  • Proton magnetic resonance relaxation times T1 and T2 related to postmortem interval : An Investigation on Porcine Brain Tissue

  • Research review (peer-reviewed)abstract
    • In order to establish the validity of in vitro determination of the proton magnetic resonance (MR) relaxation times T1 and T2 in brain tissue at increasing time delay after death or operative excision, 81 brain tissue samples from 23 pigs were analyzed repeatedly. These samples, representing cortex, caudate nucleus and white matter, were studied microscopically after MR measurements. The T1 values exhibited no time dependence and the T2 values decreased slightly during the interval 2 to 90 hours after death. The samples were stored at +8°C between the measurements. These results indicate that reliable in vitro measurements can be obtained in autopsy or surgical brain tissue specimens within 90 hours after death or excision, if handled properly.

  • Regional differences in the proton magnetic resonance relaxation times T1 and T2 within the normal human brain
  • 1986
  • In: Acta Radiologica. - : SAGE Publications. - 0284-1851 .- 0567-8056. ; 27:2, s. 231-234
  • Research review (peer-reviewed)abstract
    • The proton magnetic resonance (MR) relaxation times T1 and T2 were determined in autopsy specimens from 13 different regions of normal human brains. One hundred and seventy-four tissue samples from 25 brains were examined in a pulsed MR analyzer of 0.25 T and were then also studied histologically. There were regional differences in T1 and T2 within the cerebral gray matter but not within the white matter. These regional differences might reflect the different composition and cytoarchitectonic structure of the cortical regions and should be taken into consideration in the interpretation of cortical lesions on MR images.
