Feasibility of portable gamma camera imaging in intraoperative radioguided parathyroid adenoma identification
Novel surgical applications include radioguided procedures in parathyroidectomy operations. In order to investigate the feasibility of usage of the portable gamma camera in parathyroidectomy operations; intraoperative radioguided parathyroidectomy operation was performed in three hyperparathyroidism patients with inconclusive preoperative parathyroid scintigraphy results. Intraoperative portabl...
متن کاملEvaluation of the difference-correction effect of the gamma camera systems used by easy Z-score Imaging System (eZIS) analysis
OBJECTIVE We examined the difference of the effect by data to revise a gamma camera difference. The difference-correction method of the camera is incorporated in eZIS analysis. METHODS We acquired single photon emission computed tomography (SPECT) data from the three-dimensional (3D) Hoffman brain phantom (Hoffman), the three-dimensional brain phantom (3D-Brain), Pool phantom (pool) and from ...

متن کاملDetermination of Optimum Planar Imaging Parameters for Small Structures with Diameters Less Than the Resolution of the Gamma Camera
Introduction: The limited spatial resolution of the gamma camera hinders the absolute quantification of planar images of small structures. The imaged structures are affected by partial volume effects (PVEs), which can spread activity and lead to underestimation of the regional distribution. The use of optimum planar parameters reduces the impact of the limited spatial resolution of the gamma c...
