Abstract:
Objective To discuss the application value of MSCT in the diagnosis of acute appendicitis.Methods 30 patients with appendicitis were enrolled as a research group,meanwhile 30 healthy adults without any diseases were as a control group.Some MSCT findings were observed or measured including diameter and position of appendix,fluid and gas density in appendix cavity, periappendicural fat density and peritoneal thickening,ascites and so on.Results The outside diameter of acute appendicitis appen-dix was (9.78±2.33)mm on average,whereas the diameter of normal adults appendix was (5.05±0.53)mm,exhibiting a signifi-cant difference (t=24.85,P <0.01).Rough periappendicural fat with increased density in 25 patients (83.33%)with the CT value of about -40 to 20 HU,exudation and peritoneal thickening around the appendix in 13 (43.33%),thickening and edematous appen-dix walls in 29 (96.67%),fecal stone in the appendix cavity with high density in 9(30.00%),the appendicitis in combination with intestinal obstruction in 1 (3.33%),and the appendicitis with peritoneal thickening in 80.00% and with peritoneal effusion in 23.33%were found in the study.Conclusion Full abdominal MSCT can help to the diagnosis of acute appendicitis,and some MSCT findings can be useful for the diagnosis including the appendix diameter≥6 mm,appendix cavity effusion,lumen stone,peripheral increased adipose density and peritoneal effusion.
