Abstract :The most important factor in determining the planar gamma camera image quality is daily quality control studies. There are many factors including the structure of the system and factors arising from the outside that cause degradation of the image quality. In this case report, we present the findings of photomultiplier tube defect which led to changes in the homogeneity that was detected during parathyroid scintigraphy scanning on a dual-headed SPECT gamma camera and we aimed to emphasize the importance of daily quality control tests for nuclear medicine department
