The most important factor in determining the planar gamma camera image quality is daily quality control studies. There are many external factors that cause degradation in the system’s structure and image quality. In this study, we aimed to present the outcomes of photomultiplier tube defect in the double-headed gamma camera with single photon emission computed tomography detector which occurred during daily dimercaptosuccinic acid renal scintigraphy study, which led to changes in the intrinsic homogeneity of the photomultiplier tube, and we emphasized the importance of daily quality control tests in regards to nuclear medicine.
