目的:探讨腺样体肥大的螺旋CT诊断价值及CT斜冠状位重组图像在判断样体肥大程度的应用。方法:分析28例腺样体肥大的CT表现,在斜冠状位重组图像进行A/N比值测量。结果:腺样体肥大的CT表现为鼻咽顶后壁中央的软组织增生,引起鼻咽腔狭窄。结论:斜冠状位重组图像进行A/N比值测量能准确地诊断腺样体肥大,判断腺样体肥大程度,明确并发症。
Objective: To investigate the diagnostic value of helical CT in adenoid hypertrophy and the application of CT oblique coronal recombination to determine the extent of sample hypertrophy. Methods: CT findings of 28 cases of adenoid hypertrophy were analyzed. A / N ratio was measured in the oblique coronal images. Results: Adenoid hypertrophy of CT showed nasal pharyngeal posterior wall of the central soft tissue proliferation, causing nasopharyngeal stenosis. Conclusion: A / N ratio measurement of the oblique coronal images can accurately diagnose adenoid hypertrophy, determine the degree of adenoid hypertrophy, and confirm the complication.
