Learning objectives To review the main imaging techniques in the setting of Crohn’s disease (CD), their indications and adequate protocols for a sustainable approach, their specificities, and patient preparation. Furthermore, we aim to point out the steps of the systematic analysis of these exams and to help the radiologist in charge orient the clinician towards the predominance of active inflammation or fibrosis.
Read more Background CD is a chronic inflammatory condition affecting the gastrointestinal tract, necessitating precise imaging techniques for a thorough diagnosis, management, and monitoring of disease activity. This review examines imaging techniques like MRI, CT, and ultrasound for managing CD with real-life examples from eight patients from Centre Hospitalier d’Arras (France).
Read more Findings and procedure details CD has a bimodal age distribution [1], with two age peaks at 20-40 years old (but some patients are diagnosed even before the age of 10) and 60-70 years old. Therefore, age cannot eliminate CD.The diagnosis is based on a comprehensive analysis of several aspects, such as the patient’s symptoms, faecal calprotectin level, endoscopic studies (limited to the endoluminal involvement), histopathological analysis, and the presence of specific antibodies (positive ASCA antibodies) [2]. [fig 1] The imaging studies have several roles: to assess...
Read more Conclusion Appropriate selection and application of imaging modalities, along with systematic analysis, significantly improve the diagnostic accuracy and patient management in CD on one hand and the sustainability of medical imaging on the other hand. MRI and CT can effectively delineate active inflammation from fibrosis and detect complications. [fig 20]
