İstanbul Tıp Fakültesi, Nükleer Tıp AD The aim of this study was to evaluate the value of 99mTc penta DMSA scintigraphy in larynx carcinoma and its cervical metastases. Images were obtained 1 -2 hour after injection of 10 mCİ 99mTc penta DMSA in 13 patients with larynx carcinoma and 5 control subjcets. The scintigraphy showed focal intense uptake in the anterior midline of the neck in patients with larynx carcinoma and no focal intense uptake in control subjects. The scintigraphy results were compared with histopathologic results of neck surgery. It was found a 92 % sensitivity, a % 100 spesivity for primary lesion and a 100 % sensitivity and % 88 spesivity for metastatic cervical lymph nodes. We concluded that 99mTc penta DMSA sicintigraphy is a sensitive and specific method for the evaluation of larenks carcinoma and cervical larynx node metastases. Keywords :
