To retrospectively analyze the advantages and disadvantages of imaging methods commonly used for diagnosis of gland submandibular diseases.
One hundred and eighty-two patients with submandibular gland surgery were retrospectively studied to compare the accuracy rate between preoperative imaging and postoperative diagnosis.The data were analyzed using SAS8.0 software package.Fisher's exact test was used to compare the difference between B type ultrasonography, CT and MRI.
Compared with postoperative pathological results,diagnostic accuracy rate of B type ultrasonography, CT and X-ray was 85.34%, 79.66% and 92.31%, respectively. MRI had a higher accuracy rate than B type ultrasonography or CT.(P<0.05).
B type ultrasonography, CT and X-ray examination have misdiagnosis especially in submandibular sialadenitis,which is one of the most important causes of misdiagnosis leading to excision of the glands.MRI has higher application value in diagnosis of submandibular gland diseases.
回顾性分析常用于诊断颌下腺疾病的影像学方法的优缺点。
回顾性研究182例行颌下腺手术的患者，比较术前影像学检查与术后诊断的准确率。数据采用SAS8.0软件包进行分析。采用Fisher确切概率法比较B型超声、CT和MRI之间的差异。
与术后病理结果相比，B型超声、CT和X线的诊断准确率分别为85.34%、79.66%和92.31%。MRI的准确率高于B型超声或CT（P<0.05）。
B型超声、CT和X线检查存在误诊情况，尤其是在颌下腺炎中，这是导致腺体切除的重要误诊原因之一。MRI在颌下腺疾病的诊断中具有较高的应用价值。
