title: [Evaluation of 99mTc(V)-DMSA imaging in patients with pharyngolaryngeal carcinoma].
abstract: OBJECTIVE
  To evaluate the value of tumor-seeking agent 99mTc(V)-DMSA in patients with pharyngolaryngeal carcinoma and its biodistribution in human being.
  
  
  METHODS
  Planar and SPECT scintigraphy with 99mTc(V)-DMSA were performed in 12 patients with histologically confirmed pharyngolaryngeal carcinoma. The dynamic distribution in patients was also analyzed.
  
  
  RESULTS
  9 cases (11 lesions) showed increased uptake by planar imaging and 11 cases (19 lesions) were clearly demonstrated by SPECT images. Furthermore, distant metastatic lesions were showed in 5 patients. Biodistribution in patients showed the accumulation of 99mTc(V)-DMSA in kidney was significantly greater than other organs.
  
  
  CONCLUSIONS
  These results could suggested the clinical utility of 99mTc(V)-DMSA, specially with SPECT, for detecting primary pharyngolaryngealcarcinoma and their metastatic lesions (both local and distant). 99mTc(V)-DMSA Tumor-seeking agent Pharyngolaryngeal carcinoma.
