Appendicitis Diagnosis and Management

The role of radiologic evaluation in Crohn's disease (CD) has undergone a recent paradigm shift in which the radiologist adds value to the multidisciplinary team by longitudinally assessing therapeutic response and identifying treatment-modifying subtypes, such as fibrostenotic or fistulizing disease. Magnetic resonance enterography (MRE) has become the primary imaging modality used. The combination of multiplanar, multiparametric, and multiphasic contrast-enhanced imaging with the high spatial resolution and very high tissue contrast of MR imaging allows for detailed evaluation of intra-abdominal pathology, without the risk of cumulative radiation exposure. MRE provides the benefit of a complete evaluation of mural, extramural, and even extraintestinal manifestations and complications of CD in a single examination. Cine motility sequences and diffusion-weighted imaging may further increase sensitivity and specificity. MRE represents an ideal imaging modality for initial evaluation, assessment of therapeutic response, and evaluation of complications in patients with CD.
