摘要
目的探讨鼻咽癌常见的影像学表现,为临床上鉴别诊断鼻咽癌提供诊断依据。方法对42例鼻咽癌患者同时行鼻咽MRI和增强CT,2种检查均在20d内完成。比较这2种方法在诊断鼻咽癌超腔侵犯、咽后淋巴结转移、颅底骨质侵犯和颅内海绵窦侵犯上的检出例数及检出率。结果CT组和MRI组在超腔侵犯、咽后淋巴结转移、颅底骨质侵犯和颅内海绵窦侵犯上的检出例数及检出率分别为30例(71.4%)和36例(85.7%)、34例(80.9%)和38例(90.5%)、22例(52.4%)和35例(83.3%)、36例(85.7%)和38例(90.5%)。MRI表现出明显的优越性,在敏感度方面较增强CT有明显优势(P<0.05)。结论在2种影像学方法中,MRI较CT有明显优势,对初治鼻咽癌患者的判定更具价值。
Objective To explore the common imaging findings of nasopharyngeal carcinoma in order to provide the basis for diagnosis and differential diagnosis of nasopharyngeal carcinoma. Methods MRI and enhanced CT were performed in 42 patients of nasopharyngeal cancers within 20 days. Comparing the number of detected cases and detection rates of these two kinds of methods in the diagnosis of nasopharyngeal carcinoma in extra-cavity violation, retropharyngeal lymPh node metastasis, skull base invasion and intracranial cavernous infringement. Results The number of detected cases and the detection rate of CT group and MRI group in extra-cavity violation, retrophatyngeal lymph node metastasis, skull base invasion and intracranial cavernous infiingement were 30 cases （71.4%） and 36 cases （85.7%）, 34 cases （80.9%） and 38 cases （90.5%o）, 22 cases （52.4%） and 35 cases （83.3%）, 36 patients （85.7%） and 38 cases （90.5%）. MRI demonstrated a definite superiority to enhanced CT in sensitivity （P〈0.05）. Conclusion MRI has significant advantages over CT in the determination of previously untreated nasopharyngeal carcinoma.
