[The value of 99mTc-DX105 cervical lymphatic imaging in detecting cervical lymph node metastasis of laryngeal and hypopharyngeal carcinoma].

Objective: To study the value of single photon emission-computed tomography (SPECT) lymphatic imaging by percutaneous injection of 99mTc-DX105 in detecting cervical lymph node metastasis of laryngeal and hypopharyngeal carcinoma.

Method: One-three days before the operation, 185MBq 99mTc-DX105 was injected via bilateral mastoids portion percutaneously in each of 30 patients with laryngeal and hypopharyngeal carcinoma, and thus SPECT lymphatic imaging was conducted. Then, the diagnostic result was compared with those of pathological examination of neck dissection specimens.
