Objective To investigate the value of multi-slice spiral CT （MSCT） imaging technique in the diagnosis of intestinal Crohn＇s disease （CD）. Methods MSCT plain scan and enhanced scan data of 72 patients with pathologically confirmed CD in Suzhou Municipal Hospital North from July 2010 to April 2012 were retrospectively analysed. All cases did bowel cleaning and orally taken sufficient quantities of isotonic 2.5% mannitol solution in order to expand enterocoel fully before undergoing MSCT examination.Axial images of scan and enhancement and three-dimensional reconstruction images were acquired and observed. Results The lesions located at jejunum and rileum in 10 patients, ileum and colon in 15 patients, jileocecal valve in 26 patients ; 236 lesions were observed and distributed discontinuously. All lesions showed bowel wall thickening, mural stratification and circular thickening in 53 lesions, unilateral thickening in 82 lesions, multiple segmental mixed thickening in 101 lesions; luminal narrowing coexisted with bowel wall thickening; mucosa abnormal enhancement in mucosa in 225 lesions, and the degree of enhancement depended on disease activity; thickening and increasing of mesenteric vessel in 101 lesions, hickening and increasing of mesenteric lymph node in 91 lesions; 4 cases with incomplete obstruction and 2 cases with abscess formation. Conclusion MSCT combined with enhanced scan and reconstruction technique has high diagnostic value in lesion localization, judgement of activity degree and showing cmplications.
