摘要
目的:评价肿瘤阳性显像剂99m锝标记的五价二巯基丁二酸[99mTc(V)-DMSA]在咽喉部肿瘤临床诊断中的应用价值,及其在人体的分布情况。方法:对12例经病理学方法证实为咽喉部肿瘤的患者,进行99mTc(V)-DMSA平面及SPECT断层显像,并对99mTo(V)-DMSA在人体的动态分布进行分析。结果:平面显像有9例11个部位出现放射性异常聚集;SPECT断层显像有11例19个部位有明显的放射性浓聚。此外,5例患者发现远处转移病灶。全身分布实验显示,肾脏的放射性滞留明显高于其他主要脏器。结论:99mTc(V)-DMSA,尤其是采用SPECT断层显像,对咽喉部肿瘤的定位诊断和继发性转移病变(包括局部转移灶和全身转移灶)的寻找具有较高的临床价值。
Objective: To evaluate the value of tumor-seeking agent 99mTc(V)-DMSA in patients withpharynglaryngeal carcinoma and its biodistribution in human being. Mathod: Planar and SPECT scintigraphywith 99mTc(V)-DMSA were performed in 12 patients with histologlcally confirmed pharyngolaryngal carcinoma.The dynamic distribution in patients was also analyzed. Result: 9 cases (11 lesions) showed increased uptake byplanar imaging and 11 cases (19 lesions) were clearly demonstrated by SPEC boges. Furthermore, distantmetastatic lesions were showed in 5 patients. Biodistribution in patients showed the accumulation of 99mTc(V)-DMSA in kidney was significantly greater than other organs. Conclusion: These results could suggested the cli-nical utility of 99mTc (V)-DMSA, specially with SPECT, for detecting primary pharynglaryngealcarcinoma andtheir metastatic lesions (both local and distant). 99m Tc(V)-DMSA Tumor-seeking agent Pharyngolaryngal car-cinorna.
