Cerebral perfusion SPECT imaging for assessment of the effect of hyperbaric oxygen therapy on patients with postbrain injury neural status

摘要

Objective: To evaluate the effects of hyperbaric oxygen (HBO) therapy on patients with postbrain injury neural status.Methods: Two to 4 courses of HBO therapy and/or medications were used to treat 320 patients who were randomly divided into two groups. Assessment was made with 99mTc-ethyl cysteinate dimer (99mTc-ECD) single photon emission computed tomography (SPECT) before and after treatment. Results: There was a significant difference between the HBO therapy group and the non-HBO therapy group. HBO therapy was superior to medication treatment alone in the recovery of clinical symptoms, control of epilepsy, and resolution of hydrocephalus (P<0.01). Conclusions: HBO therapy has specific curative effects on patients with postbrain injury neural status, and 99mTc-ECD SPECT could play an important role in diagnosing postbrain injury neural status and monitoring the therapeutic effects of HBO.
