BACKGROUND We investigated a novel technique, intraoperative (99 m)Tc-Sestamibi (MIBI) imaging (neck and excised specimen (ES)), using a large field-of-view portable gamma camera (LFOVGC), for expediting confirmation of MIBI-avid parathyroid adenoma removal. METHODS Twenty patients with MIBI-avid parathyroid adenomas were preoperatively administered MIBI and intraoperatively imaged prior to i...
A study was undertaken to evaluate the role of positive infarct scintigraphy in the diagnosis of acute myocardial infarction (AMI), using Technetium99m stannous pyrophosphate (Tc-PYP) and a portable gamma camera. Sixty-one patients admitted to the Coronary Care Unit (CCU) with a presumptive diagnosis of AMI or ischaemic cardiac pain were studied. Positive scans were present in 24/25 (96%) patie...
Background: In this study are submitted the radon concentration measurement results of four underground mines: Stanterg, Artana, Hajvali and Badovc, which are owned by Trepça Enterprise, Kosovo. The mines have the same geological formation and from these mines are extracted ores rich with lead, zinc, silver, and gold. The radiation exposures caused by radon and radon daughters was determ...
PURPOSE The solid-state gamma camera 2020tc Imager (Digirad, CA) is now commercially available and has been clinically applied. The present study evaluates the feasibility of equilibrium radionuclide ventriculography (ERNV) within a 3 min period using this camera equipped with a highly sensitive collimator. MATERIALS AND METHODS ERNV was performed from the best septal position (left anterior ...
gamma camera is an important apparatus in nuclear medicine imaging. its detection part is consists of a scintillation detector with aheavy collimator. substitution of semiconductor detectors instead of scintillator in these cameras has been effectively studied. in this study, it is aimed to introduce a new design of p-n semiconductor detector array for nuclear medicine imaging. a p-n semiconduc...
