MR imaging of the central nervous system in divers

Aviat Space Environ Med. 1998 Sep;69(9):892-5.


Background: Magnetic resonanse imaging (MRI) frequently reveals asymptomatic cerebral infarctions in the general population.

Hypothesis: The central nervous system (CNS) of divers is affected by a hyperbaric environment even if they are asymptomatic.

Methods: We examined 25 uniformed service divers by MRI and compared them with normal controls.

Results: Of 25 divers, 9 had CNS lesions vs. 2 of 25 controls (p = 0.02). There was a significant relationship between the CNS lesions, age, and smoking.

Conclusion: The divers had a risk of accumulating CNS lesions. These results suggested that divers should undergo periodic medical evaluations and MRI brain scanning.
