| [ Summary ] | The role of cross-sectional imaging such as CTs or MRIs includes detection, characterization, analysis of the relationship between mass and surrounding organs, recognition of signs of malignancy and evaluation of treatment effects. CT is the most commonly used diagnostic tool for SMT. MRIs are the best investigative modality for soft tissue characterization, allowing the assessment of rectal lesions at present. Evaluation of tumor extension and metastatic disease is relatively easy. However, detection of small lesions or making differential diagnoses can present a challenge when employing routine abdominal CTs. Recent, developments in imaging technology have led to many improvements in the field of diagnostic GI radiology. As part of this trend, multiplanar reconstruction images from CT enterography have become an effective and non-invasive tool for evaluation of small intestine SMT. | |
