| Περίληψη: | Objectives: To evaluate the effect of quaternary ammonium compound (QAC) disinfection on the radiographic image quality and chemical integrity of photostimulable phosphor (PSP) plates. Methods: Radiographic image quality was assessed using 2 radiographs of an acrylic-block and 2 radiographs of an aluminum step-wedge acquired before disinfection and after 10 groups with 10 disinfections each. These radiographs were acquired with 2 PSP plates. Brightness, noise, uniformity, contrast, and presence of artifacts were analyzed. Analysis of variance compared gray values between disinfections (α = 0.05). Chemical integrity was assessed using mid-infrared Fourier-transform infrared (FTIR) spectroscopy on the PSP plates tube side, comparing disinfected plates with a non-disinfected control. Metal disk corrosion of the plates was visually inspected. Results: Brightness decreased after 100 disinfections compared with radiographs obtained after 20 disinfections (P = .026). Uniformity increased for all disinfection groups compared with baseline radiographs (P < .001). Radiographs obtained after 100 disinfections showed higher contrast than those acquired after 20 disinfections (P = .005). Noise did not differ (P > .05). Artifacts were observed after 40 disinfections. Fourier-transform infrared analysis showed hydration followed by degradation of the PSP plates after 100 disinfections. Metal disk corrosion occurred after 10 disinfections. Conclusions: Quaternary ammonium compound disinfection affected brightness, uniformity, contrast, produced artifacts, chemical changes, and metal disk corrosion of the PSP plates. Advances in Knowledge: This study is the first to assess the impact of disinfecting PSP plates with QAC. Results showed that QAC is not a viable option since its use produced changes in image quality and integrity degradation. (© The Author(s) 2026.
