 min. Patients will be asked to perform swallowing during the image acquisition to reduce the potential for pseudoenhancement secondary to under distension. ;
