  1. Correlation between 99Tcm-HMPAO-SPECT brain image and a history of decompression illness or extent of diving experience in commercial divers.

    Article - En anglais

    Objectives-To explore the use of 99technetiumm-hexamethyl propylene amine oxime single photon computed tomography (HMPAO-SPECT) of the brain as a means of detecting nervous tissue damage in divers and to determine if there is any correlation between brain image and a diver's history of diving or decompression illness (DCI).

    Methods-28 commercial divers with a history of DCI, 26 divers with no history of DCI, and 19 non-diving controls were examined with brain HMPAO-SPECT.

    Results were classified by observer assessment as normal (I) or as a pattern variants (II-V).

    The brain images of a subgroup of these divers (n=44) and the controls (n=17) were further analysed with a first order texture analysis technique based on a grey level histogram.


    -15 of 54 commercial divers (28%) were visually assessed as having HMPAO-SPECT images outside normal limits compared with 15.8% in appropriately identified non-diver control subjects. 18% of divers with a history of DCI were classified as having a pattern different from the normal image compared with 38% with no history of DCI.

    No association was established between the presence of a pattern variant from the normal image and history of DCI, diving, or other previous possible neurological insult.

    On texture analysis of the brain images, divers had a significantly lower mean grey level (MGL) than non-divers. (...)
