本文应用~（99）mTc-硫化胶体（~（99）mTc-Re）对21例头颈部恶性肿瘤患者进行淋巴结显像。选择了4个注射部位;注射到11名患者的顶骨区皮下组织中，注射到6名患者的磨牙后区粘膜下层中，注射到2名患者的耳后区皮下组织中，注射到2名患者的甲状腺中。注射后3小时进行荧光造影。85.7%的患者患侧颈部可见，90.5%的患者健侧可见。可视化包括以下区域：颏下、下颌下、颈深、附件和锁骨上区域。在患侧共观察到102个淋巴结（平均每例患者4.8个），健康侧共观察到110个淋巴结（平均5.5个）。组织学上，21例患者中15例有淋巴结转移，6例无。在这21例患者中，66.7%（14/21）的患者在可视化区域中确认了淋巴结转移。这项技术似乎是一个相对简单和有效的方法成像区域淋巴结在头颈癌治疗前和颈部手术后。
To achieve the visualization of regional lymph nodes by lymphoscintigraphy, 21 patients with head-and-neck cancer were studied with the aid of 99mTc-labeled rhenium sulfur colloid (99mTc Re). Four injection sites were selected; the injections were given into the subcutaneous tissue of the parietal area of 11 patients, into the submucosa of the retromolar area of 6 patients, into the subcutaneous tissue of the postauricular area of 2 patients, and into the thyroid glands of 2 patients. Lymphoscintigraphy was done three hours after the injection. The cervical regions were visible in 85.7% of the patients on the affected side and in 90.5% on the healthy side. The visualization comprised the following regions: submental, submandibular, deep cervical, accessory, and supraclavicular regions. In total, 102 nodes were visualized on the affected side (average 4.8 per patient) and 110 nodes in the healthy side (average 5.5). Histologically, 15 of 21 patients had lymph nodes metastases and 6 did not. Of these 21 patients, 66.7% (14/21) had confirmed lymph node metastases in the visualized regions. This technique appears to be a relatively easy and efficient method of imaging the regional lymph nodes in head-and-neck cancer both before treatment and after neck surgery.
