Abstract:
Objective To summarize MSCT manifestations of normal small bowel with oral water and colon water enema double-filling. Methods Small bowel parameters of 44 healthy volunteers were measured with oral water and colon water enema double-filling. The parameters included bowel wall thickness, diameter of filling bowel, bowel wall delamination, bowel wall CT attenuation, the number of the plica, the attenuation of mesenteric fat, mesenteric vessels, the appearance rate of lymph node in mesentery, retroperitoneum, and so on. Results The average bowel thickness was (1.72±0.20) mm; the average diameter of filling bowel was (21.24±3.05) mm; the average CT attenuation of plain scan, artery phase and portal phase was (28.13±0.38) HU, (55.42±0.88) HU and (67.86±0.94) HU. Jejunum plica of normal small intestine was 2.29/cm; the number of the mesenteric artery bowel was 2.59/cm; the average attenuation of mesenteric fat was-98.57 HU; the single layer of bowel changed mostly. Conclusion Proper knowledge of normal manifestations of small bowel on MSCT is helpful for the diagnosis of small bowel diseases.
