Prompt
Parents of a 19-year-old with first-episode psychosis want an fMRI and PET scan to 'prove the chemical imbalance' and ask whether a normal MRI means the illness is not real. You must explain clinical vs research imaging, red flags that would change the plan, incidental findings, and recovery framing without jargon dumps.
Station brief
Format. Communication station, approximately 7–10 minutes after reading. You are the psychiatry registrar in an early-psychosis service. [1]
Candidate instructions. Build rapport. Explain why we sometimes use structural MRI (to look for medical problems), what it cannot do (prove or disprove a primary psychiatric diagnosis), and why research fMRI/PET colour maps are not personal diagnostic tests. Address the "chemical imbalance photo" myth using accurate but simple dopamine-pathway language. Invite questions; safety-net for new neurological symptoms. [1][2][3][4]
