７８ 例颌下腺肿瘤造影诊断和术后病理分析，其中良性肿瘤４１ 例，恶性肿瘤３７ 例，主要分析肿瘤在颌下腺的主导管、分支导管、腺泡压迫侵犯的造影片表现。结果良恶性肿瘤鉴别，主要区分在恶性肿瘤导管、腺泡有不同程度的破坏，造影片显示主导管中断、腺泡不同程度破坏，造影剂外溢。在诊断中应排除假阳性率，如造影剂注射多与少，良性肿瘤较大压迫导管产生中断，结核、长期慢性炎症的导管腺泡可产生中断和破坏等。诊断符合率良性肿瘤９０ ．２ ％ ，恶性肿瘤７０ ．２ ％ ，颌下腺造影在肿瘤治疗前的诊断有很重要的参考价值。
78 cases of submandibular gland tumor angiography diagnosis and postoperative pathological analysis, including 41 cases of benign tumors, 37 cases of malignant tumors, the main analysis of the tumor in the submandibular gland of the main duct, branch duct, acinar compression of the performance of the film. The results of differential diagnosis of benign and malignant tumors, the main distinction between malignant tumor catheters, acinar damage in varying degrees, the film shows the main catheter interrupt the acinar damage to varying degrees, contrast agent spillover. False positive rate should be excluded in the diagnosis, such as contrast agent injection with less, benign tumor compression catheter interrupts, tuberculosis, chronic inflammation of the ductal acinar can produce interruption and destruction. Diagnostic rate of benign tumor 90. 2%, malignant tumor 70. 2%, submandibular gland angiography in the diagnosis of cancer treatment has very important reference value.
