Department of Radiology，the PLA Military 175 Hospital，Hangzhou 363000，China [Abstract] Objective To evaluate the value of multi-row detector CT for diagnosis of qualifying and localizing bezoar small bowel obstruction．Methods Multi-row detector CT（MDCT） features and clinical materials of bezoar small bowel obstruction in 9 cases which confirmed by surgery were retrospectively analyzed. Results The diagnostic accuracy in localizing intestinal obstruction with MDCT was 100％，5 cases located in middle jejunum ，3 cases in the junction of jejunum and ileum and 1 cases in terminal ileum；Nine cases（100％）were diagnosed qualitatively．The main CT findings were as follows：capsule-like high deity margin （9/9，100%），the honeycomb-like air bubble shadows in the lesio（9/9，100％），target sign in the adjacent proximal intestinal walls enhanced on contrast enhanced images（8/9，%）， peribowels fatty tissue blur，fluidify sign（6/9，%）. Conclusion Multi-row detector CT plays an important role for qualifying and localizing diagnosis of bezoar small bowel obstruction before operation.
