Abstract :Purpose: The aim of this study is to analyze the total factor productivity (TFP) of medical imaging devices in 12 regions of Türkiye for the period 2013–2022 using the Malmquist Productivity Index and to determine whether there are statistically significant differences in the TFP indicators of these devices by region and year. Methodology: Secondary data from the Ministry of Health’s Health Statistics Yearbooks were analyzed using DEAP software with constant returns to scale (CRS) input-oriented Malmquist Productivity Index. Descriptive statistics of the data and correlations between variables were calculated with the SPSS 21.0 program, and the Mann-Whitney U test was applied to statistically test regional and temporal differences. Findings: CT, MRI, and Doppler USG devices showed higher productivity, while ECHO and mammography exhibited lower levels. Productivity was higher in northern and western regions and lower in the south and east, with no consistent improvement observed from 2013 to 2022. Originality: This study contributes to the literature by analyzing the TFP of medical imaging devices in 12 regions of Türkiye using the Malmquist Index, and introduces a novel approach by combining it with the Mann-Whitney U test to assess regional and temporal differences.
