Postoperative complications such as vertebral decompression can lead to hematoma formation and infection. The differentiation of hematoma from infection as a postoperative follow-up is important in assessing future treatment options and the need for surgery. The aim of this study was to differentiate between spinal epidural hematoma, spinal epidural abscess and pyogenic spondylitis based on the ADC and T2 values obtained using DRM. The T2 and diffusion weighted T2 (ΔT2) values were significantly higher in abscesses than in hematomas, and even higher in pyogenic spondylitis.DRM allows to differentiate hematoma from infection.
