Magnetic resonance imaging of the small bowel with the true FISP sequence: intra- and interobserver agreement of enteroclysis and imaging without contrast material.

Purpose: This study aimed to determine the reliability of magnetic resonance imaging (MRI) without luminal contrast medium versus MR enteroclysis for evaluating small bowel pathology, to compare MRI and MRE findings per observer, and to compare these findings with those of an expert reader in order to determine the influence of luminal contrast medium on morphological evaluations.

Conclusion: The use of luminal contrast medium bowel improves reliability for measuring bowel wall thickness and for the diagnosis and grading of obstruction when evaluating the small bowel.

A patient with endobronchial BALT lymphoma successfully treated with radiotherapy.

Low-grade bronchus-associated lymphoid tissue (BALT) lymphoma is a rare tumour originating from the marginal zone of lymphoid tissue. It is a subgroup of B-cell extranodal non-Hodgkin's lymphoma with an indolent course. We report a case of this tumour with characteristic histologic feature.

MR Enteroclysis of inflammatory small-bowel diseases.

Objective: MR enteroclysis has been introduced in the workup of small-bowel diseases. The major advantage of this technique over others is the combined visualization of luminal, mural, and extramural abnormalities. In this article we propose an MR enteroclysis protocol, present a stepwise approach for evaluation of these examinations, and discuss the different inflammatory conditions that can be detected.
