Resting-State fMRI in Radiologists with Night Shift–Related Sleep Deprivation: A Regional Homogeneity Study

Motivation: A growing body of research focuses on the impact of night shifts and fatigue on radiologists' diagnostic accuracy. Goal(s): This study investigates the changes in local brain activity and their association with low-level basal cognitive functions (e.g., alertness) in radiologists following night shift–related sleep deprivation (SD). Approach: Regional homogeneity (ReHo) variability was calculated to reflect the characteristics of brain activity. Results: The ReHo values changed in some brain regions after seven days of rest after a night shift. Impact: The results of this study can be the basis for radiologists to advocate for effective countermeasures to deal with the adverse consequences of SD.
