After the start of renal scintigraphy in a 32-year-old woman, there was an abnormal view in frame 6 that was simultaneous with the start of ringing of a mobile cell phone that was in the patient's trousers pocket. In frame 6 of the flow phase, some bright dots were observed, suggesting photomultiplier tubes. Immediately after that frame, in spite of continued ringing of the mobile cell phone (up to 1-2 minutes), the imaging frames came back to a normal situation. In the case, electromagnetic interference from the mobile cell phone may disrupt the photoelectric functioning of photomultiplier tubes during scintigraphy.
