Some patients with an established diagnosis of Crohn's disease and symptoms compatible with a disease flare do not have evidence of active Crohn's disease by laboratory, endoscopic or radiographic criteria. In clinical trials, approximately 18% of patients with Crohn's disease and moderate to severe clinical symptoms have no evidence of ulceration at colonoscopy. There are multiple other causes...

BACKGROUND Cross-sectional imaging modalities are fundamental in the management of patients with inflammatory bowel disease (IBD) from the first diagnosis and throughout the entire course of the disease. Over the past few years, the use of magnetic resonance (MR) imaging (MRI) has considerably increased, and no other imaging modality has experienced as advanced a development as MRI. METHODS A...

MR enterography (MRE) has become the primary imaging modality in the assessment of Crohn's disease (CD) in both children and adults at many institutions in the United States and worldwide, primarily due to its noninvasiveness, superior soft tissue contrast, and lack of ionizing radiation. MRE technique includes distention of the small bowel with oral contrast media with the acquisition of T2-we...

Video capsule endoscopy (VCE) has expanded the range of endoscopic examination of the small bowel. The clinical application of VCE is mainly for obscure gastrointestinal bleeding (OGIB) and small bowel tumor is one of the clinically significant diagnoses of VCE, often requiring subsequent invasive interventions. Small bowel tumors are detected with a frequency of around 4% with VCE in indicatio...

For the control of Crohn's disease (CD) a thorough assessment of the small intestine is essential; several modalities may be utilized, with cross-sectional imaging being important. Magnetic resonance (MR) enterography, i.e., MRE is recommended as a modality with the highest accuracy for CD lesions. MRE and MR enteroclysis are the two methods performed following distension of the small intestine...

Aim: The aim of this study was to investigate the efficacy magnetic resonance enterography (MRE) in diagnosis and follow-up Crohn’s Disease. Material Methot: Between November 2013 April 2014, patients who were MRE examinations for a preliminary or definitive Disease reviewed retrospectively. imaging performed on an 8-channel 1.5 Tesla MRI device. Primary secondary results contrast enhancement p...

background and aims. the imaging techniques commonly used for foreign body detection include plain radiography, xeroradiography, computed tomography (ct) scans, magnetic resonance imaging (mri) and ultrasonography. the aim of the present study was to compare cone-beam computed tomography (cbct) with conventional ct scan in determination of the exact location of a foreign body in the maxillofaci...

the c7-ras 6/061-004 training course by the international atomic energy agency/regional cooperative agreement (iaea/rca) was held in chiba in 2014. the syllabus, pre- and post-course evaluations, and survey questionnaire results were assembled in this course. the post-course evaluation, including 32 questions similar to the pre-course evaluation, was performed right after the end of the final e...

Magnetic resonance enterography (MRE) is fast becoming the first-line radiological investigation to evaluate the small bowel in patients with Crohn's disease. It can demonstrate both mural and extramural complications. The lack of ionizing radiation, together with high-contrast resolution, multiplanar capability and cine-imaging make it an attractive imaging modality in such patients who need p...
