Low-radiation dose CT to study Crohn's disease

摘要

CT has been recognized as an accurate tool for evaluating both intestinal and extraintestinal Crohn's disease (CD) complications in the abdomen and pelvis. However, there are some concerns regarding the potential long-term effects of repeated exposure to ionizing radiation from CT scans. Therefore, the use of other nonionizing radiation-based cross-sectional imaging modalities have been introduced especially for those CD patients who undergo repeated imaging studies.
