Table 1 Mean latency times (± standard deviation) of morphological alterations and neurological distortions after photon and carbon ion irradiation

From: Longitudinal MRI study after carbon ion and photon irradiation: shorter latency time for myelopathy is not associated with differential morphological changes

  Time of onset of morphological and/or neurological alterations [days after irradiation]
BMC CA v CA d Edema CA Syrinx P I P II
Photons 108 ± 47 107 ± 29 149 ± 32 194 ± 17 198 ± 18b 206 ± 23a 199 ± 22a 212 ± 21
12C-ions 84 ± 24 88 ± 18 81 ± 13 122 ± 10 125 ± 10c 124 ± 5 129 ± 7 137 ± 11
  1. Bold printed latency times are significantly different (p < 0.001) between photon and carbon ion irradiated animals
  2. BMC bone marrow conversion, CA v/d contrast agent enhancement in the ventral/dorsal musculature outside the spinal cord, respectively, CA contrast agent enhancement inside the spinal cord, P I (paresis I) at least one forelimb showed signs of neurological dysfunction, P II (paresis II) both forelimbs showed signs of paralysis
  3. a7 out of 8 rats
  4. b3 out of 7 animals showed CA without paresis I
  5. c5 out of 8 animals showed CA without paresis II
