本文叙述了75名硒~(75)-氮胺酸扫描摄影检查结果。上颌窦癌(17名)和鼻咽癌(5名)的硒~(75)-氮胺酸含量增多,并在扫描摄影片上获得了恶性肿瘤的局部显影。在15名鼻窦良性肿瘤(囊肿和息肉)病例中,硒~(75)-氮胺酸含量与20名颌面正常人的含量相同。扫描摄影法和放射性测定法可对新生物进行鉴别诊断、确定部位和恶性肿瘤的扩散程度,并能显示复发和估价放疗效果的客观标准。 This article describes the 75 selenium ~ (75) - alanine scanning photographic results. Selenium- (75) -aminine increased in maxillary sinus cancer (17) and nasopharyngeal carcinoma (5), and local imaging of malignant tumors was obtained on a scanning photography. In 15 cases of sinus benign tumors (cysts and polyps), Se ~ (75) - alanine content was the same as that of 20 maxillofacial normal subjects. Scanning and radiometric assays allow the differential diagnosis of neoplasms to determine the extent of site and malignant tumor spread and to demonstrate objective criteria for relapse and radiotherapy effectiveness.
