多层螺旋CT多平面重建技术在阑尾炎诊断中的应用 postprint

Abstract: Objective To explore the diagnostic value of multiplanar reconstruction (MPR) with multi-slice spiral CT onappendicitis. Methods Fifty-five patients with clinical suspected acute appendicitis were enrolled. 16-slice spiral CT was usedto scan and manage multi planar volume recombination images. The CT images were retrospectively analyzed. The rates ofsigns in the diagnosis of acute appendicitis were expored by comparing the reconstructed image with the reconstructed image.Results The diagnosis of acute appendicitis was performed in 50 patients with pathologically confirmed appendicitis. Rightovarian cyst, calculi within distal segment of right ureter, cholecystitis, colon tumor, pelvic inflammatory disease wereperformed in 1 patient for each. The discrimination rate of appendix, detection rate of appendix wall thickening and ileocecumwall thickening in reconstruction image were higher than that in unreconstruction image (P<0.05). Conclusion Multi-slice CTin combination with MPR can improve the diagnosis accuracy for acute appendicitis. It is fast and accurate in the diagnosis ofappendicitis and other diseases, which is worthy of clinical application.
