The role of octreotate scan in discrimination of solitary pulmonary nodule.

Solitary pulmonary nodule (SPN) is one of the most controversial clinical findings in patients. The aim of this study is to use (99m)Tc-ethylenediamine diacetic acid/hydrazine nicotinamide (HYNIC)-TATE scan technique to evaluate nodules. From 2008 to 2010, 21 patients with SPN underwent (99m)Tc-HYNIC-TATE scan after the initial assessment with high-resolution computed tomography and then accurate histopathologic diagnosis was established by trans-thoracic needle biopsy, Video Assisted Thoracic Surgery and thoracotomy.
