Magnetic Resonance Enterography (MRE): The role of imaging in the management of adult patients with Crohn's disease.

Crohn's disease, an inflammatory bowel disease with devastating complications, often requires frequent imaging to detect active disease and its complications. Endoscopy, which is the gold standard for diagnosis, is contraindicated in come patients and has limited role in detecting deep submucosal/mesenteric disease, mid small bowel disease and intra-abdominal complications. Magnetic Resonance Enterography (MRE) has evolved as a complimentary non-invasive, radiation free, high resolution imaging modality in evaluating these patients, with clinical studies haveing shown MRE to help in the diagnosis and follow up of these patients. Its major advantage over CT Enterography is the absence of radiation.

Magnetic Resonance Imaging of Nonneoplastic Musculoskeletal Pathologies in the Pelvis.

Musculoskeletal pathologies in the pelvis encompass a wide variety of lesions including femoroacetabular impingement, athletic pubalgia, ischiofemoral impingement, and apophyseal avulsion injuries. Magnetic resonance imaging is the noninvasive imaging modality of choice for the diagnosis and management of these lesions. In this article, the authors discuss the nonneoplastic musculoskeletal lesions in the pelvis, with illustrations and relevant case examples.

Magnetic resonance enterography: A stepwise interpretation approach and role of imaging in management of adult Crohn's disease.

Crohn's disease (CD) is a chronic inflammatory bowel disease that often requires frequent imaging of patients in order to detect active disease and other complications related to disease activity. While endoscopy is the gold standard for diagnosis, it may be contraindicated in some patients and has a limited role in detecting deep submucosal/mesenteric diseases and intra abdominal complications. In recent years, magnetic resonance enterography (MRE) has evolved as a noninvasive, radiation free imaging modality in the evaluation of patients with CD. This review article will focus on role of MRE in imaging patients with CD with emphasis on technical considerations, systematic image interpretation, differential diagnoses, and the role of imaging in deciding treatment options for patients.

Imaging of Sarcoidosis: A Contemporary Review.

Sarcoidosis is a systemic granulomatous disorder with a variety of clinical presentations and radiological appearances. Although it primarily affects the lungs and lymphatics, sarcoidosis potentially involves essentially every organ system. On imaging, sarcoidosis can mimic different disease entities, including primary and metastatic neoplasms, vasculitis, and other granulomatous infections. Definitive diagnosis often requires a combination of clinical, radiological, and histologic information. Imaging plays a crucial role in diagnosis and evaluating response to therapy. This review covers imaging findings in sarcoidosis within each organ system, with an emphasis on the use of imaging in the diagnosis and management of this condition.
