Brain MRI signal abnormalities and right-to-left shunting in asymptomatic military divers.

Introduction: We conducted a controlled study to assess the prevalence of brain MRI hyperintense signals and their correlation with right-to-left shunting (RLS) in military divers.

Methods: We prospectively enrolled 32 asymptomatic military divers under 41 yr of age and 32 non-diving healthy subjects matched with respect to age and vascular disease risk factors. We examined both groups with a 3-Tesla brain MRI; RLS was detected using transcranial pulsed Doppler in divers only.

Musculoskeletal decompression sickness and risk of dysbaric osteonecrosis in recreational divers.

Introduction: Dysbaric osteonecrosis (DON) is a complication that usually occurs in professional divers or compressedair workers. Its correlation with a previous musculoskeletal decompression injury (i.e.

MRI findings and clinical outcome in 45 divers with spinal cord decompression sickness.

Background: Decompression sickness (DCS) affecting the spinal cord is the most dangerous form of diving-related injury with potential sequelae. This study was conducted to evaluate the relationship between spinal cord lesions on MRI and clinical findings in divers with spinal DCS.

Methods: We studied 45 cases of DCS that were referred to our hyperbaric facility with clinical evidence of spinal involvement during the period 2002-2007.
