Postmortem MRI brain scans of 13 patients who died from . stated that while OCS had some evidence of clinical utility, clinicians were divided on its routine use in a PCOD setting; the authors suggested the alternative of a short 34-day course of OCS to trial therapy responsiveness before beginning a more prolonged course [19], level 2A]. 8600 Rockville Pike Singh CV, Jain S, Parveen S.
