The significance of multi-slice helical CT multiplanar reconstruction in the diagnoses of laryngeal carcinoma / 中华放射学杂志

ABSTRACT

Objective To evaluate the significance of multi-slice helical CT with multiplanar reconstruction in laryngeal carcinoma.Methods Thirty-five patients with laryngeal carcinoma were studied by helical CT,MPR were subsequently done.The lesion extent of the axial image findings,MPR findings and the combined image findings were compared with the pathological results respectively.The data were statistically analyzed.Results In the evaluation of the anterior commissure,the axial image findings,MPR findings and the combined image findings were 82.9%,68.6% and 91.4% in accuracy respectively,the results were statistically different(P0.05).The combined images were superior to the axial images and the MPR images in sensitivity,specificity and accuracy of the lesion extent.Conclusion The axial images could show the shape,size,extension of the tumor and the lymphadenopathy,MPR images displayed the shape,size and extension roundly and directly,they were the supplement for the axial images.Axial images combined with MPR could improve the accuracy in the diagnoses of laryngeal carcinoma.
