BACKGROUND Apoptosis is a major mode of hematological tumor death after radiation. Early detection of apoptosis may be beneficial for cancer adaptive treatment. 99mTc-HYNIC-annexinV has been reported as a promising agent for in vivo apoptosis imaging. The purpose of this study is to evaluate the feasibility of in vivo99mTc-HYNIC-annexinV imaging of radiation- induced apoptosis, and to investiga...
Background and purpose: Bombesin shows very high-affinity for the Gasterin releasing peptide (GRP) receptors which are over expressed in different human tumors such as breast and prostate. The aim of this study was to identify a new bombesin derivative labeled with 99mTc via HYNIC that might be used as a noninvasive tool for diagnosis of GRP receptor expressing tumors. Materials and methods: P...
There is a critical need to develop diagnostic procedures enabling early detection of tumors while at a curable stage. Technetium 99m (99mTc)-labeled VQ peptide (99mTc-HYNIC-VQ) identified through screening phage display peptide libraries against fresh human colonic adenomas was prepared and evaluated for tumor detection. 99mTc-HYNIC-VQ was prepared by a non-SnCl2 method with more than 99% radi...
PURPOSE The aim of our study was to assess diagnostic accuracy of Tc-99m depreotide and Tc-99m-EDDA/HYNIC-TOC scintigraphy for evaluation of pulmonary lesions that appeared ambiguous on computed tomography (CT). MATERIAL AND METHODS Forty-nine consecutive patients (37 men and 12 women; mean age, 60 ± 11 years) with 60 pulmonary lesions on chest radiography and CT were referred for nuclear ima...
